Interesting: I have two cell phones linked to the G, my iPhone and my company cell that is used less often (Blackjack II). Tried to use the phonebook to make a call on the Blackjack, and the G kept misunderstanding the command (applying it as numbers, saying no number found, or whatever). I tried several numbers, and even tried switching the car off then back on - same thing.

But it's working perfectly with the iPhone, which is the primary phone. Guess the phonebook commands don't transfer? Which seems weird, you'd think that the G just sends a bluetooth command 'Dial these digits' once it hears the name, and it wouldn't care what phone is linked??
