1. Are the phones installed with exchangable "trannies" to allow easy upgrade to a later phone versions when available?
2. I assume that GSM phones are offered in Europe...Has anyone been able to get a GSM phone installed in the US yet? Is there a special kit for this?
3. Does the "Voice Input System - X5 w/navigation system" (Part no: 84 11 0 137 351) handle ONLY phone functions or does it include some voice control of other functions in the nav system as well?
4. Has anybody managed to install some other kind of phone in the armrest and established a transparent interaction with voice control and navigation system?
