ok...here is the update

The Audiovox 6600 (Verizon) paired ok with my '05 E53

GOOD
Incoming calls ring through both the phone and stereo
Incoming calls can be picked up on the MID or SteeringWheel
Outgoing calls can be dialed on the phone
Outgoing calls can be dialed on the MID

BAD

No transfer of address book

Sometimes they work together right away as soon as I get in
Sometimes it says "Activate Phone" for a while
Sometimes it takes a few seconds /few minutes to Activate
Sometimes it activates in the middle of a call, so I'll be in mid sentence talking with the phone to my ear, and then voices "appear" from the stereo
I'm not really sure if/how to get them to activate faster

when dialing on the MID, if I have to do a *82 to unblock, sometimes I do the *, then the ^ to get back to the numbers, then press 8 and it overwrites the * ....but sometimes it doesn't <shrug>

all in all, I'd say I am generally happy, and maybe someday they will update the software to allow addressbook transfer.
