In theory, that shouldn't work - each bluetooth device should have it's own unique MAC address (or equivelant).
Another question: I read that when the v710 is using bluetooth in the car it will not ring, it will just show on the display a call is coming in. So that would be great to hear that you heard an audible ring Bryan
Nope didn't hear anything, the display changed on the screen and my wife saw the call coming in . . . Our friend's phone doesn't ring when she gets a call in her Prius the radio mutes and that is the only way she knows a call is coming in if she isn't looking at the screen.
