Hi,

short version: I think my car had a MKIV drive, but it's not there now. How do I determine if my wiring is OK to just put in a replacement MKIV drive?

long version: I have a 2005 E53 3.0d I bought used last year, that I suspect it used to have satnav that the drive failed on, so the dealer just yanked the MKIV drive.

I have :
- A loom, part number 6-919-75802, with 2 18 pin connectors on it, one purplish, one light blue. The connectors are dangling where a MKIV drive would've been
- a GPS antenna wire hanging down near the CD stacker (cable P/N 8-377-434 which is a GPS antenna cable according to realoem).
- TV
- Widescreen bordmonitor
- bluetooth

before I go buying a MKIV drive, can someone please confirm the loom 6-919-75802 is the right loom? It doesn't match on realoem so I'm stumped...

Apologies if this is a FAQ.

Cheers + thanks,
Scott.
