One-Step Installation

The Curt Echo is unique for its plug-and-play installation. With no wiring, modules, or knobs to install, setting up the Echo is a breeze.


Curt Echo Wireless Brake Controller Installation

The main unit plugs into the 7-way at the rear of your vehicle and provides a port for plugging in your 7-way trailer connector. Use the included strap, found inside the cap, to secure the Echo in place. It will help ensure a constant connection between vehicle and trailer.


That done, download the OneControl app on your Apple or Android smartphone and wirelessly pair the unit to your phone via Bluetooth, following the in-app instructions. It should take about 5 seconds for them to pair. Once paired, the LED light on the unit will turn a solid blue. Plug in your trailer's 7-way and let the whole system calibrate for another 5 seconds. When the LED turns green, configure your desired trailer brake settings in the app and save it as a profile. Then you're ready to tow!


Note: See etrailer.com's exclusive 7-way upgrade kit for brake controller installation (ETBC7L - sold separately) if you don't already have a 7-way plug at the back of your vehicle.


Control Your Towing with Your Smartphone and an App

Besides the crazy-easy installation, the Echo is unique for giving you control of your towing through your smartphone. You can set the maximum braking output, adjust the braking sensitivity, apply the manual override - all from the OneControl app.


Completely wireless, the Echo connects to the app via Bluetooth. You can save multiple towing profiles in the app, a big plus if you have a fleet and want to be able to just select a pre-set configuration and get towing. And don't worry; after you've downloaded the app, you don't need to have data on to use the app with the brake controller. You'll be able to receive calls and texts and access your other apps.


User-Friendly OneControl App

Simple, intuitive, and user-friendly, the OneControl App makes it wicked easy to manage your settings and control your trailer.


how does the One Control app work

1. Manual Override

This big orange button in the middle of the app is your manual override. Press and hold the button, and the brake controller will smoothly apply the trailer brakes without applying your vehicle's brakes. This is perfect for stopping sway or controlling your trailer's momentum in an emergency.


Curt Echo App Manual Override Button

Quick tip: Put manual override right at your fingertips by adding this button (C83HR - sold separately) to your dash. The app must be running for the button to work, but it can be in the background while you use other apps on your phone. The button has an adhesive pad for a quick-stick installation and includes an easily replaceable battery.


2. Brake Output Indicator

The outer ring gives you a visual indicator of how much power is being applied to the trailer brakes. This is determined by your max output setting.


3. Max Output

Braking output is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop.


To set your maximum braking output, tap this button and increase or decrease using the + and - buttons. You want to set the braking output as high as you can without locking up the brakes. Once you've set up the brake controller the first time, you shouldn't need to adjust the settings until the trailer load changes, you switch trailers, or road conditions change.


4. Sensitivity Level

This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the max output level. This is a great adjustment to make when you're towing a heavy load and the trailer will need more umph to bring it to a stop so it doesn't push your vehicle forward.


Just like max output, if you need to change your sensitivity level, use the + and - buttons. If your vehicle takes too long to come to a stop, increase the setting. If it stops too abruptly, lower the setting. You may also need to adjust the sensitivity based on your own preferences, or when the trailer load or road conditions change.


5. Vehicle Hazard Lights

If you turn on your vehicle's hazard lights, there's a chance the trailer brakes will pulse on and off as the lights flash. Turn this setting on any time you activate your hazard lights to prevent this problem.


Save Multiple Trailer Profiles

Curt Echo App saves multiple trailer profiles

Get on the road faster by saving your settings. With the app, you can add and store multiple profiles for both trailers and vehicles so that your preferred settings will be ready to go as soon as you hook up. This is perfect if you own a fleet and don't want to have to reset the controller every time you swap out trucks, trailers, or drivers. You'll have the ideal settings saved and waiting for you. To switch between profiles, just swipe left or right.


OneControl: One-Stop App for Towing

If you like the idea of monitoring your trailer from your phone, the other OneControl systems could be a great fit for you.


