Here's my question. Based on looking at the instructions for installing the aux in kit, it looks like the wiring harness on the back of the radio is different than the pre-2003 units. Is it possible to retrofit this newer head unit?

Also, any idea on how much the CD player costs?

Tyrone, are you around? I know you are the master of all e39 retro-fits, maybe you can help?

Thanks in advance, DK.
Gee, thanks! But I can only hold that title while SVTWEB is away ;-) You're in luck because BMW has adapters for putting the new generation (NG) radios in the older cars. Here's what you'll need:

adapter cable, radio 61 12 6 913 957
antenna adapter tubing 61 12 6 913 955
adapter cable, CD changer 61 12 6 913 954 (if applicable)

The new radio units are expensive at around $820 due to a $400 or $500 core. Unfortunately, core is only refundable through Warren T. as far as I know, so you're stuck buying it outright.

Or I suppose you could visit your nearest unfriendly dealer and perform an innocent "switcharoo" while checking out the interior of any remaining E39s. Remember to bring tools!
