Button Description
Keep Position on Road
This feature allows car drivers to always correct GPS position
errors by matching the vehicle position to the road network. For
pedestrian navigation, this feature is automatically disabled to let
the software show your exact position.
By turning off this feature you also turn off the GPS position
error filtering. The position shown on the map will be subject to
all position errors and position fluctuations.
Off-route Recalculation
This switch tells Nav N Go iGO 8 whether to automatically
recalculate the route when you deviate from it. If this feature is
turned off, you need to initiate route recalculation manually
otherwise navigation will be stopped until you return to the
originally recommended route.
Setting another point than the current GPS position as the start
point of the active route will automatically disable this feature.
Restore Lock-to-Position
If you have moved or rotated the map during navigation, this
feature moves the map back to your current GPS position and
re-enables automatic map rotation after the given period of
inactivity.
Automatic Overview
This feature switches the map view to Overview mode when the
next route event is at a distance. Overview is a zoomed out 2D

controls for Automatic Overview:
• Turn Distance for Overview: The map view will be
switched to Overview mode if the next route even is at
