My issue. I am walking to my car, talking on the phone. When I turn the car on, I want to transfer from the phone to the bluetooth in the car/nav. unit. If I'm in my car, I can call/receive phone calls fine, but I can't figure out how to transfer a call to my car bluetooth, when I get in and I'm ready to drive off. Instead, I have to tell the person, I'll call them right back, as I have to make the call from the bluetooth setup. How is this possible? Thanks.
