Q: I have a 1998 volvo v70R and my sc-900 unit stopped working I noticed that you have sc-901 for sale could you please tell me what is the difference between two and if sc-901 will fit my V70R,

A: Sc–901 is not much different then sc-900, the main difference is that the cd changer is working twice faster than sc-900 changer, some say that the sound quality is also better in sc-901, and yes it fits your 1998 volvo V70R perfectly.
