Towing? There's an app for that. This brake controller connects to your phone with Bluetooth so all your settings are right in your hand. The unit plugs into your 7-way for a one-step installation with no wiring.
Features:
Specs:
Pair with other OneControl systems for convenient control of your trailer in one app!
Quick Tip: The Bluetooth PIN for initially pairing to your smart device is located in the quick reference guide!
Note: If Bluetooth connection is lost, the brake controller will continue to function safely, using the most recently programmed settings. This brake controller is not compatible, but will not interfere, with Apple CarPlay or Android Auto.
The Curt Echo is unique for its plug-and-play installation. With no wiring or permanent installation, setting up the Echo is a breeze.
The main unit plugs into the 7-way at the rear of your Jayco Greyhawk Motorhome and then the 7-way trailer connector plugs into it. Use the included strap, found inside the cap, to secure the Echo in place. It will help ensure a constant connection between Jayco Greyhawk Motorhome 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: If you don't already have a 7-way plug at the back of your Jayco Greyhawk Motorhome, check out our exclusive 7-way upgrade kit for brake controller installation (ETBC7L - sold separately).
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.
OneControl App
Simple, intuitive, and user-friendly, the OneControl App makes it wicked easy to manage your settings and control your trailer.
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 Jayco Greyhawk Motorhome's brakes. This is perfect for stopping sway or controlling your trailer's momentum in an emergency.
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 back and runs on a 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.
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 Jayco Greyhawk Motorhome forward.
Just like max output, if you need to change your sensitivity level, use the + and - buttons. If your Jayco Greyhawk Motorhome 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. Jayco Greyhawk Motorhome Hazard Lights
If you turn on your Jayco Greyhawk Motorhome'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
Get on the road faster by saving your settings. With the app, you can add and store multiple profiles for both trailers and Jayco Greyhawk Motorhomes 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.
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 Jayco Greyhawk Motorhome'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.
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.
Because the Echo mounts outside the Jayco Greyhawk Motorhome, 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 means that your trailer brakes mimic your tow Jayco Greyhawk Motorhome's brakes. If you slam on the brakes in your Jayco Greyhawk Motorhome, your trailer brakes hard; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your Jayco Greyhawk Motorhome's braking. This saves wear and tear on the tires and the brakes on both your Jayco Greyhawk Motorhome and trailer.
The Echo uses an internal 3-axis accelerometer to sense how your Jayco Greyhawk Motorhome is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow Jayco Greyhawk Motorhome 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.

Cannot get the app to work with the controller, after reading the numerous reviews on this controller im not the only one that has had issues with it. It has a very low rating. Should have researched it better before buying it. I’m to the point now of just doing without a brake controller altogether. Now I have a $250.00 paperweight.
Purchased this brake controller as I had a specific trip where I was going to be at the limit of tow capacity for my Toyota Tacoma. It was a 4000 mile round trip. The ease of setup and use has made this controller a standard item whenever I am towing. The additional safety provides me a sense of security and confidence whenever I have even light loads to just haul around town.

Still doing great on light and heavy loads. Friends are always asking about it so I make sure to lock it up when not in use.

Amazing product and APP!
Moved from WV to WY pulling a heavy trailer with a 2016 Chevrolet Colorado. Did not have time or money to install a permanent brake actuator in the cab, but I found this controller online. It works amazingly and did not break the bank to purchase. Definitely recommend!

Glad this worked perfectly for your move. Moving from WV to WY is a big trek through all kinds of tertian. Have you been able to start settling down in to your new home?
No where in the video does it say to enter the 6 didget code under plastic flap where the trailer plugs in, how can that happen? L.D. Grove

I'm not sure which video you are referring to, but we do mention on this page that the Bluetooth PIN for initially pairing to your smart device is located in the quick reference guide. We try to get everything in our videos, but we do occasionally miss things. Did you get it paired and working?
I don't get to use this often, but I love it. I've never had any issues with it and the trailer brakes work just like they would if I had a standard brake controller. Installation can't get any easier and the app works great
I just bought a travel trailer and didn't have the time to wait to get a traditional brake controller installed so I bought this. It was literally a plub and play solution. I set it up via the app on my Ipshone in about 5 minutes. Once plugged in I tested it out by going down the road a few hundred feet. I got the amount of force % brake to apply dialed in. I like the manual control as well. I sued that when going down a hill. You can also adjust the amount of force while in the app..
I bought a new camper, then I needed a new vehicle to tow it. It came without a break controller, and the dealership recommended the Curt Echo wireless brake controller. I have not been disappointed. It works great and was easy to set up and use. The E-trailer company has excellent service and a helpful staff to answer my questions.

