[ba] AUDI 100CS Radio

[Buchholz, Steven]

... I think I would advise the opposite approach ... use a voltmeter and
check to see if you have +12 and ground supplied.  To me there is a lot more
risk of major damage trying to directly wire to the battery ...

The other thing I know is that failure of the on/off switch on the deck
itself ...
