Welcome to an entirely new towing experience. The Curt Echo brake controller puts you in control of your trailer's braking with mobile, Bluetooth operation. The portable unit installs in seconds and allows you to make braking adjustments straight from your smartphone. Easily transfer the Echo between vehicles and store it when it's not in use.

Simple, Fast Setup

Curt Echo Plug In Brake Controller

With no wiring, modules, or knobs to install, setting up the Curt Echo is a breeze. Just download the Echo Smart Control app on your Apple or Android smart device and follow the in-app instructions. The brake control unit plugs into the 7-way at the rear of your vehicle and provides a port for plugging in your 7-way trailer connector. When all the connections are made, wirelessly pair the unit to your phone via Bluetooth. Once the unit is paired, configure your desired trailer brake settings in the user-friendly app.

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.

Echo Smart Control App

The Echo Smart Control app is free to download and use. Scan the QR code included with the Curt Echo or search Echo Smart Control in the Apple App Store or Google Play Store.

Curt Echo Manual Control

The custom-designed app allows you to control brake settings, calibrate output, and monitor all braking activity with the touch of a finger. If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - the manual override function is easily accessible in the app. Press and hold the large orange circle to manually activate your trailer brakes.

The app will also alert you in the event that your trailer is overloaded or becomes disconnected during travel. Should your smart device ever lose connection, the Echo will default to the settings of the last profile used. So even if your phone battery dies, you can still count on getting proportional trailer braking as long as the unit is in use.

There's no need to worry about missing a call or running multiple apps either. The Echo Smart Control app will continue running in the background if you get a call or switch between apps, and it will not interfere with your vehicle's hands-free multimedia system.

Create Multiple Vehicle-Trailer Profiles

Vehicle Trailer Profiles

The app has the ability to sync up to 5 Echo devices, and the memory function allows you to save unlimited vehicle-trailer profiles. This makes it easy to transfer the Echo between towing setups. This convenience, along with the plug-and-play design, makes the Echo perfect for either occasional towing or commercial fleets.

Weatherproof Construction

Curt Echo Features Diagram

Because the Echo is made to be outside the vehicle, it's engineered for maximum weather resistance. The unit is filled with an epoxy resin that seals off the internal components from moisture and the elements, ensuring long-lasting operation despite rain, snow, dirt, mud, and more. The Echo also has a soft locking tab for connecting to your 7-way RV-style plug. This tab helps to reduce vibration and improve connectivity.

LED Status Indicator

Curt Echo Diagnostic Indicator

A single LED on the body of the Echo shows the status of the brake control unit so that you can easily troubleshoot any problems that may arise.

Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner.

Once the Echo is installed, it will sense - via an internal 3-axis accelerometer - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Almost EXCELLENT, small problem; won's stay inserted into the 7way socket. I've emailed etrailer and asked if this is a common problem, I'm sure they'll either have a solution or I'll come up with a strap of some sort. Fortunately ours is a 5th wheel and the connector is in the bed. If it was off the bumper it'd be a bigger problem for sure!! But he controller works great, easy to set up and I don't think I'll hit my leg on it. 647505

Perfect after a year, very pleased with purchase!

Wasn’t a great fit for my application because my 7-pin socket on the car angles down at 45 degrees and after the brake controller is installed and the trailer pigtail plugged in the cable hangs down pretty far. It hangs lower than the safety chains. It could be an issue. Otherwise, the controller paired right up and seems to work fine. 691278

This unit draws power from my travel trailer so will only work when hooked up to it. 705715

Another great product from Curt and eTrailer! I was looking for a trailer brake setup that I could use on different trailers. The Curt product and eTrailer video helped me select this product. It's easy to set up and use, and works great with my tandem car hauler trailer! 704265

2018 Jeep Cherokee

I have not used it as of now. It is exactly what I wanted and works with My Jeep Cherokee that no one could tell me where to get brake signal to install a normal brake controller. This is a great option because I had the dealer install the a 7wire connection from Jeep and hitch but they know how to install a brake controller. Also there is nothing in the cab or holes drilled in the dash. Just all you need is a smart phone. Great concept and item to used on any vehicle even the new ones with all the things that controlled by the computer on vehicle and has to be reprogrammed by the dealer at a high cost. Will post later when I have used it and will let you know how it works. 607002

This is working great. Used going from Mississippi to Grand Canyon and back. Great for those vechile a that are hard to connect brake controller to and Dodge vechile said that dealers charge to program computer so permanent controller will work.

It’s been a year and my controller is working Great, now that I’m retired I’m using my trailer more and I’m very pleased with the ease of use and flexibility this brake controller provides.

