Overview

The CURT Echo™ (#51180) is a Bluetooth-enabled mobile brake control that allows you to control and monitor your trailer brakes using your smartphone. The device is easy to install and simply plugs in between the vehicle-trailer 7-way wiring connection. Once installed, you can download the Smart Control app to set up your smartphone as the trailer brake control interface for the CURT Echo™. With the app, you can adjust maximum braking power and sensitivity while towing, and it also provides diagnostic information like overload conditions and trailer-disconnect errors.

For added control and safety while towing, the Smart Control app provides a button to manually override braking and activate the trailer brakes whenever necessary. The app also allows you to store up to five user profiles, each with its own personalized settings. This feature makes the CURT Echo™ highly portable and easy to transfer from one vehicle-trailer combination to another.

The Smart Control app does not need to be open for the CURT Echo™ mobile brake control to function normally. The app can be closed, and the Echo™ will use the previously selected profile settings to determine maximum braking and brake aggressiveness. With its compact design and plug-and-play installation, the CURT Echo™ is a convenient and reliable brake control option for any trailer owner.

In summary, the CURT Echo™ is a Bluetooth-enabled mobile brake control that allows you to control and monitor your trailer brakes using your smartphone. The Smart Control app provides a range of features, including the ability to adjust maximum braking power and sensitivity, diagnostic information, and a manual override button for added control and safety. The app also allows you to store up to five user profiles, making the CURT Echo™ highly portable and easy to transfer from one vehicle-trailer combination to another. The device is easy to install and does not require the app to be open for normal operation.
