Radio retrofit: 1993 Audi 100 (C4 chassis)

[Steve Mills]

I've already done this in a couple C4's. You will need the later front
console, since the Delta and Concert are both wider than the single DIN
Gamma. This also means that you'll lose the cigarette lighter socket that's
to the right of your Gamma. To remedy this, you can also go with a later
rear console that has provisions for a lighter socket (C4's after 95 got EDL
and dropped the diff lock) and you can fit the lighter socket and a B3/B4
diff lock switch in the rear console.

I also have developed some spreadsheets with the pinouts for the various
radio options- let me know if you're interested, and I'll find a way to post
them somewhere because the list won't take attachments.
