EXAMPLE OF INSTALLATION AUDI A3
REMOVAL WORK AND PREPARATION:
1. Unlock the OE factory radio with the
unlock tool (No. 17) contained in the
set. You need to insert all four keys.
2. It should be possible to pull out the
radio without applying brute force.
3. To completely remove the OE radio,
all the cables (i.e. main harness,
antenna cable etc.) must be
unplugged on the backside of the
device. Put the radio aside in a safe
place, to protect it from damage.