The Curt True Course (C94VV - sold separately) is an advanced Bluetooth sway control system that automatically triggers the trailer brakes (independent of the vehicle's brakes and the brake controller) when it detects dangerous trailer movement. The Curt Tire Linc (C54VV - sold separately) Bluetooth TPMS monitors the temperature and pressure of your trailer tires. All of these systems use the OneControl app so you can manage all of them in the same place on your phone.


LED Status Indicator

troubleshooting Echo brake controller

The LED indicator light on the top of the plug-in module will show you when the brake controller is connected. You can also check the LED for simple diagnostics when you need to troubleshoot.


Weatherproof Construction

Is the Curt Echo weatherproof

Because the Echo mounts outside the vehicle, it's designed for maximum weather resistance. The unit is filled with an epoxy resin that seals off the internal components from moisture and the elements. The Echo also has a soft locking tab for connecting to your 7-way plug that reduces vibration and helps ensure a constant connection.


Proportional Braking

What is proportional Braking

The Curt Echo brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.


The Echo uses an internal 3-axis accelerometer to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to ensure that your trailer slows at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

I like the fact that I have a proportional brake controller I can stick in my glove box. It doesn’t have to be hardwired to the vehicle which is nice because I can use it on different applications. This one is definitely a plus over time delay brake controllers.

Mark

After an initial issue and replacement, the product has worked very well. Having an adjustable proportional controller that you can throw in your glove box is pretty handy. It’s response time is very quick.

We have been using the Echo wireless brake controller for about a year with our little travel trailer. In general it works well, no problems with the installation or connection to our phones. There is a little rubber strap that supposedly keeps it attached to the vehicle, but it is pretty useless. We keep a bunch of 1cm wide zip ties in the car in order to secure the unit to our car.

Mark

3/11/2024

The echo wireless works well. It is easy to setup for different trailers or road conditions. The new software update improves connectivity. The little safety strap that it came with is long gone, and it was useless to begin with. I just keep a bag of zip ties in the car to secure the echo to the cars seven pin connector.

@Mark That's a nice solution!

Customer service response is prompt. Order arrived quickly. I’ve attached, synced, and tested the controller on my 2020 Tacoma, pulling my 16ft travel trailer. Lights and app indicate it is working. I’m still testing adjustments, as I’ve never used a brake controller. I saw some reviews that complained about brake pulsing at low speeds. I have NOT experienced this problem. Manual actuation works well at low speed. Information says app must run in the foreground. I’m trying to determine what that means. Can I open the app and switch to another app, or does the app need to stay on constant display?

Etrailer Expert

Brooke M.

2/26/2024

Yes! The app should be the one on constant display on your phone screen; the one you are viewing. It looks like the reason is if its running in the background, if you have a different app on display while towing, it can cause delays in breaking times. Best to be safe and just run the OneControl Auto app when towing.

This controller has worked flawless for me. I’ve used it on a 2009 Lexus RX350, 2022 Lexus RX350, and 2022 Lexus GX460. Never an issue connecting or operating. My father, on the other hand, has the exact controller for use with his 2018 Ford F-150, and has had many issues with connection and operation. I love it’s modularity and simplicity.

Dan

3/13/2024

Still using this controller frequently, even though my GX has a pigtail for a wired controller. This is just so simple and quick to plug in when I need it, and take out when I don’t. Zero flaws, zero hiccups, zero issues.

2019 Honda Ridgeline

The Curt Wireless brake controller installed easily on my 2019 Honda Ridgeline for towing my 24' travel trailer. It worked well on the one occasion that I had to use it. Nice to have the visual in the app on how the brakes were being applied.



by:

The Echo is a convenient trailer brake. It's easy to set up and use every time I hook up my trailer. I use Bluetooth from an old smartphone mounted to the left of of my steering wheel so I can keep my cell phone free.

