In addition, GPS can be turned on and off only through the Expert menus. GPS status
also affects which menus may display in the Basic or Expert levels. For example, if
GPS is turned on, then the Speed Camera Alarm menus display. If it is not turned on,
then those menus will not display.
If a menu depends on Level, Mode, GPS , or a different status, that dependency will
be noted in the specific menu entry itself.
The following table lists all the menu options from all levels and modes.
Several menu items only display if GPS is set to ON. These entries are noted in the
following table.
