'Double-DIN' head unit options

[ADB]

Hello. In my newly purchased (B6) A4 Avant, it has the usual 'double-DIN' CD/tape player. Whilst I'm sure it was the height of technology in 2003, it's a bit 'old hat' now and I'd like to replace it with a unit that has Android/MP3/Bluetooth functionality. I've seen this head unit at Halfords for a good price:

Kenwood

Now, would it fit my car, or does anyone have this model in their A4? Or does anyone know of a better/cheaper alternative? 

Many thanks ;)

You should be able to get the adapter leads for the head unit and any brackets from Halfords to get it to fit your car but not sure what functionality you will lose by changing it.

You could also try one of these as another member in the A6 section has gone for one as an alternative to play music through the standard system
