4.9 Nudge
Description The GPS system in the mojo3D is subject to drift over time. If you use the mojo3D for
extended periods of time, then it may be necessary to adjust the GPS position using
nudge. Nudge uses the wayline as a reference to adjust the GPS position. This can be
thought of as moving all data on the screen (waylines and map data) to the position
of the vehicle.

Nudge can only correct for drift in a single direction which is perpendicular to the
wayline. To accurately correct for drift it may be necessary to nudge on a wayline
heading north/south as well as east/west.
Nudge, step-by-
step To nudge the GPS position, carry out the following steps:
1. Position the vehicle on the tracks of an already driven wayline.

If the GPS position has drifted since this wayline was driven the mojo3D will
display an offset from the wayline on the screen.
2. Tap the light bar at the top of the main navigation screen.
3. Carry out one of the following actions:
• Automatically adjust to the GPS positions to the vehicle by tapping the
message in the centre of the screen.
• Tap or to move the GPS position by a small step.
4. Tap or simply wait for the menu to disappear.
