GPS accuracy
Several factors have impact on the deviation between your real position and the one
given by the GPS device. For example, signal delay in the ionosphere or reflecting
objects near the GPS device have a different and varying impact on how accurately the
GPS device can calculate your position.
Map
Audiovox NAV 104 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 and mountains,
elevated roads
, and in selected cities
3D landmarks
and
3D buildings
are also
displayed.
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 rotate 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
for example in
Find on Map
.
Road Safety Camera
Special alert points for speed, red light or bus lane cameras. Different data sources are
available. You can configure Audiovox NAV 104 to warn you when you approach one of
these cameras.
Detecting the location of
Road Safety Cameras
is prohibited in certain countries. It is
the sole responsibility of the driver to check whether this feature can be used during the
trip.
The software is capable of showing and warning for more than just cameras. Various
other types of proximity alert points like school zones and railway crossings are also
available.
