I purchased the Volvo Navigation system for my 2001 XC and have been extremely impressed with it. However, I did have one beef and am still looking for resolution. The nav. system requires a cd changer-type component to be installed in the rear driver-side cargo area - the same place the Volvo music CD change would go. This requires a new interior side panel to accomodate access. The cargo space is reduced by about 3 inches with this new panel. One thing that the dealer could not find a replacement part for was the factory carpeted cargo mat. The original no longer fits with the new panel. I've looked on every Volvo lot for V70 or XC with a factory installed CD changer or Nav system to see if the cargo mat has a part number on it. No luck. If anyone can help, I'd appreciate it. I have pictures of the before and after if anyone is interested.
