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

    • Been using for 5 years, works well
Been using for 5 years on Airstream camper, works well. Had to buy new one when I misplaced the old. Handy adjustment with cell phone. You will need a direct line to the Aux port on your 7 way connector wired to the car battery with a 30 amp breaker in line. 10 gauge stranded is recommended. It is still much easier than a wired in brake controller, and it is easily movable to other vehicles. Hold your phone very close to device when first connecting Bluetooth. ... show more

    • Easy to Install and it Worked Beautifully After Initial App Discovery/Pairing on S23 Problem
The app is pretty good but seemed to be picky on my Samsung Galaxy S23. Ended up running the app on a different phone to discover and configure the Echo. Operation was good but frequently lost Bluetooth connectivity with the phone. This didn't concern me because the controller works autonomously from the tow vehicle brake activation signal and the accelerometer sensor readings inside the Echo. Towing a 6000 lb tandem axel 22 foot camper with my 2011 F-150 felt very solid and reassuring with the maximum setting of 80 and a sensitivity setting of 7. The Echo simply worked. When Bluetooth was connected, seeing the reassuring circular bar-graph around the emergency trailer activation button was nice. I'm certain that putting the phone up higher and not sitting on the seat would help greatly and is recommended. I like not having the inconsistencies of an in-cab 3rd party brake controller and having that bump under the dash to hit my knee on. The Echo is completely outside at the 7-way trailer connector. It does protrude quite a bit and recommend just making sure it doesn't get in the way of anything as you tow and turn the trailer. It is quite a bit more money than an in-cab controller you need to install (plus the specific wiring harness for your vehicle). But for the ease of installation and reliable operation I'd pick this over an in-cab wired controller. The only gotcha seems to be getting the phone app permissions right and getting the app to recognize and pair with the Echo which is all done in the app. I've had issues with other apps on this Galaxy S23 which doesn't make it better, but attests to some possible compatibility issues that hopefully get addressed in future app updates. ... 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
