This one has shell output again, when you try to load routes.
Okay, I put that file in place, started it from the shell, then exited back into the player app so I could select GPSapp from the Hijack menu:
empeg:/empeg/bin# /drive0/var/gpsapp/gpsapp
empeg:/empeg/bin# GPS app started
exit
logout
Shell exit

hijack: removed menu entry: "GPSapp"
And I selected "Load Route" from the player's front panel, and it said "no routes found", and I got NOTHING on the serial port. Nothing at all. Only what you see above.
