I wonder if anyone else has experienced this strange behaviour while navgating. When I touch the screen while navigation map is displayed, the navigation map switches into the zoom/pan map mode. Then I press back button and the map switches back to navigation mode. But after couple of seconds, it skips back to zoom/pan mode, where the map does not shift automaticaly with my position change. I press back again, but few seconds later the zoom mode is back. It is annoying. Whenever I want to see my location in navigation, I need to press the back button to show navigation for a few seconds and in a while it is back to zoom mode. Is this some bug in software?
