I know I should RTFM, but I don't and I learned something new that I have not seen mentioned here. <p>While stuck in traffic, I used the nav system to look up a pizza joint near my home. When I found it in the nav system, i clicked on the "information" button to get the phone number. The address and phone number displayed, along with two buttons, "map" and "call". Clicking on call (using the nav controller) caused the bluetooth system to call the pizza joint. Very nice integration!<p>I had no idea the nav system was linked to the bluetooth phone system. Guess I'll have to RTFM and find out what else I don't know.
