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.
