Looking to start upgrading. So far I've only gotten the windows tinted, all 7 windows are 30% and it's made a significant differene already in my opinion. My car is a 2001 S60 N/A.

Is it possible to upgrade my rotary style climate control unit to the digital style climate control unit?
Does anyone make a double din stereo dash kit for the S60?
Will the 05-07 headlights fit my car?

I've looked around but couldn't find any answers. Any info or links would help. Thanks in advance....
