CURT 51180 Echo Mobile is a proportional, Bluetooth trailer brake controller for one or two axles (two to four electric brakes). A triple-axis motion sensor adjusts brake output to the tow vehicle's deceleration rather than using a fixed time delay. It plugs directly between the existing vehicle-side 7-way RV blade socket and trailer 7-way plug, requiring no cutting, splicing or in-cab mounting. Use the CURT Echo smartphone app on a compatible iOS or Android phone to set and monitor braking. The weather-resistant portable module includes a retaining strap and multi-colour status LED. If Bluetooth disconnects, CURT confirms it continues braking with the last programmed settings; reconnect when safe. This is Bluetooth control, not Wi-Fi control. Verify the vehicle's 7-way RV blade connection and trailer brake compatibility before towing.
