6.2.2 GPS
• Click “GPS”.
This brings you to the screen that tells you the GPS reception status; on this screen:
The green “
V ” means that GPS is activated.
“NO Fix / FIX: 2D/FIX: 3D” indicates better signal reception, and therefore more accurate positioning.
“SAT”: indicates the number of satellites used to calculate your position.
The vertical bars show the satellites detected:
•
grey the device is receiving satellite signals but cannot use them to establish your position.
• green the device is using the satellite signals to calculate your position.
• The numbers under the vertical bars give the number of the American satellite.
Coordinates:
longitude and latitude calculated by the system.
Direction arrow: shows the direction of travel between 2 position calculations by the GPS.
• Click on “Back” to return to the previous screen.
Comment:
The ViaMichelin Navigation X-970 is fitted with an SiRF Star III type GPS, the latest generation of GPS, which
works even in poor reception conditions.
After selecting a destination and before the navigation instructions show your route, the GPS must have three
pieces of information to calculate the route: the position, direction of travel and speed. You may consult the GPS
screen on your mobile device to follow the GPS signal acquisition.
The time the GPS takes to acquire this information varies depending on how much time has elapsed since the
device was last used:
• your ViaMichelin Navigation X-970 has not been switched on for more than 24 hours (“cold start”): in this
case the time needed to acquire satellite signals may be quite long (10-15 minutes), and the message “Satellite
detection. This may take several minutes” is displayed on the navigation screen.
• your ViaMichelin Navigation X-970 has not been switched on for more than 4 hours (“warm start”): GPS reception
may take several minutes (5 minutes) and the message “Satellite signal acquisition in progress” is displayed on
the navigation screen.
• you switch on your ViaMichelin Navigation X-970 after switching it off a few minutes ago (“hot start”): satellite
reception is almost immediate and navigation can continue.
GPS acquisition time also varies depending on the surroundings:
• athermic windscreens:
if your vehicle is equipped with an athermic windscreen, GPS reception may be
slower.
• car park/tunnel/building: satellite signals do not travel through walls, so you will not receive a GPS signal if your
device is in a building, car park, tunnel, etc.
• urban “canyoning”: reception will be slower in urban areas if buildings are high, streets narrow or there
are a lot of trees. Go to an open space to improve reception.
• weather conditions: in poor weather (heavy snow, etc.), GPS reception may take slightly longer.
When using ViaMichelin Navigation X-970 for the first time, we advise you to do so in an open space in order to
ensure the best possible satellite reception. Activating the GPS system for the first time can take several minutes,
depending on the surroundings and the quality of the GPS signals.
