Radio wiring question

[Mark R]

#1:  Any illumination circuit which can provide +12V is fine.  From dash
lighting, switch lighting, headlights, etc.  Internally, the head unit is a
relay, so very little amperage.
#2.  VAG had a few different designs in the middle to end of the 1990s with
the amplified antennnas:
a.  There is a separate amp wire.  The is +12V, the antenna base is ground.
b.  The coax itself carries the +12V.  You need an adapter (to which you
wire it as above) with the +12V lead.  Again, base is ground.

I don't have wiring diagrams in front of me at the moment, so I can't
confirm for your car.
