Echo® FAQs

1. What happens if my phone dies or the Bluetooth connection is lost?

Once Echo® is configured, the unit will stay on the last saved setting even if the phone dies or the Bluetooth connection is lost. If Bluetooth is disconnected, the unit will continue to function on the last saved setting, but the manual override function will be lost.

2. How does Echo® know when to brake?

The Echo® applies the trailer brakes when the vehicle's brake pedal is pressed and its triple-axis accelerometer senses stopping motion.

3. If I already have a brake controller installed and I want to upgrade to Echo®, do I need to disconnect and remove the existing brake controller?

If a functioning 12V 7-way is installed on your vehicle, Echo® will override an existing brake controller unit. There is no technical need to uninstall a hard-wired unit.

4. How far does the Bluetooth signal reach?

The Echo® brake controller is designed to provide Bluetooth connection up to 50 ft. without obstruction. This may also be limited by the Bluetooth signal strength of your phone.

5. Will my screen stay on while using the app?

Yes, the app will prevent the phone screen from going into sleep mode. If you'd prefer that your phone be in sleep mode, you can turn off the screen. However, as mentioned under question 1, you will lose the manual override function.

6. Can anyone hack into my Echo® via Bluetooth?

No, you're only able to connect to the Echo® unit using the Smart Control app and by entering the pin stored under the cap or within the installation instructions.

7. Will the app work with my phone?

The Echo® Smart Control app is compatible with Apple IOS 5 or higher and Android 4.3 or higher.

CURT Spectrum™ brake controller push-button rotary knob

Simple, powerful knob

When installed on the dash of your vehicle, Spectrum™ is virtually undetectable as a brake controller. This is because it integrates so seamlessly with the factory controls.

The 2" rotary knob is simple but powerful. It features a dial and push-button operation to control all trailer brake activity. It is also equipped with 10 tri-color LEDs that change and ramp up to indicate various conditions and settings.

Smooth, responsive operation

For responsive braking and safe stops, Spectrum™ is equipped with a tri-axis circuit, making it highly sensitive to the movements of your vehicle.

The computer module detects velocity going up or down a hill and applies the precise amount of brake power needed to bring your vehicle and trailer to a smooth stop. It also features a manual override button for added functionality.

CURT Discovery™ brake controller operation

Discovery™ time-delay brake controller

Unlike the brake controls listed above, Discovery™ is a time-based brake controller unit. Instead of a motion-sensing circuit, it applies an increasing amount of brake pressure over time. This pressure is adjustable from the interface and provides safe, effective stops for the vehicle and trailer.

Discovery™ features a digital, numerical display and has simple controls for easy adjustment.

Venturer™ time-delay brake controller

Like Discovery™, Venturer™ is also a time-based brake controller. It is simple but effective in bringing the vehicle and trailer to a safe stop, increasing the amount of brake pressure as the driver applies the brake pedal.

Venturer™ comes with a basic LED display that ramps up to show braking conditions and settings.
