Manage Your Trailer from the Palm of Your Hand

Take the helm and command your trailer from the palm of your hand. The OneControl Auto(TM) app works on iOS smartphones and makes it easy to monitor and control your trailer as you tow. Simply connect the app through Bluetooth(R) and control your brake controller while monitoring tire pressure and preventing trailer sway. With OneControl Auto you can make changes while towing in real-time and even create and save profiles for towing specific trailers or payloads.

Compatible with CURT Tire Linc(TM) TPMS Monitor, Echo(TM) Brake Controllers & True Course Auto(TM) Sway Controller

Tire Linc allows you to monitor your tire pressure in real time while on the road and helps you to prevent over or under-inflated tires, which can quickly lead to a dangerous blowout. CURT Echo brake controllers feature Bluetooth(TM) connectivity and allow you to monitor and adjust your brake level output and brake sensitivity from your smartphone. CURT True Course Auto is an automated system that prevents trailer sway when unexpected events occur, such as emergency maneuvers, high wind conditions or when tire blowouts happen.
