The Echo® mobile trailer brake controller is truly a brake control for the modern age. It plugs into your vehicle and wirelessly connects to your smartphone, allowing you to control and monitor all trailer brake activity right from your own device. It comes with a customizable app for Apple or Android phones, a portable design to easily switch between vehicle-trailer combinations and a durable, weather-resistant construction.

Most things in this day and age can be accessed or controlled from a smartphone. With the Echo®, that includes your trailer brakes. Echo® is powered by a Bluetooth-enabled system that connects right to your smartphone. Your phone becomes the brake control monitoring unit in the cab of your vehicle. There is no need for extra modules, controls, buttons or knobs.

The Echo® mobile trailer brake controller has one of the easiest installations in the industry. It simply plugs into the standard 7-way RV blade socket at the rear of your vehicle and provides a socket to plug in the trailer harness. It Ts into the connection, going between the vehicle and trailer plugs, and it is completely non-invasive. It also features automatic calibration to help eliminate setup requirements.

The Echo® trailer brake controller comes with a custom-designed app that can be downloaded for iOS or Android OS phones. With this app, the wireless brake control is able to connect to your smartphone and display brake control settings and activity. It also sends you status updates and allows you to receive incoming calls while the app is running. Note: If Bluetooth connection is lost, the brake controller will continue to function safely, using the most recently programmed settings.

With its compact design and simple, plug-and-play installation, the Echo® is extremely portable. You can easily transfer it between vehicles and use it with multiple trailers, as long as the vehicle and trailer have a 7-way RV blade connector. The Echo® Smart Control app allows you to store multiple vehicle-trailer profiles, making ideal for commercial fleets.

Because the Echo® mobile trailer brake controller is made to be outside the vehicle, we engineered it for maximum weather resistance. It is constructed with a potted enclosure, meaning the inside of the unit is filled with an epoxy resin that seals off the internal components from moisture and the elements. This ensures long-lasting operation in spite of rain, snow, dirt, mud and more. The Echo® also has a retention strap and locking tab for connecting to the 7-way RV blade vehicle socket. The strap and tab help maintain a strong connection, keeping the unit firmly installed.

The Echo® mobile brake controller operates using a triple-axis motion-sensing accelerometer -- an integrated circuit that produces smooth, safe stops every time. It is compatible with two to four trailer brakes (one to two axles) and can be used with low-voltage or PWM wiring systems. Echo® is also compatible with cruise control and ABS brakes and has built-in reverse-polarity protection and short-circuit protection. It is backed by a limited lifetime warranty.

    Excellent product, worth the money

    After purchasing the Curt Echo Electronic brake model 51180, I received superlative technical support. Not only is the product of the highest quality and easy to use, the echo staff is equally top notch.

    Love this! So easy to use!

    This product was a real life saver for us. We took a trip out west and needed a trailer brake controller fast. This hooked up so easily and the app is great. Love it!

    easy install & works but ...

    Convenient install and works well but not confident of the connection to 7 way. Used rubber strap once to secure to 7 way and then it would not securely fasten due to the poor design so had to use zip tie. Also trailer 7 way connection is unsure and must be careful it latches well. This is a safety concern.

    Some suggestions

    Worked well. Easy to install. Sometime in my first use, the trailer 7 pin connector to the Echo loosened but did not fall out. The Ipod indicated "Danger" and we fixed the problem. But we only knew this because my wife had the Iphone in her hand. The Echo needs to provide an auditory alert if this happens. If we had stowed your phone, we would not have known we had no trailer breaks. Also at some point we lost the bluetooth connection and we were able to restore the connection easily. I know the unit will store all settings if the connection is lost, but I want to KNOW if the connection is lost. Again an audible would help.

    Echo mobile

    Worked well so far after 6 tows of a travel trailer. Only criticism is the actual hookup isn’t reassuring. I already lost the button insert so I had to use a zip tie. Of course, this is less than ideal. It would a real improvement to make a more robust and secure way of attaching the clasp to the connector. At least supply a few replacement button inserts.

    Echo Blue Tooth Brake Controller

    The controller works flawlessly on our '09 Honda Pilot, towing an E-Pro 19 ft. travel trailer. Only issue is the nub fell out of the band to hold it to the connector on the Pilot. Solid product.

    Easy, portable, versatile

    I needed a brake controller quickly for my gooseneck trailer, this system required no extra wiring. It connected flawlessly to my phone via Bluetooth where I was able to quickly set up a profile and use the device. With the ability to have up to six profiles, I keep this controller in my truck and can pull various trailers with the necessary profiles that I program. If for some reason it loses connectivity with my phone, it continues using the settings of the profile I was using when 1st connected.
