Horizon Navmate Navigation/Navteq Map Data - Advent OTOTUN1 Owner's Manual

By comparing the time the signals were transmitted from the satellites and the
time they were recorded, the receiver calculates how far away each satellite is .
The distance of the receiver from three or more satellites reflects its position
on the surface of the planet . Using these distance measurements, the receiver
might also be able to calculate speed, bearing, trip time, distance to destination,
altitude, etc . The GPS position may be displayed as a point on a digital map (at
least three satellites' signals must be received) and as the GPS device moves the
corresponding trace is displayed as well .
Please keep in mind that although the radio signals of navigation satellites will
pass through clouds, glass, plastic, and other lightweight materials, satellite-
navigation receivers will not work underground or in some enclosed spaces .
Horizon NavMate Navigation / Navteq Map Data
The unit is pre-loaded with Horizon NavMate 5 and Navteq map data . The
navigation map data covers the continental US, Alaska, Hawaii, and Canada .
The initial GPS location lock is best established when your vehicle is parked . If
the device is in motion, the signal can take longer to initially connect . Once the
initial coordinates are established, the software will follow you as you move and
navigate .
NOTE: It may take up to 5 minutes to establish the first connection . Subsequent
connections will be faster (30 seconds to 1 minute), but if you have not
used the unit for several days or are very far away from the last location you
used it, it may take up to 5 minutes again to find a strong signal .
