1. Welcome

TeleNav™ 4 utilizes the integration of GPS position determination technology, the Java™ programming
environment, and access to Nextel’s packet data network that are all built-in to the Research in Motion
BlackBerry™ model 7520. TeleNav 4 offers basic services, and one level of enhanced services.

The basic services (TeleNav Tools) include:

• A compass-like indicator presenting your direction of travel, location, and speed.

• The ability to mark the current location as a waypoint that can be labeled.

• A viewer that displays your current location relative to a selected waypoint and to navigate relative to

that selected waypoint.

None of these basic GPS services require you to have Nextel packet data service. They all operate solely within
the mobile phone itself.

The enhanced TeleNav GPS services include all basic services and the additional services noted below:

• GPS navigation that punctually guides you turn-by-turn to any destination address in the Continental

US. If you miss a turn or get off-track, TeleNav will calculate a new route for you. You can enter one or
more destination addresses by calling an automatic voice recognition system, entering them on the
TeleNav website, or keying them directly into the handheld. Optionally, you can input a remote origin
and receive Driving Directions from that origin address to the selected destination address.

• A Business Finder feature that allows you to find businesses or points of interest near your current

location, around a waypoint, around an entered address, or around an airport. You can call the
business first to check availability of an item, or get a reservation, and then navigate to it; or you can
save the address for use later in the day.

• Maps of the area around your current location; a marked waypoint; or an address you enter manually,

or have previously entered. You can pan (adjust left/right or up/down) the map, and zoom in or out.
You can also mark a point under the cursor as a waypoint.

• The ability to personalize the application by selecting the use of US customary or metric distance units,

language for audible guidance, volume and backlight level, timing of displayed graphics, etc.

TeleNav’s servers support these enhanced services via the Nextel packet data network.
