After the MOB keypress, the CHART screen INFO BAR
automatically appears, even if you haven't pressed the INFO
key. This INFO BAR shows the *MOBXX* waypoint as your
active waypoint. If you press the WAYPTS/ROUTES key, you'll
see the *MOBXX* waypoint in the list, and *MOBXX* waypoints
are also displayed on the 3-D STEER, STEER, and TRIP
screens.
If you press the MOB key a second time—before you arrive at
this first *MOBXX* waypoint—you'll have to press the YES, GO
NOW key to confirm, because a second MOB keypress would
save your latest position and make this your active waypoint
instead.
If you've stopped navigation, it is automatically resumed as
soon as you press the MOB key.
