¾ Automatic route recalculation: If this function is enabled (6.1.8.1), Mio Map
recalculates your route if you deviate from it. When you miss a turn or avoid a
roadblock, Mio Map waits for a few seconds to be sure you do not follow the
route any more, then recalculates the route based upon your new position and
heading.
¾ Automatic day/night colours: Based on the time and position given by the
GPS device, Mio Map is able to calculate when the sun rises and sets at your
current location on this particular day. Using that information Mio Map can
change between the day and the night colour schemes a few minutes before
sunrise and a few minutes after sunset (6.1.2). As additional information to
help your orientation, the sun is shown in the sky when you display the map in
3D mode with a low viewing angle, and the sun is near the horizon.
¾ Elevation: When the GPS receiver can see at least four GPS satellites, it can
determine its current position in three dimensions. In this case the elevation is
calculated together with the latitude/longitude position. Note that some older
GPS units may provide incorrect elevation data because they use a simple
ellipsoidal earth model rather than a database that contains local sea levels.
You should also be aware that the elevation value is generally less accurate
(by at least a factor of 2) than the horizontal position. See also 2D/3D GPS
Reception.
¾ ETA (Estimated Time of Arrival): A frequently used expression in navigation.
It represents the time when you will reach your destination based upon
calculations using the remaining part of the route and available information of
the roads used. This estimation can only be used as a general reference. It
will not be able to take into account your future speed or the traffic delays. In
Mio Map this value is shown as ‘Estimated Arrival’ on the Route Information
screen (4.5.1.5).
¾ ETE (Estimated Time Enroute): Another frequently used expression in
navigation. It represents the time needed to reach your destination based
upon calculations using the remaining part of the route and available
information of the roads used. This estimation can be used only as a general
reference. It will not be able to take into account your future speed or the
traffic delays. In Mio Map this value is shown as ‘Time left’ on the Route
Information screen (4.5.1.4).
¾ GPS: Abbreviation of Global Positioning System. This system is operated by
the DoD (the Department of Defense of the Unites States Government). It
consists of 24 satellites orbiting Earth, and several ground stations to keep the
satellites in sync. To calculate your position, your GPS device uses the signals
received from those GPS satellites that are currently visible at your location.
You can use this service free of charge.
¾ Lock-on-Road: This function of Mio Map will always keep the green arrow
representing your actual position on the nearest road. This automatic feature
is necessary as the position given by the GPS receiver is not perfectly
accurate. Under normal circumstances Lock-on-Road will eliminate the
occasional position error. If the corridor of error is too large, your position may