The only problem is that the rubber strap kept getting un latched from the rubber pin. So I just use two bungee-balls to keep the ECHO connected to the car harness and the trailer plug. (see Photo)

Chevrolet Tahoe

A great controller. It was simple to setup and use. I love the ability to use it in different vehicles ---- and no wiring hassle. Plug and play, make a couple adjustments and it worked like promised. I have showed it to several friends, who were totally amazed, had no idea there was a product like it out there. Towing a 18ft enclosed trailer with a Tahoe presently.



by:

So far it's doing exactly as it was designed to do. Only issue is that stupid rubber strap. It has a button on it and as I was trying to loop this thing over the plug door, it flew off. Why would you make one removable? In any case, I put a zip tie around it. I was lucky to find the button on the ground and tried it again only for it to fly of once again. I like the controller how it works and it's simplicity



by:

Simple and quick way to set up a vehicle for trailer brakes. Cost effective, too, as you can use it for multiple tow vehicles. Easy to pair, I use an older “obsolete” iPhone with Bluetooth instead of my everyday iPhone. Be careful, though, this one is a replacement for one that vanished while camper was in for service.



by:

It is a new year and this five start rated product is now a three star. The reason being is the forced update to the "Lippert One Control" app - away from its original CURT app. The Lippert One Control app is not working with iOS. It is a known problem with BT, location, font size, screen brightness, and zoom. Currently, one has to restore the Display Settings on iPhone to the default status to make the app work. It gets stuck on the "Accept/Cancel" screen because of font/zoom settings. Though working with Lippert support, it's 2.20.24 and the app is only functional when these default settings are applied. The default settings get applied to the entire phone making my phone impossible to see, to read, to determine color. The font is tiny, it's not bright, I cannot zoom, so I'm not sure what's taking so long for Lippert developers to get updates rolled out. The forced update to the Lippert One Control app rolled out in late 2023 and it never worked. Reviews in App Store are 1.3 and issues are still compounding. The brake controller may work without the app but the settings you need may not be the presets. I could tell the controller was not how I set it up on CURT app, so I had to drive without a brake controller. Until App Store reviews indicate consistent excellent status as the CURT app did, without rendering your own utility worthless, I cannot recommend this innovative and wonderful product. It worked well under CURT but Lippert still hasn't figured out what is going on and did not think more broadly when developing. Great product if it worked!



by:

Works perfectly and no fooling around with wires! Worth every penny! AND, if you have multiple vehicles, you don't have to install a brake controller on all of them, just plug and go! I love it!!!!!



by:

As long as you follow the directions for hooking it up precisely, it works marvelously. Especially, if like us, no OEM brake controller was available for our Jeep Grand Cherokee.

I give it a low rating, however, because it is made very cheaply. Just from regular use (plugging it in and unplugging it), the unit cracked, and then after 1-2 more uses it completely fell apart. See the pictures.

I'm having trouble with it on my small trailer locking up the brakes

Etrailer Expert

Jenny N.

2/9/2024

Thank you for reaching out. Have you been able to adjust the output and sensitivity on the controller? Lowering the settings can prevent the brakes from locking up.



by:

Fantastic / effortless! I drive a Volvo XC40 and needed the most minimal, non-intrusive brake controller I could find. All you need is the corresponding app, you pair this controller to the app via bluetooth, and configure it (just 2 settings for trailer brake output & sensitivity) and you're good to go. No need to rely on the app during driving at all, the brake controller stores the settings and just does its thing without you needing to look at the app or have it open. It's handy for testing the brakes, there is a button on the app where you can virtually press the brakes, so I stand by my trailer brakes, press the button, and test that I hear them engaging - super convenient since I do setup alone. Safety features ensure that if the phone loses connection, the brake controller just keeps working. Super happy with my purchase.

8/21/2023

Product has still been perfect 1 year later. It just works every time, Ive used it for towing in a dozen+ trips and its been perfectly doing its job without issue.



by:

Works very good. I only tow a cargo trailer a few times per year and of course my new SUV DIDN'T have the built in trailer control like my last truck. I always hated the ad-hoc controllers (hit my knee every time) and because of staffing, the wait time to have my shop install one was about 3 months! So I bought this and have been very happy with it. I can't tell the different between and a regular brake controller. I believe it is using an accelerometer built inside it to determine when to apply braking. They did a damn good job programming it because it works well for me and I have had no problems. Just a heads up there is an app required you need to download (free) in order to set it up. Best part is, when I part with my SUV, this stays with me.



