Navigation modes
Trekker distinguishes three different situations coresponding to three navigation modes: Pedestrian, Free
and Motorized modes.
Pedestrian mode
Walking in areas where streets are available in the map is called Pedestrian mode. This is the default Trekker
navigation mode, providing GPS coverage and mapping functions associated with the installed regional map.
Free mode
Use Free mode to travel in unmapped areas such as parking lots, parks, campuses, or bodies of water.
Motorized mode
Use Motorized mode while traveling by car, bus or train. The main difference between Motorized and
Pedestrian modes is a reduction in the information verbosity level. The speed of motorized travel does not
allow the extent of spoken detail possible in Pedestrian Mode. So verbosity information is shorter to reduce
the length of the spoken message.
Points of Interest (POI)
POIs are landmarks that you may encounter in your travels. The system handles three different types of
Points of Interest:
Navteq POIs: commercially available information such as restaurants, hospitals, schools, train stations
included in the Navteq Maps. This information is included in the Navteq Maps.
Personal POIs: landmarks created by the user by means of the recording POI feature. Personal POIs can
be transferred to the main computer for backup purposes or shared with other users. Personal POIs are
organized in CSV (Comma-Separated Values) format.
External POIs: Trekker can handle POI information coming from third party sources. The system supports
any database in CSV format, provided they contain at least the GPS coordinates (longitude, latitude) and a
name, with a specific organization. Any database different from the Navteq or your Personal database is
considered as external and should be managed using the Map Manager tool in the External database page.
