For those that were following my thread on the weird issue I was having after upgrading to v27 on the nav, this was resolved with a trip to the dealer, and a new Bluetooth/Assist TCU module. Apparently they have yet another new module... I was previously aware of the following:

03/2005 - 05/2005 84-10-6-964-114
06/2005 - 08/2005 84-10-6-965-056
09/2005 - ???????? 84-10-6-963-798

I had the -114 in my 5/2005 production X5, but they replaced it with 84-10-6-978-529, which I guess is brand new. Seems to work like a charm overall - except that my v710 phonebook doesn't seem to be loading... after re-paired the phone with the system, the nav screen said "Updating Phonebook", and just hung there for several minutes. Not sure what the problem is, as this always worked fine with the old BT module.
Any thoughts?
