Buckle up, turn up the volume, foot down on the accelerator: listening to the radio is part and parcel of driving a car. This is clearly apparent in the latest generation of vehicles where, despite their increasingly smart communication and entertainment systems, the emphasis is still on radio and audio. Apart from linear services on FM, DAB+ and IP streaming, contemporary vehicles also offer access to non-linear on-demand, podcast and music streaming offerings – partly using manufacturers' own systems, but above all by pairing with smartphones, a feature now standard in all new vehicles. These are the main findings of the study ‘Switch On: In-Car Audio Systems’ published today by the VAUNET German Media Association and the Media Authority of North Rhine-Westphalia.
