The CURT Echo™ (#51180) is a Bluetooth-enabled, mobile brake control that allows you to control and monitor the activity of your trailer brakes using your smartphone and this downloadable app. The device simply plugs in between the vehicle-trailer 7-way wiring connection and uses Bluetooth to sync with your phone.
Download the Smart Control app to set up your smartphone as the trailer brake control interface for the CURT Echo™. With it you can adjust maximum braking power and sensitivity while towing. It also shows diagnostic information like overload conditions and trailer-disconnect errors. For added control and safety while towing, the Smart Control app provides a button to manually override braking and activate the trailer brakes whenever necessary.
With the compact design and plug-and-play installation of the CURT Echo™, it is a highly portable brake control. It is designed to be easily transferred from one vehicle-trailer combination to another. As such, the app allows you to store up to five user profiles, each with its own personalized settings.
The Smart Control app does not need to be open for the CURT Echo™ mobile brake control to function normally. The app can be closed, and the Echo™ will use the previously selected profile settings to determine maximum braking and brake aggressiveness.

Works with some quirks

I was loathe to splice wire on my new truck so I tried this thing. This has actually worked well for me once I figured out a few things. I have a 2020 Ford Ranger, and if I change the lights to anything other than “auto” setting the trailer lights go kind of … haywire. Once I figured that out it’s worked fine, although it seems to have some issues reconnecting to my phone if it hasn’t been used in a while. It applies the brakes, is easy to adjust on the fly, and the manual activation works well.

I’ve never updated the app since I installed it 1.5 years ago, it seems most people have issues with the later versions. I plan on using it until it doesn’t work before upgrading.

Absolute garbage. Would give it negative stars if able. Worked for a couple trips, updated app, now it always keeps the brakes on rendering it completely useless and dangerous. Now I’m stuck with my camper being unable to move because it keeps the brakes locked on for no reason. Worthless product for the money we spent. Do not buy this, get the old school brake controller wired to your truck.

Just got off the phone with their “customer service” rep, who actually informed he works in the garages and isn’t actually customer service. Worst experience I’ve had talking to someone. I explained the situation that the brakes only get stuck on using this garbage controller, it’s getting electricity fine, etc. He said I had to buy a test light to troubleshoot, wouldn’t explain how that would actually help and instead of honoring the warranty, eventually said he’d do a one time warranty to send a new one but then I was on my own even if it didn’t work. Unreal, do yourself a favor and don’t buy this part.

Works Perfectly

From plugging the device in and connecting to Bluetooth on my phone, it took all of 30 seconds. The device works flawlessly for me without any connectivity issues like others have reported here. While I also think an Apple Car Play App would be awesome, I generally have my navigation on my cars screen and the Echo app on my phone so I’m not knocking a star off for this because it’s my preferred setup. I’m very pleased with how well the device and app work together and am confused by the bad reviews. Perhaps the bad reviews are from defective units? We all know that those that have a gripe are much more likely to write a review than those that are pleased with a product. Consider me an exception, I’m very happy with my purchase.
