Vehicle Position - Jensen VX7020 Operating Instructions Manual

VX7020
iGO primo software provides turn-by-turn visual and voice assistance to direct you
to your selected destination. The software quickly calculates step-by-step
directions to any destination available on the included navigation map.
The iGO primo software uses Global Positioning System (GPS) satellites, and a
digital roadway map database to calculate and display travel directions. The sys-
tem's GPS antenna receives signals from a constellation of 24 satellites orbiting the
earth and uses the strongest signals to determine your position to within meters.

Vehicle Position

The iGO primo software's computer considers vehicle speed and heading changes,
together with longitude and latitude information, to accurately determine vehicle
heading and position on a digital map.
Signals from GPS satellites are used to determine the vehicle location. Three
(good) or four (best) satellites must be received to accurately determine location.
The GPS reception status is indicated by the GPS symbol on the map.
Map and Information Database
The map database used by your iGO primo software was created using
high-resolution aerial and land based data collection.
Car navigation maps are frequently updated. While the database was judged to
be as accurate as possible at the time of its release, a map database can never be
100% accurate. Road information that is maintained in the map databases, such as
turn restrictions or road names may change over time.
iGO primo mapping is supported by the mapping manufacturer. iGO offers
periodic updates for data such as roads, new addresses, and other navigational
information that will keep your navigation system up to date and provide the best
possible experience. For updates and add-on options, please visit their website at
www.naviextras.com. A free program called "toolbox" can be downloaded from
this site so you can create a copy of your map as a backup, as well as assist in easily
checking for updates and optional features that are available. We
recommend that you back up your map because If your map becomes damaged
or erased, or if the card is lost without being backed up, you will need to purchase
a new map package.
To report incorrect information, missing addresses, or other map data, click on
"REPORT A MAP ERROR" under the SUPPORT section of www.naviextras.com.
Errors will be verified and corrected in a future map update.
We recommend that you check your map with this system now and every six
months to insure you always have the most up-to-date operating system
and maps.
