I have a 2000 Beetle that has a radio the same in the pic posted here.
All I did was enter the 4 digit code and the radio came on.
I didn't have to press or turn anything like it said in the manual.
Also apparently there is a serial number on the radio that you can use to get
your 4 digit code. You can actually go online and enter the serial number and get the code.
I hope this helps anyone in the future with the same problem.
Cheers
