Radio on the go
Our in-car audio adapters are the easiest way to upgrade the existing audio system in your car, van or truck without replacing it. Enjoy a wide range of transmitters and DAB digital radio offers in interference-free quality as well as all your favourite music from your mobile phone or tablet or from music services such as Spotify. Whether you're new to digital radio or already enjoying its wide selection and high quality at home, you'll be thrilled to hear music in your car with Highway 400. The DAB digital radio delivers precise digital-quality sound and great content, many of which are only available digitally. Digital radios automatically find all available stations, which you can select by name. All our in-car digital radio adapters also have digital tick approval. So you are well prepared for an upgrade from FM to digital.
Upgrade instead of replace
Highway 400 was developed as an easy-to-install solution for the millions of vehicles worldwide that do not provide digital radio. Our latest Highway adapters can also connect to your existing audio system via a simple aux-in cable or via an unused FM frequency. The adapter consists of an elegant wireless controller that can be mounted virtually anywhere and an unobtrusive windscreen antenna. This makes it easier than ever to listen to digital radio and music from your mobile phone in your car and make hands-free calls.
