Bulky brake boxes don’t belong in the driver’s knee space. The Curt Echo Under-Dash Bluetooth Brake Controller keeps things tidy by mounting a 3-3/8" long x 3" wide x 7/8" thick control unit out of sight beneath the dash. Everything you need is inside the box—no knobs or displays sticking out. With the plug-and-play harness and included adhesive pad and zip ties, setup stays simple, clean, and clutter-free.

No extra hardware crowding your dash—your smartphone becomes the control center. Through Bluetooth connection and the OneControl app, you handle brake output, sensitivity, and even manual override right from your screen. The app works without needing cell data once paired, supports both Apple (5.0 and newer) and Android (4.3 and newer), and even stores multiple trailer profiles so you can switch between setups fast.


Rough stops and jerky pulls disappear with proportional braking. The built-in 3-axis accelerometer senses how hard the tow vehicle slows and matches the trailer’s braking power accordingly. It works with 1 to 4 axles (8 brake assemblies) and supports electric trailer brakes for steady, even deceleration every time.
Traditional controllers mean cutting wires or awkward mounting angles. Here, a custom connector plugs directly into the factory port under the dash—no hardwiring needed. Once it’s connected, pair your phone via Bluetooth, wait for the LED to turn solid blue, plug in your trailer’s 7-way, and you’re ready to tow after a quick calibration. The system automatically sets itself up at any mounting angle for accurate braking.

Smart safeguards like reverse polarity and short-circuit protection keep wiring safe from damage. Diagnostic LEDs on the unit make troubleshooting simple at a glance. Even if Bluetooth drops out mid-trip, the controller keeps braking normally using your last saved settings—so you stay in control wherever you go.

hooked right up and not any problems. 2013 F250 connectors were behind the coin

Still 5 stars, lots of trips including a long tow of over 5000 miles. Consistently worked flawlessly. Mild annoyance that they changed the app but once I learned how the new app worked it continues to function flawlessly.

I reached out to Curt about the problems with the new app. They advised that the new app runs the same as the old app it has to run in the foreground unless they are using the button which is the same as the old app. They wanted to know if you were having trouble getting past that screen. Which type of cell phone do you have and which IOS are you using?
