the top box. Settings can be toggled by using the joystick and the options available are as follows.
(The default settings are listed first.)

Screen 35B: GPS Source Change Warning Screen
If you press ABORT the GPS source remains unchanged. If you press YES, you can use the joystick to
toggle the GPS SOURCE between INTERNAL and EXTERNAL. When set to INTERNAL, the internal
GPS receiver will be used, and key 3 will be displayed, to allow access to the GPS Status screen. When
set to EXTERNAL, the Skymap IIIC will enter Tracker Mode and use data generated by an external GPS
receiver in the same way as a Tracker IIIC does. If you have a Tracker IIIC and select INTERNAL, an
error message will be displayed because an internal GPS receiver will not be found.
