SuperGreg,

I appreciate your answers!

the Part Number - would that be on the invoice perhaps ?

As for Sentence 2. I'm not sure either. Let me explain;

S640A is Telephone Pre-Wiring, std. on cars after 04/2002, some pre 04/2002 has a harness thats not BT compatible, hence the (potential) need for a new harness.

The new Retrofit Kit (84 64 0 302 177) should provide handsfree, snap in box etc. Not wiring as this should be present in the car (hence the 03/2002 manufacture date requirement).

For the ULF Box (84 10 6 969 268), this should connect directly to the harness above. So I assume that the AdvancedAutovations harness is a custom replacement for cars not having the harness preinstalled ?

This is very difficult to determine - all i want to know is have anybody mounted the current bt kit on a 2001 x5 - with or without custom harness etc..
