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 / Tele Atlas Map Data
The VM9424BT is pre-loaded with Horizon NavMate 5 and Tele Atlas map
data. The map data covers the continental US.
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.
