Towing? There's an app for that. This brake controller connects to your phone with Bluetooth so all your settings are right in your hand. The unit plugs into your 7-way for a one-step installation with no wiring.
Features:
Specs:
Pair with other OneControl systems for convenient control of your trailer in one app!
Quick Tip: The Bluetooth PIN for initially pairing to your smart device is located in the quick reference guide!
Note: If Bluetooth connection is lost, the brake controller will continue to function safely, using the most recently programmed settings. This brake controller is not compatible, but will not interfere, with Apple CarPlay or Android Auto.
The Curt Echo is unique for its plug-and-play installation. With no wiring or permanent installation, setting up the Echo is a breeze.
The main unit plugs into the 7-way at the rear of your Dodge Van and then the 7-way trailer connector plugs into it. Use the included strap, found inside the cap, to secure the Echo in place. It will help ensure a constant connection between Dodge Van and trailer.
That done, download the OneControl app on your Apple or Android smartphone and wirelessly pair the unit to your phone via Bluetooth, following the in-app instructions. It should take about 5 seconds for them to pair. Once paired, the LED light on the unit will turn a solid blue. Plug in your trailer's 7-way and let the whole system calibrate for another 5 seconds. When the LED turns green, configure your desired trailer brake settings in the app and save it as a profile. Then you're ready to tow!
Note: If you don't already have a 7-way plug at the back of your Dodge Van, check out our exclusive 7-way upgrade kit for brake controller installation (ETBC7L - sold separately).
Besides the crazy-easy installation, the Echo is unique for giving you control of your towing through your smartphone. You can set the maximum braking output, adjust the braking sensitivity, apply the manual override - all from the OneControl app.
Completely wireless, the Echo connects to the app via Bluetooth. You can save multiple towing profiles in the app, a big plus if you have a fleet and want to be able to just select a pre-set configuration and get towing. And don't worry; after you've downloaded the app, you don't need to have data on to use the app with the brake controller. You'll be able to receive calls and texts and access your other apps.
OneControl App
Simple, intuitive, and user-friendly, the OneControl App makes it wicked easy to manage your settings and control your trailer.
1. Manual Override
This big orange button in the middle of the app is your manual override. Press and hold the button, and the brake controller will smoothly apply the trailer brakes without applying your Dodge Van's brakes. This is perfect for stopping sway or controlling your trailer's momentum in an emergency.
Quick tip: Put manual override right at your fingertips by adding this button (C83HR - sold separately) to your dash. The app must be running for the button to work, but it can be in the background while you use other apps on your phone. The button has an adhesive back and runs on a replaceable battery.
2. Brake Output Indicator
The outer ring gives you a visual indicator of how much power is being applied to the trailer brakes. This is determined by your max output setting.
3. Max Output
Braking output is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop.
To set your maximum braking output, tap this button and increase or decrease using the + and - buttons. You want to set the braking output as high as you can without locking up the brakes.
4. Sensitivity Level
This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the max output level. This is a great adjustment to make when you're towing a heavy load and the trailer will need more umph to bring it to a stop so it doesn't push your Dodge Van forward.
Just like max output, if you need to change your sensitivity level, use the + and - buttons. If your Dodge Van takes too long to come to a stop, increase the setting. If it stops too abruptly, lower the setting. You may also need to adjust the sensitivity based on your own preferences, or when the trailer load or road conditions change.
5. Dodge Van Hazard Lights
If you turn on your Dodge Van's hazard lights, there's a chance the trailer brakes will pulse on and off as the lights flash. Turn this setting on any time you activate your hazard lights to prevent this problem.
Save Multiple Trailer Profiles
Get on the road faster by saving your settings. With the app, you can add and store multiple profiles for both trailers and Dodge Vans so that your preferred settings will be ready to go as soon as you hook up. This is perfect if you own a fleet and don't want to have to reset the controller every time you swap out trucks, trailers, or drivers. You'll have the ideal settings saved and waiting for you. To switch between profiles, just swipe left or right.
If you like the idea of monitoring your trailer from your phone, the other OneControl systems could be a great fit for you.
The Curt True Course (C94VV - sold separately) is an advanced Bluetooth sway control system that automatically triggers the trailer brakes (independent of the Dodge Van's brakes and the brake controller) when it detects dangerous trailer movement. The Curt Tire Linc (C54VV - sold separately) Bluetooth TPMS monitors the temperature and pressure of your trailer tires. All of these systems use the OneControl app so you can manage all of them in the same place on your phone.
The LED indicator light on the top of the plug-in module will show you when the brake controller is connected. You can also check the LED for simple diagnostics when you need to troubleshoot.
Because the Echo mounts outside the Dodge Van, it's designed for maximum weather resistance. The unit is filled with an epoxy resin that seals off the internal components from moisture and the elements. The Echo also has a soft locking tab for connecting to your 7-way plug that reduces vibration and helps ensure a constant connection.
Proportional braking means that your trailer brakes mimic your tow Dodge Van's brakes. If you slam on the brakes in your Dodge Van, your trailer brakes hard; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your Dodge Van's braking. This saves wear and tear on the tires and the brakes on both your Dodge Van and trailer.
The Echo uses an internal 3-axis accelerometer to sense how your Dodge Van is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow Dodge Van and activates the trailer's brakes to ensure that your trailer slows at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

If the trailer brakes are holding a bit longer than the car brakes, it sounds like the sensitivity is a bit too high. I suggest using the app to reduce the sensitivity level and then testing it to see how the brakes react.

Still the same issues a year on. The iPad App requires Location Services. Why is this necessary for a brake controller? Yes, I know the app does other things, but it does not need Location Services for the Brake Controller portion of the app. Additionally, it still grabs too hard when pressing the brake in the vehicle no matter what setting I have the app set to, its quite annoying. The brake curve for the controller is not designed well.

That does sound frustrating, Chris. When the Echo is plugged in your vehicle could think that there is a trailer plugged in since the Echo would be pulling a little bit of power to turn on which can cause some issues for sensors because they are expecting a trailer to be there. How was the unit not working your your CX90?
