Its plug-and-play design installs between the vehicle and trailer 7-way connector so you can move the unit between vehicles without under-dash wiring. Built with a potted enclosure, secure retention strap and tri-axis sensing, Echo balances durability and reliable proportional braking while pairing with the OneControl Auto app on iOS and Android.\n\n\u003ch3\u003eHow does Echo install and move between vehicles?\u003c\/h3\u003e\n\u003cp\u003eInstallation requires no tools when your vehicle's 7-way supplies +12V, ground and turn signals. Echo plugs into the vehicle connector first, pairs with your phone through the OneControl Auto app, then you attach the trailer—the whole process is designed for quick transfer between tow vehicles.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePlug Echo into any industry-standard 7-way RV blade socket.\u003c\/li\u003e\n  \u003cli\u003eNo under-dash wiring needed if the 7-way provides power and ground.\u003c\/li\u003e\n  \u003cli\u003eSafety strap and locking tab secure the connection in the vehicle socket.\u003c\/li\u003e\n  \u003cli\u003ePair and configure through the OneControl Auto app on iOS 14+ or Android 9+.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat braking performance and compatibility can I expect?\u003c\/h3\u003e\n\u003cp\u003eEcho uses a tri-axis accelerometer for proportional braking that adapts on hills and varying loads.

It suits trailers with one or two axles and drivers who want proportional braking without installing a permanent under-dash unit. If you rely on a factory brake controller, note it will not operate while Echo is installed, and some vehicles require tow\/haul mode or trailer detection for 7-way power activation.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will Echo work with my vehicle's ABS or cruise control?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — Echo is compatible with ABS and cruise control systems and designed to operate alongside them.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How many trailer brakes can Echo control?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Echo supports trailers with one to two axles, controlling 2–4 trailer brakes.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"CURT","offers":[{"title":"Default Title","offer_id":55172488692055,"sku":"B07JQ99SDD","price":351.72,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/curt-echo-front-view-plugged-7-way.jpg?v=1790451189","url":"https:\/\/britishgarage.co.uk\/products\/curt-bluetooth-mobile-trailer-brake-controller-7-way-1-2-axles-plug-and-play-smartphone-proportional-braking","provider":"British Garage","version":"1.0","type":"link"}
