It appears that it does not transfer the numbers but rather links into the devices address book. Therefore, it is always synched and if you pair a different phone and come within range you get its address book. It is not transferring from the SIM card (at least that is the way it appears to me.)
does anyone have new information about rSAP and 8700 series. My new car will be a VW as well, and up to now a connection is not possible.
Found no hints on blackberry website.
Any comments apreciated.
