05 X5 with Sony Ericsson z600 and s700
 

Does anyone know whether Sony Ericsson z600 and s700 work with 05 X5 Bluetooth? The production date is 01/05.
When I use z600, I can accept and make calls, but it locks up the phone. Also bluetooth gets stuck at loading phonebook.

The ones supported by BMW is old and not the latest and greatest.
I will be getting s700, will it work with BMW bluetooth?

I haven't heard any direct feedback on either phone yet, although in the past the SE phones have been pretty good with compatability to the BMW Bluetooth systems.
