Afternoon all, My Bose head unit has developed the common volume fault and my cd changer is borken so i see this as a good opportunity to upgrade. Does anyone have any advice/info on a head unit. I'm not looking at spending alot and would like a MP3 compatible cd player. Would also like it to blend in with the car as much as possible. Just talked to our local Halfords who have advised i need the facia adapters (was aware of this) and i'll also need a wiring adapter at a cost of £44. Thought this was a little steep. Is this correct.? If you could show me some piccies of your aftermarket head units that would be appreciated. It's the 99 A4 on question. Thanks in advance, Rob.
