Automatic route recalculation:
When this function has been enabled, the navigation program will recalculate the route if you
deviate from the planned route. If you miss an exit or need to go around a closed road, the
program will wait for a few seconds and determine whether you are really no following your
planned route (this time can be defined in Advanced Settings), and recalculates the route based
on your current position and driving direction.
Driving direction:
A type of map orientation where the map is always aligned to the direction of travel. See also =>
North orientation and => Map orientation.
Elevation:
When receiving signals from four or more satellites the GPS receiver can calculate the position
in three dimensions. In this case, the elevation is calculated along with latitude and longitude.
Please note that elevation data is usually less accurate (at least twice) as the geographic
coordinates. See also 2D/3D GPS tracking.
ETA (Estimated Time of Arrival):
A commonly used term for navigation. It represents the local time at which you will arrive at your
destination. It is calculated based on the remaining distance and different information on the
roads to be used. This information is a reference value only. It does not take into consideration
your future driving speed nor any possible traffic jams, etc. Your navigation device will show this
value as "Estimated Arrival" on the Route Information display.
ETE (Estimated Time Enroute):
A commonly used term for navigation. It represents the time you will take to arrive at your
destination. It is calculated based on the remaining distance and different information on the
roads to be used. This information is a reference value only. It does not take into consideration
your future driving speed nor any possible traffic jams, etc. Your navigation device will show this
value as "Time Left" on the Route Information display.
GPS:
Acronym of Global Positioning System. This system is operated by the Department of Defense
of the United States of America. It consists of 24 satellites orbiting the Earth as well as several
ground stations controlling satellite synchronisation. The receiver calculates the satellite position
based on the almanac data contained in the signals they broadcast, as long as they can be
received at your present position. This service is free.
Keep Position On Road:
This function will always place the blue arrow (yellow at night) that indicates your current
position onto the next available road. This setting is necessary because the GPS position
calculated by the receiver is not 100% accurate. Under normal circumstances the Keep Position
on Road function will eliminate rarely-occurring positioning errors. However, whenever the error
rate becomes too high, it is likely for your position to appear on a different road on the map. The
Keep Position on Road function is enabled by default as soon as a GPS position can be