So happy to hear that you are lovin' your new Curt Echo so much, Robert! Also, congrats on your new camper too! What did you get?
I have owned the Curt Echo WBC for one year now and have been impressed with the versatility of the product. I use it with multiple trailers and vehicles. My only ding is making sure to provide support for the contoller as it is heavy for the plug in and I'm always concened that it will vibrate out. So far, that has not occured.

The controller remains flawless. As I stated in my first review, my only concern was the heaviness of the plug. I have augmented that by using a large rubber band to keep it ed. So far so good.
I bought this for a 2004 Excursion, using the etrailer search function by vehicle. Even though it shows it fits it doesn’t. The way the factory mounted the trailer plugs there is no room for the controller and the trailer cable. I had to disassemble the hitch bracket to make enough room for it to fit. The other issue is the little strap broke the first time I removed it.
One year in and I have found this device to be an excellent product. I've recommended it to all my RV pals as an easy way to get your tow vehicle set up for brakes. Works every time, never had a problem.
I think this is a neat product. My issue is we have a 36foot motorhome I purchased this for to use. It connects setting in drive way and works from drivers seat. Issue is as soon as you start moving it looses connection. I know it saves the last input but I want the ability to hit the brake button while going down a step grade if trailer was to start swaying.
Worked a described, it is very handy with vehicles that rarely tow or in the case that it would require extensive labor and expense to add one. Easy to plug and play!
Has worked perfectly every trip. Use trailer at least once a month. Never need to worry about installing a brake controller again!
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.

After using it for a year, I still think it is the greatest. I have showed it to a number of others - totally amazed at how simple but versatile it is. Only disappointment is not being able to use it more.
We haven't had an opportunity to try it with our trailer yet. The retention strap was missing when we received it. Ashton at etrailer was very responsive and took care of this issue very promptly.

Thanks to all the team members who helped me solve my brake problems. I love the way that the Autowbrake controller works. Ram could not solve the brake issue. thanks again, Dave
Easy to use. No problems with my braking 3500 lb Casita travel trailer. I like that I didn't have to wore a harness and it's wireless Bluetooth tech.
Towed my 5th wheel over 10,000 miles this summer. The controller worked as advertised with no issues. Very happy with the product.
The Curt Echo Wireless Brake Controller is a great product. Very easy to install and use.
The wireless brake system is extremely easy to program and hook up. You can dial it in to any trailer for not just the power of braking but sensitivity as well. You can program several trailers to the same unit. I have driven about 1500 miles with the wireless brake and do not even feel the 6500 pound trailer when braking. I will be honest, I was apprehensive until I used the unit. But you will appreciate how easy and consistent it is. Love it!
Works amazingly well after the brief learning curve. You just can’t over think the process and do it. What a difference not having to install a brake controller on a new vehicle. I would buy it again.

Still working nicely after cleaning all contact parts for best connection. Hope to use it for many seasons.
So we purchased this Curt Echo a year ago and have used it about 10 times so far. This inexpensive solution has performed very well. On my setup level 5 seems to provide good feel and the travel trailer doesn’t “push” us. I always add a couple zip ties to it just to make sure the device stays secured to the connection. As others have said, you do have to leave the application open on your phone but even if it loses connection the controller continues to work on the last setting. Overall I am very pleased with this brake controller and would purchase this again
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?

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.

Happy after using controller for a year. Tends to lose Bluetooth connection a lot, but the controller continues to work on previous settings, so that’s not a problem. After a few tweaks, I didn’t need to change anything. Each time I connect it for a trip, it defaults to my last setting.

Love this brake controller no extra switch under my dash or added holes just use your phone.
This product has generally been a successful purchase, with a simple setup process and reliable performance when used with my trailer. It is rated five stars, though it's worth noting that the flap mechanism is somewhat flimsy; it broke after just a few uses. Despite this defect, the overall performance of the unit remains unaffected.

I will admit to not being a fan of this controller as I prefer to use my phone as a phone and I have heard people say there were issues with the app. Guessing you have probably done this already, but try them one more time just to make sure. -Check Echo LED status for power. -Input PIN from label or quick reference card. Enable Bluetooth or grant permissions. Check smartphone compatibility. -Select trailer profile, tap the Echo device name, then tap the trash can icon to remove. In OS Settings, go to Bluetooth connections and 'forget the device'. If none of that works still, let me know and I can get a return label sent out to you for a full credit. I saw you had previously returned a Redarc controller due the hardwiring part of the install, but would you be open to another option?
