WARNING: Cancer and Reproductive Harm -

The Echo® mobile trailer brake controller is truly a brake control for the modern age. It plugs into your vehicle and wirelessly connects to your smartphone, allowing you to control and monitor all trailer brake activity right from your own device. It comes with a customizable app for Apple or Android phones, a portable design to easily switch between vehicle-trailer combinations and a durable, weather-resistant construction.

Most things in this day and age can be accessed or controlled from a smartphone. With the Echo®, that includes your trailer brakes. Echo® is powered by a Bluetooth enabled system that connects right to your smartphone. Your phone becomes the brake control monitoring unit in the cab of your vehicle. There is no need for extra modules, controls, buttons or knobs.

The Echo® mobile trailer brake controller has one of the easiest installations in the industry. It simply plugs into the standard 7-way RV blade socket at the rear of your vehicle and provides a socket to plug in the trailer harness. It Ts into the connection, going between the vehicle and trailer plugs, and it is completely non-invasive. It also features automatic calibration to help eliminate setup requirements.

The Echo® trailer brake controller comes with a custom-designed app that can be downloaded for iOS or Android OS phones. With this app, the wireless brake control is able to connect to your smartphone and display brake control settings and activity. It also sends you status updates and allows you to receive incoming calls while the app is running. Note: If Bluetooth connection is lost, the brake controller will continue to function safely, using the most recently programmed settings.

With its compact design and simple, plug-and-play installation, the Echo® is extremely portable. You can easily transfer it between vehicles and use it with multiple trailers, as long as the vehicle and trailer have a 7-way RV blade connector. The Echo® Smart Control app allows you to store multiple vehicle-trailer profiles, making ideal for commercial fleets.

Because the Echo® mobile trailer brake controller is made to be outside the vehicle, we engineered it for maximum weather resistance. It is constructed with a potted enclosure, meaning the inside of the unit is filled with an epoxy resin that seals off the internal components from moisture and the elements. This ensures long-lasting operation in spite of rain, snow, dirt, mud and more. The Echo® also has a retention strap and locking tab for connecting to the 7-way RV blade vehicle socket. The strap and tab help maintain a strong connection, keeping the unit firmly installed.

The Echo® mobile brake controller operates using a triple-axis motion-sensing accelerometer -- an integrated circuit that produces smooth, safe stops every time. It is compatible with two to four trailer brakes (one to two axles) and can be used with low-voltage or PWM wiring systems. Echo® is also compatible with cruise control and ABS brakes and has built-in reverse-polarity protection and short-circuit protection. It is backed by a limited lifetime warranty.

    Product great. New app not so.

    Very happy w performance until recent mandatory upgrade from EchoSmart app to OneControl Auto app. Using new app, cannot adjust settings so as to eliminate hard clunking when braking at low speeds

    Works Great, Install hiccup

    The install had a interference. My Jeep GC 7pin connector is in line with the antisway brake ball. The emergency switch and anti sway had to be switched sides on my camper. Also used a SS zip tie in addition to rubber strap! WORKS GREAT!

    Works well

    Install on a 2019 F150 was a little tricky. Would not register a trailer connected so there was no power to the controller for the setup. Needs the brake pedal held down until display says trailer connected. Then install went as described. Very nice.

    Echo improvements

    I think it will work great for my needs. Set up was very easy. Some improvements are needed. Move the led light as far back as possible. Min is covered by the seven way lid hard to see. Improve the strap. I use an elastic Velcro strap as backup. Should not have to come up with a backup strap on my own. Expected something better at his price. Thanks

    Brake control

    I used this for my second time and it works great. I like the easy attachment and the brakes work for me with it. I do keep black tape to put around the close lid and control with two to Three rounds. I was not sure about the rubber strap not coming loss. Works great and time will tell.

    Echo is great, if...

    I received an Echo with the purchase of my small travel trailer. I really love it and depend on it. I did have a bug, which I figured out over time. I have a Battery which powers my Dash Cameras. The small mobile battery is also bluetooth. For some reason, if the Dash Cam battery is on and connected, it interferes with the Curt Echo, and would get Echo App Warning Messages "Trailer has become disconnected from the tow vehicle!!!". This would pop up every time I applied the brakes. Then I powered down the battery and the dash cams, and I never got an Echo warning again. Once I figured this out, I became confident in using the Curt Echo.

    Easy installation and works great

    Easy to install and program. When braking, I couldn’t tell I pulling a travel trailer with my blazer.

    Echo wireless

    At first I thought that I had a problem. When I apply the brakes I don't see the blue line progress around the orange circle as in the documentation. Tech support said that you won't see it unless I am braking hard. I have to assume that it's working as it should. Set up was super easy. The strap should be replaced with a velcro strap.

    Worked well Android and Apple

    Using on a single axle trailer on a 2019 Terrain. Setup instructions were easy to follow. Would give 5 stars but, the indicator light on the Echo is obscured from easy sight when connected and the button to hold the rubber retaining strap will easily pop out if slightly over stressed.
