How Do I Use It?
Map
TRAX350 works with digital maps which are not simply the computerised
versions of traditional paper maps. Similarly to the paper road maps, the
2D mode of digital maps show you streets, roads, and elevation is also
shown by colours. In 3D mode, you can see the altitude differences, for
example valleys, mountains and elevated roads.
You can use digital maps interactively: you can zoom in and out (increase
or decrease the scale), you can tilt them up and down, and turn them
left and right. In GPS-supported navigation, digital maps facilitate route
planning.
North-up map orientation
In North-up mode the map is rotated so its top always faces North. This
is the orientation in 2D map view mode and in Overview mode. See also:
Track-up map orientation.
Overview mode
You can instruct TRAX350 to automatically switch to Overview mode if the
next route event is in a distance. In Overview mode the map is shown in
2D but scaled down to a predefined zoom level. When you approach the
next route event, the previous 2D or 3D map view returns automatically.
Route
A series of destinations to be reached one after the other. A simple route
contains one start point and only one destination. Multi-point routes
contain one or more via points (intermediate destinations). The last route
point is the final destination and the route is cut into different legs (from
one destination to the next).
Scheme
TRAX350 comes with different colour schemes for the map for daytime or
night use. Schemes are custom graphic settings for the map and they can
have different colours for streets, blocks or surface waters in 2D and 3D
modes, and they display shades or shadows in different ways in 3D mode.
One daytime scheme and one night scheme is always selected. TRAX350
uses them when it switches from day to night and back.
Track-up map orientation
In Track-up mode the map is rotated so its top always points in the currend
driving direction. This is the default orientation in 3D map view mode. See
also: North-up map orientation.