Dodge Ram Pickup

PROS: In my Tacoma there is really not a good place to mount a controller that is easy to see. Since this product uses my iPhone I can (using a ram mount) put it anywhere I want. Best visibility of any brake controller I have ever used. Button for applying trailer breaks manually works much better than I expected. Very easy to set up. CONS: 1. Minor gripe, since this unit rides outside your truck it needs to be tough, the plastic that it is made of seems like it would not survive much in the way of impact. 2. The unit does not fit snuggly in my standard Tacoma 7-pin receptacle. Added a single layer of duct tape around the circumference to resolve. 656462

Use it once or twice a month on average. Seems to be holding up just fine.

2019 Dodge Durango

This is a great brake controller. The only issue I had was that the instructions state that you need your car engine running and it would connect via Bluetooth to the controller.. However, in my case, and it just may be my car model and make, the controller only connected "after" the trailer was connected to the plug.. But no biggie, it worked great and easy to set up... 717296

Great! No problems at all. Dont have to worry about my brakes working on the fifth wheel. App does not interfere with other important phone operations while traveling.

2014 Audi Q5

After a lot of research I purchased the Curt Echo Trailer Brake. I was looking for a trailer brake controller with a non-permanent installation, one that I could take out of the vehicle when I wasn’t using it. I was a little anxious because I have a European SUV and have read all the stories of the complications that can come with wireless/Bluetooth connections to the controller. After looking around for the best price I found that etrailer.com was competitive, and ultimately I went with them because of their reputation for service. I was not disappointed. My parts arrived sooner than expected and installation was a breeze. The Echo installed without any issues in a matter of minutes and works perfectly with my Audi Q5. And, no permanent fixture screwed into the dash of my SUV. Thanks etrailer. 605706

2018 Chevrolet Silverado

Product works completely as described. Easy to add a controller to ANY vehicle that has a 7 point trailer plug like my 2018 Chevy Silverado (no factory brake controller but has a prewired 7 and 4 point trailer plug) or my 2014 Jeep Grand Cherokee. Trailer is a 2 axle CargoMate. App was a bit hard to find on the AppStore (iphone). Search "Echo" not Curt then it comes up. Set up is quick and easy to modify if necessary with load changes. App does not need to be normally running if you don't need to apply brakes manually. But if you do need to apply brakes, the response is surprisingly fast through the Bluetooth communication. No delay whatsoever. It doesn't interfere with other apps running either. I like to use navigation and stream music from my iphone 8. Only real issue I have with the product is that its not lockable. Very easy for someone who knows what they are looking for to just unplug and run. I parked overnight at a hotel and didn't realize it until the next day. Got lucky that it didn't get stolen, but now I'm aware and take it off when done towing. 588470

Been a year and 1000s of miles of towing ... still working great!

2000 Toyota Camry

Easy to set up and use, even for me who had never used trailer brakes before. Hauled my 10k trailer from Ohio to Idaho and it worked like a champ through the mountains and plains alike. I'm quite happy with it, had no connection issues, could hook up to my headset at the same time even though I have a pretty cheap phone. The app design leaves a bit to be desired, but is simple enough. 655051

I just tried this out today I was amazed as to how easy it was to download the app and to set it up I am glad i decided to go this route as I have 2 vehicles that I want to use to tow my trailer I wound up staying with the default settings as it worked best that way 612554

- C51180

This product has worked very well. I don't have a lot of experience with other brake controllers, but this little guy makes it very easy. There is NO wire installation. I just plug it in to my 7-pin connector then plug my trailer in to this. I connect my phone to it, and we're good to go. It very easy to adjust the settings when I need to. My phone can still connect to the car bluetooth at the same time. I have had nothing but a positive experience with this product. 668430

Toyota Echo

I was pleasantly amazed at how simple the Curt Echo trailer brake controller was to install and use with my camper. Instead of spending a minimum of 8 hours and finding all the necessary accessories for a typical hard wired controller, I just plugged it , synched it and was done. It worked flawlessly on the first trip and I could not have been more pleased. Also, the vehicle I plugged into was not factory wired for towing lights but the Echo still worked without a problem. 655881

- C51180

Be cautious of this unit. It works but has a lag in braking apply and release. Also be aware that the blue ring may not always show your braking force, which makes you question if it is even working. For a blue tooth unit, with no wiring, it works as expected. 2018 f150 669016

2018 Chevrolet Silverado 1500

So far this works. It works and the app does not need to be on as some seem to think. I set up my phone so the app stays active in case I need to use the manual stop. The set up easy and the app is easy to use. Tweeting and adjusting was a breeze as I did it with only 4-5 slow and fast stops. I plan to put 1500 miles on it over the next 3 weeks so if things change I will update. 658190

