Selling my CP600BMW that I've used in my E39 M5 & Z4M:

Sells for about $236 new from Europe. Will sell mine for $150 + $10 2-day Priority Mail shipping = $160 total.
Connects to standard BMW CD changer cables (not included), and looks like a stock changer to your head unit. Plays MP3 files, but does not support AAC (iTunes MP4). See above link for more details. Super-fast and a great way to put a ton of music in your car without using the old clunky CD changer option.
IM me for my PayPal address and I'll ship within 24 hours.
