A Bluetooth® brake controller is a wireless device that connects your tow vehicle to your trailer’s electric brakes, allowing you to manage brake force through an app on your smartphone.

Traditional brake controllers are hardwired into your vehicle’s dash, requiring a physical wiring connection, routed wiring harnesses between the trailer and interface, and sometimes drilling and a professional installation. Bluetooth® brake controllers skip the hassle. They communicate wirelessly with your phone and plug directly into your vehicle’s 7-way trailer socket or mount discreetly under the dash or frame, depending on the model.

Benefits include:

• No wiring or dash modifications
• Easy-to-use mobile control
• Adjustable settings for brake gain, sensitivity, and manual braking
• Portability between vehicles (in some models)

This modern alternative is ideal for RVers who want quick setup, flexibility, and clean installs.

CURT offers three models in its Echo series, each tailored to different preferences and installation styles. Whether you're a weekend camper or a full-time traveler, there’s an Echo solution designed to fit your needs

This plug-and-play brake controller connects directly to your 7-way trailer wiring port. It's fully portable and requires no tools or permanent installation. Just plug it in, pair it with your phone using the OneControl® Auto app, and you're ready to go.

Key features:

• Controls up to 2 axles (4 trailer brakes)
• Perfect for users who tow with multiple vehicles
• Store settings for repeat use
• Weather-resistant casing for exterior plug-in

Designed for drivers who want a cleaner, hidden installation, the Echo under-dash mounts behind the dash using a vehicle-specific quick-plug harness. It leaves your dash uncluttered while offering full wireless control.

Key features:

• Controls up to 4 axles (8 trailer brakes)
• Mounts out of sight for a factory look
• Great for RVers with dedicated tow vehicles

Built for durability and long-term use, the Echo in-line model installs directly into the wiring harness near the rear of the vehicle, underneath the frame or behind the bumper. It’s completely hidden, weatherproof, and ideal for harsh towing environments.

Key features:

• Waterproof housing for under-vehicle installs
• Controls up to 4 axles (8 brakes)
• LED diagnostics and calibration
• Retains settings without needing your phone once connected

Bluetooth® brake controllers offer convenience and control, but CURT Echo takes it a step further. Here’s why this system has become a go-to choice for RV owners across the country:

With Echo Mobile or in-line, there’s no need to drill into your dash or install knobs or switches. The smartphone app handles everything, making your cockpit cleaner and more streamlined.

Echo Mobile is completely portable. If you switch between tow vehicles like a truck to an SUV, you can move the controller in seconds. No hardwiring required.

The OneControl Auto app gives you complete control over trailer brake settings. Adjust brake gain, change sensitivity levels, or apply manual brakes right from your phone screen.

All CURT Echo models are equipped with internal memory and a triple-axis accelerometer. If your phone disconnects or loses signal, the brake controller continues operating based on your last settings. Safety is never compromised.

Each model uses real-time vehicle motion to apply trailer brakes smoothly and proportionally (vs. time-based). This reduces brake wear, prevents jerky stops, and improves overall towing comfort.

Towing different trailers? Echo lets you save and switch between multiple profiles in the app. Adjust gain, braking sensitivity, and calibration for each trailer setup.

The OneControl Auto app is available for iOS and Android and acts as your command center for all CURT Echo controllers. Once paired via Bluetooth®, it allows you to:

• Set and adjust brake gain
• Fine-tune braking sensitivity
• Use a manual override function (emergency braking)
• Create and save multiple trailer profiles
• View diagnostics and error notifications

The interface is user-friendly and designed for quick adjustments without interrupting your drive. Plus, the app updates automatically, so your controller is always running the latest software.

Here’s a quick comparison to help you decide:

Each model offers the same intuitive app experience and proportional braking, but your installation preferences and vehicle usage will determine the best fit.

Customers consistently praise the CURT Echo for its simplicity, reliability, and flexibility. Many users highlight how easy it is to install compared to traditional brake controllers. RVers appreciate that the CURT Echo doesn’t require modifying their dash or spending hours on a complicated setup. The plug-and-play design, especially in the Echo Mobile model, makes it a favorite among those who tow with multiple vehicles or want to avoid hardwiring.

In addition to ease of use, the Echo receives strong marks for performance. Users report consistent, responsive braking that gives them greater control and confidence, especially during long hauls or in challenging driving conditions. The app’s intuitive interface and real-time diagnostics make it simple to adjust settings and troubleshoot on the go. Whether towing a 5th wheel, travel trailer, or utility hauler, RVers find the Echo a dependable, smart addition to their towing gear.