by:
2022 Ford Bronco

Picked up my teardrop in ABQ on 2/17/23, and the Echo was easy to mount and sync to my phone, and worked flawlessly the 175 mile trip home. I also got my longer 3-way curt ball mount from etrailer, and it is a beast and also worked perfectly!



by:

Easy set up. Very smart brake controller. Brakes only as needed, and is very adjustable. I was skeptical about these proportional brake controllers (they use an accelerometer to sense how fast the towing vehicle is slowing down), but I am a believer now. Only thing to check: make sure your 7 pin connector’s auxiliary 12V is connected to at least a 20A fuse. The product says it needs to be connected to a 30A breaker, but I don’t think you’ll find many vehicles where that’s the case. 20A seems standard, and in my case more than enough. I am not sure is 20A May be a problem for those needing to brake two axles though. Worth looking into that before buying the controller.

Still enjoying using this wireless blue tooth controller. My only gripe is that the little rubber strap that comes with it is too flimsy and does not lock in place. I got rid of it.



by:
2010 Ford Expedition

It works ok but is not as proportional as I would like. My trailer 20 ft box empty is not bad at speed with a 40% and 1 proportional. Low speed 10 mph down jerks and will and even lock brakes but only at low speed.

I would prefer Ford factory control but it is not offed as an add on for my Expedition and I’m not happy about that.



by:

I used the wiring harness and 7/4 pin receiver from etrailer to wire my 2021 Toyota Highlander to use the Curt Echo. It worked flawlessly the first time. So far I haven’t needed to make adjustments from the original settings for my R-Pod 180 travel trailer. I do wish there were better instructions for initial set up.



by:

Well I got this unit for my 40' motorcoach. Unfortunately it doesn't stay connected on my phone through the app inside the coach. But once you open the app and correctly set the app with your settings for the trailer or whatever you're towing it does a great job. So that's why it only got 4 stars. At least I didn't have to wire my whole coach, what a pain that would've been.



by:

Initially wouldn’t connect to iPhone but after uninstall/reinstall of app it was fine. After literally traveling around the entire US I have to say it was a blessing with plug-and-play simplicity and total control over braking parameters. The phone lost Bluetooth connection a few times while traveling but the controller maintains the program so no big deal. For me it was nice to see the braking rate on the phone graphic. GREAT PRODUCT! 5 stars!



by:

I just received the wireless brake controller so my experience using it is still little, however it was very easy to setup. It took about 2 minutes to plug in and get setup once the app was installed on my phone. I pulled my trailer around the block and worked to setup the sensitivity and it seems to work flawlessly. I like how I can setup multiple profiles for my different trailers. I lease my truck to it is nice that I don't have to install wiring and install the controller onto the dash of the truck knowing I will most likely turn it in at the end of the lease

Dana

2/6/2023

I have had the wireless brake controller for about a year now, and I have to say it has worked flawlessly. It connects to my phone each time without fail also. It is a bit more expensive than a wired controller but in my opinion, the ease of use and ability to use in different vehicles makes it well worth the investment.



by:

We cannot find a setting other than the very lowest possible settings of both the max output and sensitivity without our trailer brakes grabbing. This became even worse in the new app which we were required to switch to without any warning. This is completely unacceptable and dangerous!



by:
2022 Nissan Frontier

When this arrived I opened the box and did not have any packing material to cushion the contents inside to prevent damage. The right side of the controller was cracked open (screw missing) and one of the pins inside is bent. I was able to repair the damage on the side. Have not plugged it in to see if it works.

  • Will Curt Echo Brake Controller Work on 2014 Lexus GX 460 with 7-Way
    The Curt Echo Trailer Brake Controller # C51180 that you referenced is a perfect option for your Lexus GX460 that features the factory 7-Way connector. This unit will plug right into that 7-Way to provide you with an excellent proportional brake controller that will automatically send power back to the trailer brakes in correspondence to the rate of deceleration in the vehicle (the harder you brake, the more power it will send back). After plugging in the controller all you need to do...

  • Curt Echo Brake Controller Won't Power On But 12 Volt Circuit Works
    Thank you for purchasing from etrailer the Curt Echo Wireless Trailer Brake Controller # C51180. Normally if the Echo will not power on, the issue is with the 12 volt circuit on the 7-way and we'd have you test that. However, in your case, since you know the 12 volt circuit is working, and the Echo is simply not receiving power, the controller has become defective and will need to be replaced. The good news is that Echo does have a lifetime warranty, so a replacement from Curt isn't something...

