Description

The CURT Echo mobile trailer brake controller is a Bluetooth enabled device that wirelessly connects to your smartphone and allows you to control and monitor all trailer brake activity right from your device. It features a simple, plug-and-play installation, a portable design to easily switch between vehicles and a highly durable construction to outlast the elements. The Echo brake controller brings your towing experience into the modern age. Powered by Bluetooth, it wirelessly connects to your smartphone without any extra wiring harnesses or modules required. Simply download the Smart Control app on your Apple iOS or Android OS device, plug the Echo into your vehicle and you're ready to start towing. The app allows you to create multiple vehicle-trailer profiles for different towing situations. Installing the Echo trailer brake controller is truly a plug-and-play experience. It is designed to insert in between the vehicle-trailer wiring connection and is compatible with any industry-standard 7-way RV blade plug. This design also allows the Echo to be easily transferred between vehicles, making it perfect for fleet vehicles or multiple-vehicle owners. The Echo mobile trailer brake controller is built to withstand the outdoor elements, whether you're towing through rain, snow or sunshine. It features a potted enclosure. This means the interior of the Echo is filled with an epoxy resin that covers the internal electronics and seals them off from dirt and moisture. This promotes long-lasting durability and also helps reduce vibration. To further enhance the connection, the connector port of the Echo is equipped with a retention strap and locking tab to firmly seat in the 7-way vehicle socket. The CURT Echo mobile brake controller operates with a tri-axis circuit for smooth stops going up or down a hill, and it is able to operate up to two to four trailer brakes at a time (one to two axles). It is also compatible with cruise control and ABS brakes.

    • It works great - reliably, and with no fussing around
I use this controller with a Mercedes GL 350, an iPhone 13 Pro, and a Cargo Express 14 foot trailer. I got this product because I did not want to find space for a big controller interface box in my fairly compact under-dash space - partly because I am 6'7" tall and don't want to loose any leg clearance. The setup is just as simple as the YouTube instructional videos say it is. The controller and the Bluetooth app work very reliably while driving. The app is designed to keep the program running without going to sleep (with or without aux power), and it allows you to run the app in the background while you use (and switch back and forth with) a navigation app like Maps or Google maps. Once it has been set up and a profile initiated, it is possible to use the controller without the Bluetooth app (or if you loose connection or shut the app off) although it will just run on the settings of the last used profile. I really don't mess around with the settings while driving, so this is not an issue, although you do loose the ability to command the brakes ON while driving without applying the vehicle brakes just by using the controller (but the brakes still do come on just fine when you hit the vehicle brakes). (Apparently manual activation of just the trailer brakes alone can be used to correct an oversteer slide by the towing vehicle, but I have not had a chance to try that yet - fortunately.) I have only 2 minor complaints. First, the controller is kind of long - so when it is installed on my vehicle (with a low mounted and downward pointing trailer wiring plug) the plug and the trailer connection wire get close to the ground and I need to use a bungie cord to insure ground clearance. Also it is vulnerable to missteps as with loading the vehicle or from dogs climbing into the back of your vehicle. And second, for some reason the fit between the controller and the trailer wiring plug is not great - it needs a lot of force to connect (even with WD-40), it is hard to get the retainer latch to engage, and it always seems a little insecure - but it does work - no failures in my experience. Maybe thats just a problem with the Cargo Express plug - maybe not. But bottom line - this is a great product, it works great, and it very nicely gets around the awkwardness of a dash or under dash mounted brake controller. ... show more

    • Super nice product
I just drove 900 miles using this brake controller and it worked great (really great). My wife got a new 2025 RAV4 and didn't want me to drill any holes or add any brake controller under the dash. I just used a cellphone holder and ran the app the entire way and the brake controller software on the cellphone ran continuously without my screen every going blank. My biggest fear was it would come out of the brake receiver and break but it holds tightly. I didn't need to use any tie straps or Velcro to secure it. The blue tooth connection was solid and it never dropped signal. The PIN code to connect to your phone is inside the lid of the unit. I normally don't review things unless it really like it or really hate something. I'd definitely recommend this item. ... show more

    • After less than a year of use, we replaced our Curt Echo. It did not last and did not do its job.
I purchased the Curt Echo Wireless Break Control less than a year ago. It wasn't cheap, but the reviews were good. I just replaced it with a wired system because the Curt unit completely failed. There were 2 main issues. Because the unit is long and heavy at the end, it can loosen up. The velcro strap that came with it is completely useless. I ended up using bungee cords to hold it in place, but it still loosened up traveling over rough roads or in heavy traffic. Driving, I would realize that I had no lights on our trailer, and would have to pull over to push the unit in to stay firmly connected. The final issue was break sensitivity. I would end up setting my app at a sensitivity of 1, and the the breaks would still grab. I tried various settings, and it was worse. The last straw was when I was stuck in heavy traffic and the breaks were jumping- grabbing so hard we had to pull to the shoulder of the highway where I removed the unit. Once I removed the unit, everything was fine. I drove in stop-and-go congestion with no breaks on our trailer in order to get home. When I got home, I installed a break controller, which works perfectly. This was not as easy to install, but the new unit was less expensive and does the job I need it to do. (For the record, I drive a Honda Pilot and we pull a ultra-light 17' fiberglass Casita camper.) ... show more

    • Does what it says, but there are some flaws.
This is an easy substitution for the more common interior mounted-dash brake control. You will need a 7-pin connector that has the same light/turns/signal and brake functions. In addition, a 30amp 12v Power lead will be required from the alternator or battery for the unit to draw power. Pros: Flexibility to move across various tow vehicle and trailer solutions. App very simple to use, pretty intuitive once you've setup the initial bluetooth connection. Cons: Has the possibility to wiggle free from either the 7-pin vehicle mount, or from the 7-pin trailer plug. The retainer strap to wrap around the unit/7-pin protective door uses a rubber stretch hole over a round pin type of secure method. The problem I have is that the hard round pin is part of the stretch strap, and does not easily allow the hole to lock to the pin. In my case, the hard pin literally pulled itself from its anchor. I am looking at using a velcro computer cable strap to become the "lock" band. It's plastic, can adjust to a proper length and will grip better than a stretchable rubber pin (YMMV). Overall - this works well enough and is a cheaper solution that doesn't require any mechanical work to use the controller itself. ... show more

    • Easy on brakes
Works perfect with no connection issues. Can adjust settings on phone and save a profile. Heard some had that issue but profile saves settings in case that happens the controller will still work. I highly recommend for those that don't have factory brake control in truck. Instructions are easy to follow. Price was half of dealeship. ... show more
