It's a 2000 X5, with factory navigation wiring. Upgraded flat pin tuner, DVD MkIV, 16:9 widescreen. CD Changer with live coax cable, so I assume digital DSP since there's no six-pin connector and the CD Changer works. I have a -140 receiver, and these two harnesses: 84 11 0 141 977 and 84 11 0 141 978. But, because it's a coax in the back of the CD changer, I don't think I can keep the CD changer in this setup so the latter cable probably won't get used.

Don't see a 6-pin, but even if there was one, wouldn't it be dead?
