Hi all,

Having read tonnes of threads, I'm not quite getting the full picture, so I need to ask what may be an obvious quesiton to a lot of you!

I want to replace the Concert unit in my 54 plate A4 Avante (new shape). It has the sub-woofer and bose amp in the boot.

I want to fit a pioneer head unit myself, and my questions is, what cabling / adaptors do I need? i.e.

- CAN BUS stalk adaptor. Do I need this as my steering wheel does not have any remote controls? Or is this needed for other inputs such as speed pulse and ignition signal etc?

- ISO adapator. Do I need this for speaker hook up, or does a CAN BUS adaptor include these connections?

- Antenna adaptor. Do I need one of these to hook my head unit up to the factory fitted antenna? On that subject I read the factory fit antenna has poor recepention when fitted to aftermarket units, is this true? If so is an amplifier needed too?

- Facia adaptor. Do I need one of these? If so are the specific to the make/model of car, or the make/model of the replacement head unit?

Thanks in advance!

James
