I want to replace my stock Volvo HU-803 with an aftermarket double dim nav unit. The car is a 2004 Volvo S60R. I was able to find the double dim adapter for the new stereo but I still have a few questions.
1: Does the 04 S60R have an external amp?
2: Do they make a plug and play wire harness?
3: Will the center channel work?
4: Do they make a controller so I can still use the steering wheel controls?
I think that is it for now. Any help would be greatly appreciated.
