Installation of Aftermarket Car Radio

Model: Audi A4 B7 - Years 2004-2008
Part: Car stereo

The first step is to attach the anchoring tabs to the new car radio using the appropriate pre-drilled bracket. Then, slide the car radio into the bracket to verify that it attaches correctly and subsequently detach it using the provided release keys. Also, check the compatibility of the adapter wiring for connecting to the original system, making the necessary connections.
At this point, proceed to remove the original car radio from the vehicle: insert the release keys into the 4 slots located at the corners of the car radio and extract it by disconnecting the connectors attached to it and connecting them to the adapter wiring for the new car radio.
Remove the 2 screws securing the original car radio bracket, insert the adapter frame for the new car radio, and reapply the securing screws.
Insert the support frame and secure it by bending some tabs; connect the adapter wiring connectors to the new car radio and insert it into its bracket until it fully engages; finally, apply the outer frame and perform a functionality check.
