I have the stock navigation with Bluetooth and I understand these are separate units. However, today I received a call and on my navigation screen it said "Bluetooth" and then changed to the phone number of who was calling. That was the first time I saw it and it doesn't do it anymore. Anyone have any ideas as to how this works? Does it have to be switched on or something? Now when I get calls, it will still ring through the truck, but doesn't display on the screen.

 

i didnt think you could get stock nav with bluetooth. Do you have a dealer installed add on?

 

No, it is all stock. It is a 2010, maybe this was a change they made????
