Bluetooth-enabled brake controller lets you monitor and control your towing directly from your phone. Create multiple trailer profiles and tweak your settings in the app. Main unit mounts out of sight under your dash.

Specs:
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 under-dash is all about simple use and easy install. With the main unit mounted out of sight beneath the dash, all you need is your smartphone to control the settings on the brake controller. You won't have to worry about banging your knee on a bulky controller, cluttering up your dash, or ruining the sleek look of your interior.
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.
The Echo connects to the app via Bluetooth. You can save multiple trailer 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.
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.
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
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 trailers. 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 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.
You won't be dinging your knee on a bulky brake controller or interfering with your vehicle's lower airbags because the main unit mounts out of sight under your dash. This product comes with an adhesive pad and 4 zip ties to make it easy to mount anywhere. (Just don't zip-tie the box to wiring or cables that can shift as you drive!) Thanks to the 3-axis accelerometer, the main unit can be positioned at any angle. No matter how you install it, the unit will sense the direction of travel and deliver smooth, even braking.
The easiest way to install this brake controller is to get a custom, vehicle-specific adapter (sold separately) that plugs right into both your vehicle and the main unit - no hardwiring required. Otherwise you'll have to get a univeral harness and potentially splice into your wiring.
Note: If a custom brake control wiring adapter is not available for your vehicle, a 30-amp circuit breaker (sold separately) may be required for installation.
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 and save it as a profile. Then you're ready to tow!
The Curt Echo under-dash 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 under-dash 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.

