The Echo™ brake control 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 is featured 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. 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 is completely non invasive. It also features automatic calibration to help eliminate setup requirements. The Echo™ trailer brake controller features 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 ideal for commercial fleets. Because the Echo™ trailer brake controller is made to be outside the vehicle, we engineered it for maximum weather resistance.
