How Do I Use It?
Type 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 TRAX325 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 view to let you see the surrounding
area. You have the following controls for Automatic
Overview:
• Turn Distance for Overview: The map view will be
switched to Overview mode if the next route even is at
least as far as this value.
• Default Zoom Level: Overview mode will appear with
this zoom level. You can scale the map in Overview
mode but next time Overview appears again, this
zoom level will be applied.
