CD Player Error
 

I have a 2005 SC70 with an HU-650. The CD player rejects all CD's and says "Error" on the screen. I have read that this is relatively common with this unit. My question, if I buy a replacement unit (from E-bay), can I simply remove my existing unit and plug in the replacement, or must there be some programming done by Volvo to accomplish this task? Any advice or experience is appreciated.
