I would like to upgrade the Audio 10 unit to Audio 20 or similar. There are a number of head units available on e bay but I am concerned to get the correct model. Does any body know which model numbers will fit my car? My local dealer wants Â£800.00 to upgrade!!
Your car seems to accept (at least some version of) Audio 20 and Audio 30 units, APS as an option and also Comand of course. Perhaps if you could narrow down your selection, then the part number checking would be simpler.
At least for Comand retrofit there are a lot of internet pages describing how to do it and which part numbers are needed. Would an Audio 20 give a lot over an Audio 10 anyway? I assume the Audio 30 APS is a bit outdated on navigation capabilities, I guess you can get even a DVD based Comand to your car?