    We haven't specifically used in on a 2020 or 2021, but as long as your Ford Explorer ST has a fully functional 7 way trailer plug then the Curt Echo # C51180 will work just fine. This is designed to be a universal controller that avoids any wiring required inside the vehicle, so it's a great solution if you don't want to mess with having a brake controller in the cabin of the vehicle or just want to be able to reliably tow with multiple vehicles; it'll also work with just about any vehicle...

    I do have an option for you but hardwired trailer brake controllers aren't ideal for a 2022 GMC Canyon as they will require you to splice into the vehicle and run wires throughout.

    You must have received an older version. The # C51180 Curt Echo we offer is the latest model which offers the security strap (as shown in the linked product description). Curt doesn't offer the strap as an individually available item, as the attachment points are molded into the body of the controller. Luckily, Amazon is pretty good about returns, so you could return the one you have and purchase a replacement from us. I've linked to a product demonstration video featuring the Curt #...

  • Can I Use the Curt Echo Even Though the Factory 7 Way Connector is Angled Down
    We've actually seen this before with the Curt Echo # C51180 and Audi factory trailer plugs before, and the downward angle on your 7 way bracket will not affect the operation of the controller. You won't need to reposition the plug and the Echo will work in this orientation, so there's nothing to worry about there. You also should be able to plug in without any issues, but it's likely you'll get some dragging when going over speed bumps and such, so if that becomes an issue and there is...

  • Towing Weight Capacity of 2008 Chevy Avalanche with 5.3L Engine
    I took a look at the online version of the owner's manual for your 2008 Chevy Avalanche and it looks like with the 5.3L engine it has a towing capacity of 7,000 pounds for the 2WD model or 7,200 pounds for the 4WD model. I do recommend verifying this by checking your copy of the owner's manual as well. When looking for a trailer you can safely pull the most important thing to look at is its GVWR (Gross Vehicle Weight Rating), which refers to the most it can weigh when fully loaded. A...

  • Can A Curt Echo Brake Controller Be Used On a 2019 Ford F-150 With A Factory Brake Controller

We typically won't fully configure the brake controller to the truck and trailer in our videos since we the owner might have different preferences than we do while towing. That being said, on the main page you'll have your manual override button, max output...

  • Troubleshooting Curt Echo Not Connecting To iPhone 13 and Changing From Blue To Green Flashing Light
    It sounds like you may have something wrong internally with the Curt Echo # C51180. The device should only flash blue when a trailer is not connected and the device is not connected. It should only switch to the flashing green when a trailer is connected but the device is not not connected. If plugging in the trailer is what you are doing when it switches to green do be sure to check your phone settings and ensure the bluetooth is enabled as that is the only portion for the phone which...

  • Easy to Install Brake Controller Recommendation for 2002 Fleetwood Discovery
    We have not been able to determine if your 2002 Fleetwood Discovery has brake controller prewiring so that would mean you'd most likely have to hardwire in a controller. OR, you have the option to simply plug in the Curt Echo Mobile brake controller part # C51180. You'd just plug this into your 7-way, sync it to your smart phone, and then you'd have a fully functional brake controller without requiring the headache of wiring up your motorhome.

  • Can Multiple Devices be Connected to the Curt Echo Mobile Trailer Brake Controller 51180
    Yes, the Curt Echo Mobile Trailer Brake Controller part # C51180 can be used with multiple devices. However, only one device can have the application running on their phone while in range.

  • Is Curt Echo Mobile Trailer Brake Controller Recognized by MTO in Ontario, Canada
    I spoke with my contact at Curt regarding the Echo Brake Controller # C51180 and he said he is not certain if the controller is recognized by the MTO simply because this is not a certification they sought when testing the unit. He did say though that the controller meets all the same standards as all other Curt brake controllers, which are legal for use in Canada. I am not sure what type of testing is required or if the MTO is looking for anything in particular with regards to the brake...
