Easy to install
Designed to be self-fit, you’ll find both Highway 400 and 600 easy to install in your vehicle. In most cases you won’t even need any tools, with just a few simple steps you’ll be up and running.
Our latest Highway adapters also work with your existing audio system using a simple aux-in cable or by transmitting over an unused FM frequency. Consisting of a sleek wireless controller that can be fixed just about anywhere, and a discreet windscreen antenna, there’s never been an easier way to enjoy digital radio, music from your phone, and hands-free calling in your car.
