Hello, I drive a Volvo S60 year 2006 and would like to expand or improve the existing audio system (HU-650). The included radio is simply not enough. No mp3, AUX, etc the following problem: The car has steering wheel remote control, car phone, and nav and parking aid… I think this is all about the double DIN radio and when changing of course I don’t want to lose any of the functions… the phone, this is not really necessary but by no means the Navi, parking aid e or the steering wheel remote control (was everything already in the car, i.e. from Volvo). Is it possible to exchange the radio with another (think about a double DIN with touchscreen) and enjoy the usual comfort? Are adapters (CAN) necessary or is it even possible? How is a conversion like this?
