Good info here I was curious about using the sync with my app on the phone.....I do not like how it would make you stop and enter a destination.
When I was looking at trucks a nav system was kinda on my list.....when I found my truck on the lot it had everything I wanted its a lariat with everything except the touch screen. the more I thought about it the more I talked myself out of having the touch screen nav. I have used my I-phone more than once for directions.......I had to work in N.Y during the hurricane last year and I used my phone. Honestly the turn buy turn on my phone was just as good or better than any nav system I have seen in a vehicle.
Last weekend I was going to try and sync my phone app to the truck but if you have to stop to enter an address I dont think I will bother.
