I'm looking for a 6 cd player for my X5. It has NAV and DSP. Some of the ebay auctions I'm looking at say I'll need a CASBMD cable, others say "fully compatabile with DSP and NAV". I've asked on this board and was told having DSP or not doesn't matter; but if so, why do so many ebay auctions specify whether it works with DSP or not?

Can someone give me a straight answer? Will Alpine CD Changer
P/N 82 11 1 469 404 or BMW CD changer P/N 82 11 0 028 760 work with DSP and NAV as is, or will I need this "CASBMD" cable? If so, where can I get it, and what is involved with hooking up this cable?


This is from one auction:
X3/X5 99-05
Required Cable: See notes (Pre-wired. Left-rear trunk. Except vehicles with GPS. Needs CASBMD cable if vehicle has DSP.)
