Audio Systems: New stereo for Volvo, volvo xc 70, volvo radio

Question
I have checked with a reputable stereo selling company and they do not have my car on file.  Will the units that fit a 2002 Volvo V70 also fit a 2002 Volvo XC 70?  I also want a stereo with Ipod adpater, but I do not want to lose the functionality of my steering wheel controls.  Is this possible when switching from a stock head to an aftermarket?

Answer
yes that is correct  but why you want to replace the factory radio
that is a good head unit and looks good on the dash
also your factory radio will control any ipod with the correct cable

the only volvo radio that can not do that is the volvo hu650
if you need the ipod cable call this people