It still works

2018 Acura MDX

I purchased a 2018 Winnebago View(2017 Mercedes Sprinter chassis) and while it came with a hitch and 7 pin connector, it did not have a brake controller. The camping store tried to install a traditional controller but was unable to. While etrailer has a very nice video on installing a controller on the newer chassis, actually finding a shop to do the installation was difficult. Low and behold, when getting ready to order the parts from etrailer, I came across the Curt controller. I ordered one, received it in three days, it took about 15 minutes to install(from opening the package, downloading the app, pairing to my phone and adjusting the controller). Worked perfectly on a 500 mile trip that weekend. The even better part about the Curt controller is that it should work perfectly on our Acura MDX which likewise came with a hitch and 7 pin connector but no controller. 5 stars for convenience and usage. 597576

So the harness you would want is the part # 3073-P which the gray end will plug into the factory connector on your Jeep and once you cut off the black connector will wire color for color to the wiring of the Spectrum # C51170. At this time (April 2020) there isn't a harness from Curt that fits your Gladiator.

  • Installing Trailer Brake Controller on 2018 Ford Transit T250 with Factory 7-Way
    There is not a factory brake controller plug-in port on your 2018 Ford Transit T250 so in order to install your existing Tekonsha Primus Brake Controller you will need to hardwire it in using the Wiring Kit # 5506. This kit will provide you with the power and ground wires for the brake controller along with the needed circuit breakers. The red wire from the brake controller will then need to be spliced to the cold side of the brake light switch on the Transit. This is the wire that only...

  • Brake Controller Recommendation for 2020 Kia Telluride with 4-Way
    So the easiest to install brake controller that also works really well is the Curt Echo Mobile part # C51180 which is what I recommend for your 2020 Kia Telluride. Basically this just plugs into an active 7-way and once you sync it to your phone it's ready to go. This brake controller is proportional which means it senses the amount of deceleration your tow vehicle is applying and applies the trailer brakes in a relative way. To convert the 4-way to a 7-way so that you can install the...

  • Curt Echo vs Tekonsha Prodigy P2 Brake Controller for 2019 Kia Sorento
    The Curt Echo # C51180 and the Tekonsha Prodigy P2 # 90885 that you're deciding between are both excellent proportional brake controllers but as you mentioned, their installation, operation, and physical design are all quite a bit different. Between the two options I recommend going with the Curt Echo # C51180 for your application because it will offer an easier installation process and its convenient operation is simply better fitted for occasional towing like you plan on doing. Once...

  • 4-Way to 7-Way Adapter Recommendation for Installing Curt Echo Brake Controller
    If your plan was to install a brake controller you'd have to also run the black wire of the 7-Way Adapter part # 30717 to the to the positive post of your vehicle battery as well as the ground you mentioned. The Curt Echo part # C51180 that you referenced needs the black wire to power it and then uses the other signals from the 4-way adapter to tell when the vehicle brakes are on. For a different adapter that comes the extra wire and breaker to activate the needed circuit for the Curt...

  • Can Brake Controller be Installed on a 2020 Tesla Model 3
    It is possible to connect a brake controller to your 2020 Tesla Model 3. Since Tesla doesn't recommend towing with the Model 3 your best option is the Curt Echo # C51180 because it only need the basic lighting functions and 12V power for operation. This connects to your Apple or Android smart device via Bluetooth and that's how you change the settings. I've attached a review video for you to check out. Now to complete your towing setup I recommend using the Stealth Hitches Kit # 391TES317T...

    Thank you for your purchase and I am glad that you liked the Curt Echo Mobile Trailer Brake Controller part # C51180 and Hayes Sway Master Electronic Sway Control System part # HA81775 I recommended.

  • Will the Curt Echo Work On a 2019 Volkswagen Atlas
    In certain cases, some vehicles like your 2019 Volkswagen Atlas do not send a full 12 volts to the trailer connector which then creates an issue for the Curt Echo Mobile Trailer Brake Controller part # C51180. We have not yet had a chance to test this yet therefore, if you want to be sure it will work before you order you can probe the 12 volt power pin in the 1 o'clock position on the 7-way trailer connector to make sure there is a full 12 volts of power, if there is you will be good to...

  • Recommended Trailer Brake Controller for 2016 Audi Q5 TDI
    If they installed the OEM tow package wiring in your 2016 Qudi Q5 TDI, then there should be the connection under your dash for the wiring harness to be a simple plug and play. The Curt Custom Wiring Adapter for Trailer Brake Controllers # C51522 will have the plug for the factory harness and then you can use the Curt Spectrum # C51170. This proportional controller will have a much cleaner look on your dash so it is what I recommend if you have the plug in harness. If you don't have...
