The CURT Echo Mobile brake controller is truly built 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. The unit 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 Mobile, 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 brake control 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's completely non-invasive. Echo 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.

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 app allows you to store multiple vehicle-trailer profiles, making it ideal for commercial fleets.

Because the Echo trailer brake controllers are made to be outside the vehicle, they're engineered for maximum weather resistance. Each unit is constructed with a potted enclosure, meaning the inside 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 debris. The Echo also has a soft locking tab for connecting to the 7-way RV blade plugs. This tab helps reduce vibrations and improves connectivity.

The Echo brake control operates using a triple-axis motion-sensing accelerometer—an integrated circuit that produces smooth, safe stops every time. It's 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.
