OPERATION

NAVIGATION

The Navigation System uses a Global Positioning System (GPS) antenna mounted under the instrument panel to collect satellite data to compute the position of the vehicle. A navigation unit uses the satellite data to translate the vehicle location to latitude and longitude coordinates. It combines the latitude and longitude with proprietary map data from a DVD unit to perform all system calculations and display formatting. A single DVD disc contains map information for the entire United States. The DVD unit is mounted in the covered underfloor storage compartment at the rear of the vehicle. The map database information works with the application software to perform the following operations:

- Map Guidance
- Vehicle Positioning
- Address Retrieval

The system provides the following additional capabilities:

- Increase or decrease map scale using ENTER and direction arrows
- Scroll through map to a desired destination and press ENTER to begin routing
- Cancel route guidance
- Change language via the EVIC system using the MENU and STEP buttons
- Change display measurement units using the US/M button (Changes units for all displays in the vehicle)

TELECOMMUNICATION

Two buttons on the rearview mirror, identified with ISO icons, control the system: A "phone" button turns the system on and off; a "voice recognition" (or voice command) button prompts the hands-free system to listen for a voice command. The system includes the following features:

- Phonebook - Stores telephone numbers for later recall by name or other verbal identification, called a voice tag, and memory location.
- Four memory locations - Home, Work, Mobile and Pager. A maximum of 32 unique names or voice tags may be stored at the same time, with a different number in each of the four memory locations.
- Voice tag dialing - Dials the number associated with a voice tag and memory location.
- Digit dialing - Dials the telephone number by recognizing the names of the digits as they are spoken.
- Receiving calls - A voice prompt notifies the user of an incoming call. Pressing the "phone" button answers the call.
- Privacy Mode - Switches the call to the handheld telephone and the hands-free system and back again using the "voice recognition" (or "voice command") button and a voice command, if desired.
