About GPS and satellite signals
The Global Positioning System (GPS) is a worldwide radio navigation system
that includes 24 satellites and their ground stations that monitor the
operation of the satellites. To use GPS, you need a compatible GPS receiver.
Use Bluetooth connectivity to connect to the GPS receiver. To start using a
compatible GPS receiver with Bluetooth connectivity, select Connectivity >
Bluetooth .
A GPS terminal receives low-power radio signals from the satellites and
measures the travel time of the signals. From the travel time, the GPS receiver
can calculate its location to the accuracy of metres.
The coordinates in the GPS are expressed in degrees and decimal degrees
format using the international WGS-84 coordinate system.
The Global Positioning System (GPS) is operated by the government of the
United States, which is solely responsible for its accuracy and maintenance.
The accuracy of location data can be affected by adjustments to GPS satellites
made by the United States government and is subject to change with the
United States Department of Defense civil GPS policy and the Federal
Radionavigation Plan. Accuracy can also be affected by poor satellite
geometry. Availability and quality of GPS signals may be affected by your
location, buildings, natural obstacles, and weather conditions. The GPS
receiver should only be used outdoors to allow reception of GPS signals.
Any GPS should not be used for precise location measurement, and you
should never rely solely on location data from the GPS receiver and cellular
radio networks for positioning or navigation.
To enable or disable different positioning methods, such as Bluetooth GPS,
select Menu > Tools > Settings > General > Positioning >
Positioning methods .
About satellite signals
If your device cannot find the satellite signal, consider the following:
• If you are indoors, go outdoors to receive a better signal.
• If you are outdoors, move to a more open space.
• If the weather conditions are bad, the signal strength may be affected.
• Establishing a GPS connection may take from a couple of seconds to
several minutes.
Satellite status
To check how many satellites your device has found, and whether your
device is receiving satellite signals, select Menu > Tools > GPS data >
Position > Options > Satellite status . If your device has found satellites,
a bar for each satellite is shown in the satellite info view. The longer the bar,
the stronger the satellite signal. When your device has received enough data
from the satellite signal to calculate the coordinates of your location, the bar
turns black.
Initially your device must receive signals from at least four satellites to be
able to calculate the coordinates of your location. When the initial calculation
has been made, it may be possible to continue calculating the coordinates
of your location with three satellites. However, the accuracy is generally
better when more satellites are found.
Positioning settings
Select Menu > Tools > Settings > General > Positioning .
To use a specific positioning method to detect the location of your device,
select Positioning methods .
To select a positioning server, select Positioning server .
Nokia Maps
Select Menu > Tools > Maps .
With Maps, you can see your current location on the map, browse maps for
different cities and countries, search for addresses and different points of
interest, plan routes from one location to another, and save locations as
landmarks and send them to compatible devices.
You can also purchase extra services, such as guides and a turn-by-turn
navigation service with voice guidance.
When you use Maps for the first time, you may need to define an internet
access point for downloading map information for your current location. To
change the access point later, select Options > Settings > Network >
Default access point .
Download maps
When you browse the map on the display, for example, move to another
country, a new map is downloaded automatically. These downloaded maps
are free of charge, but downloading may involve the transmission of large
amounts of data through your service provider's network. For more
information on data transmission charges, contact your service provider.
You can view the amount of transferred data from the data counter (kB)
shown on the display. The counter shows the amount of network traffic
when you browse maps, create routes, or search for locations online.
Almost all digital cartography is inaccurate and incomplete to some extent.
Never rely solely on the cartography provided for use in this device.
To prevent the device from automatically downloading maps through the
internet, for example, when you are outside your home cellular network,
select Options > Settings > Network > Use network > Off .
To receive a note when your device registers to a network outside your home
cellular network, select Options > Settings > Network > Roaming
warning > On . Contact your network service provider for details and
roaming costs.
To adjust the size of the cache that is used for saving maps or voice guidance
files, select Options > Settings > Network > Max. memory card use
(%) . This option is available only when a compatible memory card is inserted.
When the memory is full, the oldest map data is deleted. The cache cannot
be emptied.
Nokia Map Loader
Nokia Map Loader is PC software that you can use to download and install
maps for different countries from the internet to your device or a compatible
memory card. You can also use it to download voice files for turn-by-turn
navigation.
To use Nokia Map Loader, download it from www.nokia.com/maps, and
install it to a compatible PC.
You must use Nokia Maps before using Nokia Map Loader. Nokia Map Loader
uses the Maps history information to check the version of map data to be
downloaded.
1. To download maps or voice guidance files with Nokia Map Loader,
connect your device to the PC with a compatible USB data cable.
2. Open Nokia Map Loader in your PC. Nokia Map Loader checks the version
of map data to be downloaded.
3. Select the maps or voice guidance files you want to install to your device.
Satellite information
The indicator is shown on the display when you browse maps. When
the device tries to establish a GPS connection, the circles are yellow and the
icon is blinking. When the device receives enough data from the satellites to
calculate the coordinates of your current location, the icon stops blinking
and turns green.
To check how many satellites your device found and whether your device is
receiving satellite signals from the satellites, select Options > Map
options > Satellite info .
If your device found satellites, a bar is shown for each satellite in the satellite
information view. The longer the bar, the stronger the satellite signal. When
your device has received enough data from the satellite signal to calculate
the coordinates of your location, the bar turns black.
Initially your device must receive signals from at least four satellites to be
able to calculate the coordinates of your location. When the initial calculation
has been made, it may be possible to continue calculating the coordinates
of your location with three satellites. However, the accuracy is generally
better when more satellites are found.
Browse maps
The map coverage varies by country.
When you open the Maps application, Maps zooms in to the location that
was saved from your last session. If no position was saved from the last
session, the Maps application zooms in to the capital city of the country you
are in based on the information the device receives from the cellular
network. At the same time, the map of the location is downloaded, if it has
not been downloaded during previous sessions.
To establish a GPS connection and zoom in to your current location, select
Options > Find place > GPS position [0] . Your current location is
indicated on the map with .
To move on the map, scroll up, down, left, or right.
To zoom in or out, press * or #.
To switch between the 2-D and 3-D views, select
Options > Map
options > 2D/3D .
To find a location, select Options > Find place .
To use a location on the map, for example, as a starting point for a nearby
search, to plan a route, view its details, or start navigation (extra service),
press the scroll key, and select the desired option.
To define what kinds of points of interest are shown on the map, select
Options > Map options > Categories .
To take a screen shot of your location, select Save > As image . The screen
shot is saved in Gallery.
To save a location as a landmark, press the scroll key and select
Save > As
landmark .
To view saved landmarks, select Options > Find place > Landmarks .
