Couple of places - Peripheral Electronics makes an adapter (BMWPIL) for Alpine and Pioneer - you can get their adapter from http://www.discountcarstereo.com/OEM/CDXSBMW.htm
I bought one as part of an Alpine unit, but I think they sell the adapter seperately. You can also buy the adapter from www.soundgate.com, although the price they quoted me was around $170 MSRP. The code for their part is ABNW35V2.
I got a quote from a local Audio Connection store for the Peripheral Electronics convertor at $99.99.
