My friend has a 2000 V70 SE and I just took out an SC-900 from my '98 V70R. I was wondering if I could put the SC-900 in his. I assume you can. Would there be a difference in sound if I did this. I don't know if he'd want it because the CD3 isn't working, but I wonder if the overal sound quality for the radio would be worth it to do?
