Installing an Aux Input Adapter

Model: Audi A4 B7 - Years 2004-2008
Part: Accessory kit

To install the Aux output adapter to the original car radio, first, you need to remove the radio itself: for this operation, you will need the appropriate extraction keys to insert into the four slots located at the corners of the radio, with the notch facing inward. Once the keys are inserted, press until you release the locking springs and pull the radio from its slot. At this point, disconnect the blue connector, install the adapter by bypassing with the provided wiring, and route the Aux input cable, for example, into the glove compartment. Before reattaching the radio, configure the adapter and then check the device's functionality.
