Hi guys and girls, I know there is quite a few threads floating about on RNSE fitting and stuff so first of a I apologise if the answer is out there, I have a had a look and personally couldn't find it. So got a sat nav unit in mind to fit into my A3 S-Line, I've currently got double din cd changer built in and Bose, the sat nav unit I can have fitted so its not a question on how to fit it. The part number of the unit is; PART NO: 8P0 035 193 BX. Just wondering if it will be compatable or if I would have to go for an older sat nav unit? Thanks.
