I received my new work phone yesterday, a Droid X, as an upgrade from my older BlackBerry. The BlackBerry's bluetooth sync worked flawlessly and the phonebook downloaded with no issues. With the Droid I've gotten it to sync on the Acura and the BMW with no issues except on the car I drive all the time (my 2007 G35X

) it will sync BUT when I go to make a call the sound goes up and down and I can hear the person talking but they can't hear me. I've tried un-pairing and re-paring it a couple of times and it's always the same.
I've seen a couple people that seem to have the same issue and others telling them their doing it wrong

. So I was wondering if anyone on this board has been able to sync a Droid X and have it work properly.
Thanks!
