Interruption of Other Services 
Whenever the TeleNav GPS Navigator application needs to contact its servers (such as when generating a route), 
it uses your carrier’s data service. When the TeleNav GPS Navigator application uses your carrier’s data service, 
other services such as SMS messaging and conventional cellular calls are not available. Typically, this interruption 
of other services lasts no more than 20 seconds. 
When incoming calls are blocked due to TeleNav GPS Navigator’s use of your carrier’s data network, phone calls 
go to your voice mail if you have a voice mail service available. 
Switching Between Applications 
Press the ALT key and the ESCape button concurrently to launch the BlackBerry application switcher. This will 
allow you to leave TeleNav running in suspended mode while looking at your e-mail, or using another application. 
When you use the switcher to return to TeleNav, it will move to the foreground and resume operation. If while 
another application was in the foreground you have left the navigation route, TeleNav will sound a deviation jingle 
and obtain a new route for you.
