<p>A DAB (digital audio broadcast) interface module (10) for retrofitting a DAB radio functionality to a vehicle audio system head unit (14) which has a CD changer port (16), whereby the DAB interface module may be directly connected to and controlled from the head unit. The DAB interface module (10) includes a translator module (18) and an amplifier module (20). The translator module (18) is configured to receive command information from the head unit (14), translate the information into command information for a DAB radio module (12), and transmit the translated command information to the DAB radio module (12). The amplifier module (20) is configured to: receive an audio signal from the DAB radio module (12), amplify the audio signal into an audio signal for the head unit (14), and transmit the amplified audio signal to the head unit (14). In use, the DAB interface module (10) is connected to the DAB radio module (12) and to the CD changer port (16), which means that a user can control the DAB radio module (12) via the head unit (14). DAB radio module (12) can be integrated into DAB interface module (10) for an all in one solution.</p> |
