iv just put this stereo in my mk4 golf, it is a v6 4motion 2000 plate
but every time i turn the car off and take the key out the clock goes back to 00:00
and the screen goes back to the original screen
i can not stop it doing this, i have tried over and over again
is it broke or have i done something wrong, it just does not remember the settings iv put it on
any advice please cheers
