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 locking tab for connecting to the 7-way RV blade vehicle socket. This tab helps maintain a strong connection.

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.

    Easy to install and use

    Very easy to use. No cutting into wires and having some controller box in the way while driving. I installed it in the 7 way plug and plugged the trailer connector into that. Worked right away, easy to adjust. It just works well.

    Curt Echo

    I was nervous about trusting my ability to stop our camper when I order the Echo. After my first use i was in love worked well took some time to find the right sensitivity. The only issue i had is when i picked up my camper the left directional did not work was aggravated with the dealership long before i made it to this point so thought blown bulb whatever fix it when I got home. After diagnose that my Echo controller was not sending the signal through, i called curt and they sent me a new no questions asked and have had no problems since.

    Excellent Customer Service

    I purchased the echo for use on a Jeep Wrangler. It has functioned well. We recently purchased a 2019 Ford Ranger. The Echo app seemed to be malfunctioning by constantly applying the brakes. I called Curt where Mark answered the phone and promptly solved the problem. It turns out that some of Ford's new technology sends a constant low voltage signal, which causes this to occur. Curt has improved the product and Mark is sending the updated unit to me. This level of customer service and product development are rare these days. Kudos to Curt for standing behind their products and retaining customers.

    The future of towing

    With the advancement of technology Curt Group has done a great job keeping stride with the demands of clients like myself. The simplicity of using this product is second to none. I can load my grass clippings into my utility trailer and run them to compost on a Saturday morning, and immediately hook up to my boat for some fun on the water. Each trailer settings are store and accessible right at my fingertip. Definitely worth the investment.

    Good product

    Had my 7-way wiring installed by U-Haul and had to use the wireless brake controller. It worked great, right out of the box, after a few adjustments. Haven't used it long term yet.

    Great brake controller

    A nice simple brake controller that works great. Really nice to not have to install something permanent. I would give it 5 stars if it had Apple CarPlay support

    Love this brake controller

    Took a chance on this and absolutely love it. Now every vehicle I own has trailer brakes with 1 controller. It bypasses my trucks old controller so if I want to use the old one or this one, there is no set up. Just plug it in and go.

    Easy install and operation

    I was hesitant but after visiting my local hitch dealer, it has been the best purchase I’ve made in a few years. Didn’t have to mess with any wiring underneath the dashboard. Love it, highly recommend!!
