Automatic day/night colours:
Based on the time and position given by the GPS
device, iGO is able to calculate when the sun rises and sets at your current location
on this particular day. Using that information iGO can change between the day and
the night colour schemes a few minutes before sunrise and a few minutes after
sunset (Page
). 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.

Baud rate:
The speed of the communication between the GPS receiver and the
PDA can be set in Bauds, representing the number of signal events per second.
Usual values for GPS devices are 4800, 9600, 19200, 38400 and 57600. See also
Page .
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.
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 iGO this value is shown as
‘Estimated Arrival’ on the Route Information screen (Page ).
40
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 iGO this value is shown as
‘Time left’ on the Route Information screen (Page
).

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.
Lock-on-Road:
This function of iGO will always keep the blue (yellow at night) 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 be shown over a different street
on the map. You can only avoid that by using good quality GPS equipment
positioned so that it has a direct view to as large a portion of the sky as possible.
Normally Lock-on-Road is always active in iGO when GPS position is available. See
