About A-GPS support
Depending on your service provider, your BlackBerry® 
device might be enabled with Assisted Global 
Positioning System (A-GPS) support.
If your device is enabled with A-GPS support, when 
you make an emergency call from your device, an 
emergency operator should be able to estimate your 
approximate location (subject to A-GPS limitations). 
Warning:
In an emergency, always provide detailed information 
about your location to the emergency operator. 
Because of certain limitations in A-GPS technology 
and emergency infrastructure, the emergency operator 
might not be able to estimate your location using only 
A-GPS information.
Acquire the GPS position of your 
device
Your BlackBerry® Global Positioning System (GPS) 
location is determined using information from GPS 
satellites, and it is expressed as a longitude and 
latitude. To acquire your BlackBerry satellite position, 
in the device options, click Location Based Services. 
Click the trackwheel. Click Refresh GPS.
Note:
If you cannot acquire your BlackBerry satellite position 
by clicking Refresh GPS, try again when your 
BlackBerry device is exposed to a wide area of open 
sky.
About location-based services
The privacy setting for location-based services controls 
whether programs on your BlackBerry® device can use 
the GPS position of your device. For example, a 
program could use the GPS position of your device to 
give you driving directions.
Change the privacy setting for 
location-based services
To set the privacy level for location-based services on 
your BlackBerry® device, in the device options, click 
Location Based Services. Perform one of the 
following actions:
• To be prompted each time a location-based 
service program wants to use the GPS position of 
your device, set the Privacy Setting field to By 
Permission. Click the trackwheel. Click Save.
• To prevent location-based service programs from 
using the GPS position of your device, set the 
Privacy Setting field to Restricted. Click the 
trackwheel. Click Save.
• To allow location-based service programs to use 
the GPS position of your device, set the Privacy 
Setting field to Unrestricted. Click the trackwheel. 
Click Save.
