Yesterday I did an out and back flight of two plus hours each way using the new 4.09 software update. The track up feature is outstanding. I only toggled to the map up once to read the name of a town. The features you see ahead on the GPS are the same features you see looking out the window. I only had one problem on the trip. The GPS lost the signal and i had to reboot to get it back. There was a post a while back about the flight timer. There should be a way to keep the time after landing. Right now it resets to 0 when the GPS stops moving. Great Product.
