I just got a call from the dealer who said they had to reconfigure or reset the teleaid system in my 320 CDI and it is now working. Does anyone know of this problem in MY 05? I think the tele-aid system is a newer (digital)version. He also mentioned that the installed phone equipment (minus cradle and phone) is for the new Moto V710 (Verizon). Does anyone have any further info on the phones and when the dealers will get them? I've been waiting a few months already and still don't have the cradle or phone to date. Everyone you ask seems to have a different answer. If I could get some reliable source to tell me here, I'd feel a bit better.

This thread may give you some useful info.
