I just installed GPSapp so I've got some to contriute to this. What happens to me with GPSapp is that it starts fine the first time, but strange things occur if I turn the car off and turn it back on again before it has really shut down out of standby. GPSapp is running and will show up when I enter the hijack menu, be the moment I turn the knob, it jumps back to the hijack screen and scrolls through the hijack menu items. GPSapp, though it's display shows up when I go into the hijack menu, is not in the hijack menu.
