I'm moving a BMW CB from an '07 LT to an '08 LT. Both are equipped with VOICE II. Can anyone tell me where the PTT button connects to the VOICE II? I thought I had identified all of the connectors before I had to button the '07 back up, but I apparently missed one. I really don't want to open it back up to figure out what I missed. There is only one matching 2 pin connector coming out of the VOICE II on the '08, and it is connected to the GPS. Any ideas?