Bluetooth-enabled brake controller lets you monitor and control your towing directly from your phone. Create multiple trailer profiles and tweak your settings in the app. Main unit mounts out of sight under your dash.Do not buy either the Curt Under-Dash or plug-in Wireless brake controllers until Lippert fixes the phone app. I’ve used both happily with the old ECHO Smart Control app. I could use the remote manual button with the phone app not even running. As one would reasonably expect the button talked to the controller directly via Bluetooth. The new OneControl Auto app must be running and in the foreground to use the manual remote! And the most recent version of ECHO Smart Control is non-functional, it just tells you to install OneControl Auto.
This was relatively easy to install under the dash of our 2021 Jeep Grand Cherokee, especially since ours has the factory Trailer Tow Package and therefore an existing pigtail connector ready to connect to the brake controller. The Curt wiring adapter made it super easy to connect the Brake Controller to the vehicle's wiring harness. The controller was easy to calibrate and worked seamlessly while we're towing a rented trailer. We used a dedicated (older) cell phone to operate it while we're towing to avoid any potential interference from other apps rather than using our regular phone on which we receive phone calls texts, etc. This was our first time towing a trailer and this easy-to-use Brake Controller helped make us feel safe and comfortable. Highly recommended.
The Curt Echo is now on my Nissan Armada and works perfectly. It was an easy hookup with the supplied harness and does its job.
Easiest install ever !
Plug and play. App is easy understand and use.
My favorite is with the app and on selected active profile you can see the amount of brake amount is being applied to the trailer when the vehicle brakes are applied. I also install the manual override button. FYI: you don’t need the app on your phone open for the controller or the manual override button to work. Also another nice feature of the manual override button is the size about the size of a quarter, uses a CR2032 battery and the battery level is displayed in the app.
The break controller worked seamlessly. Profiles are easy to set up and it has very reliable Bluetooth connectivity with my phone. Installation was really easy on my Honda Pilot!
Very easy to install. Less than 15 minutes. On a 2023 GMC sierra 1500
Needed a brake controller I could rely on because I was pulling my camper to a site at the top of a 25% grade within a few days. Unit plugged right into the harness for the factory brake controller (with the adapter cable) on my 2014 Ford F-150,and worked perfectly. Bluetooth connectivity works through the app (rather than through the phone's "settings" icon),and connects instantly. I'm very pleased with this product.
Worked great. Helped me to trace down a wiring issue with my wiring on the truck and then worked perfectly and controlled some of the heavier loads and was easy to use.
This unit has a constant draw on the battery and will kill the battery flat in about three days if the vehicle sits. Numerous other users had the same issue. Don’t buy. I will be contacting Curt about this issue.
sOnly have used it once so far and everything worked good
Worked perfect for my 2021 Hyundai Pali sade
I was looking for a trailer brake controller that did not require a permanent mounting to the dash or center console of my 2020 Jeep Grand Cherokee Trailhawk. I initially considered the wireless bluetooth controller from Curt Echo that plugs directly into the 7-pin outlet next to the tow hitch. However, reviews from individuals that tow RV trailers identified that particular option prevents the 12v battery on the trailer from charging off of the TV while connected. This would limit the RV utilization during long trips involving boondocking.
The Curt Echo under-dash controller seems to solve that problem and uses the same user interface as the Curt Echo.
Easy to install and operate; problem solved!
Was not aware this device draws on the battery constantly. I don't daily drive my truck and have had to replace the battery twice in one month due to being drained below the point where they could be recharged. $[XX] later and this controller removed, I've not had any problems with the battery
I really wanted a trailer brake controller that I didn’t have to stick an ugly knob/box hanging off my dash. This was my solution and it works perfectly. Plugged right into my Honda Ridgeline existing plug, and easily connected to the app on my phone. Nice setup.
This brake controller has to be unplugged when not in use or it drains the battery in a few days. I had to have a electrical test done in my vehicle ($XXX). The etrailer tech said the test was done incorrectly. The Chevy dealer claims it was accurate. I’m left with a problem.
This is the old obsolete model of Curt Echo which has to be installed under the dashboard. The newer version, which attaches to the electrical system in the rear of the vehicle, is superior and now preferred by most trailer owners. The above version should be taken off the catalog.
As first time truck and pop-up trailer users, we initially purchased a cheaper brake controller that required drilling the dash. This is a new truck, so we decided to switch and spend more for the Bluetooth. etrailer was easy to work with for a return, and the Bluetooth brake controller is fantastic - so easy to use with our new trailer!
The brake controller video was very helpful. I made my choice, ordered it and received free of confusion. Thanks go to etrailer.
This controller took me literally 15 minutes to install with the required pigtail and my Rubicon with factory towing package installed. When I initially downloaded the app and connected, it actuated and locked the brakes. I simple deleted the app and reinstalled and everything worked normal.
Installed the controller under the dash out of the way. Downloading and setting up the app was easy. I have set a profile for my trailer loaded and empty. This is a nice feature.
The app stays open while driving, so the manual brake button is visible, and easy to access, if needed.
Sherry was extremely friendly and very helpful when I had questions about the correct fit for my truck. She got me the information I needed and took my order and the parts shipped the same day. I was amazed at how fast I got my order.
Easy to install once you dig out its connector from under the dash. H Ave the unit completely hidden.
Easiest install I’ve ever had !!
Still don’t have enough experience to say for sure how it works. But, so far no problems. Sometimes seamless use is the best !!!
It was a very simple install. Only problem I had was getting my fat fingers in the right position to install the adapter harness into place. Took maybe 3 minutes though. Web site said it wasn't compatible with my truck, so I called. After a short wait Jesse came on. He was extremely patient as I explained my problem and had me fixed up in just a few minutes. The shipment arrived 2 days early wich is rare these days. Very pleased for sure.
The instructions are a little confusing. Curt provided an instruction manual that leads you to believe you need additional components to complete the install. It’s a general instruction book and needs to clarify the diagrams aren’t necessarily accurate when buying specific components.

I reached out to Curt about the problems with the new app. They advised that the new app runs the same as the old app it has to run in the foreground unless they are using the button which is the same as the old app. They wanted to know if you were having trouble getting past that screen. Which type of cell phone do you have and which IOS are you using?
