So I pull into a gas station yesterday, turn off the car, get out, swipe my CC , start the pump, grab my cell phone and dial my voicemail to get a message. I put the phone to my ear and I can't hear anything. As I open the rear door to get something from my briefcase, I hear my voicemail talking to me through the car speakers. I am confused. What's the deal? I look over to the nav screen and it is blank. The green light for BT call in progress is lit above the nav screen. But the keys are in my pocket and the car is off. So I listened to the message while leaning inside the car from the back seat. How odd. I guess the BT connection from the phone didn't disconnect, but there shouldn't have been power in my 2004 X. Or should there?

Any gurus know the answer?
