Usb Tape Deck Bmw Audio Problem?

Bmw audio problem? - usb tape deck

I have 1994 BMW 318is. than in Europe. I have a Pioneer 6 Disc changer in the trunk and a Pioneer tape deck no longer works. I bought a new package of Pioneer 2900th The new game has a USP IP port on the back for connecting 6-disc changer. My problem is the cable that goes from 6-disc has a bwmpio port. bmwpio a cycle of 13 pins, but Squair USB IP is an axis is 12 I really need to know to connect the two connectors together to share a guide pin would be useful, we hope that someone else has this problem, and I can keep my changer too.
