i have a 2005 a4 and i am wanting to fit an alpine headunit. I would like to keep the steering controls my alpine has a 3 mm jack plug at the rear of it for them does anyone know the connects code for the product i need..
is this the same sturtyp from t/a?
if so im afraid your on a changover year mate so it could be either of these
ctsd002 (2005 onwards) or ctsd003:2 (upto 2005) be carefull as some suppliers require you to buy a patch lead also
Steering controls go via the canbus system, I assume the jack plug is for an ir remote of some shape or form, you need a direct can connection to accept the steering controls unless alpine have a can to IR unit, which I doubt but hey.
What model alpine is it?
