Nav and new cars, I was in the market early this year. Many new cars will not have navigation, and the trend is using a cell phone that connects to the car's systems. Over the past year or so seen many posts that people are using cell phones for navigation, as they are more updated and have other features that built-in Navigation does not have. We ended up buying a car without factory navigation. After several months have now adjusted to the cell phone way. I use Waze, which has warnings of cars parked on the side of the road, stuff in the traffic lanes, and police in the area. I just completed a 1,600-mile trip and am now convinced cell phone is better.
