My 07 has the standard radio and I wanted to retro fit a sat nav system. Will the B9017 fit my car ? If not thinking of fitting an aftermarket double din, can anyone advise which is the best option. If I go the double din route is there any recommended suppliers for the facia trim and any wiring conversion cables ? I have tried searching the forum but there don't seem to be any how to or example of people that have fitted.
