I have a 2004 A3 2.0TDi
I'm fairly sure my unit is the concert system, not Bose or anything else fancy.
I have searched but not found the exact answer I'm after. I want to fit either an AUX input, or a way in which I can play music through my iPhone as cheap as possible, obviously without changing headunit.
I have looked on eBay and come across various kits, but wondered whether they're plug n' play, do they require alot of work, will they work with my particular headunit etc?
Any help will be greatly appreciated, thanks!
