The navigation unit calculates the vehicle position and guides you to the destination. The unit performs map matching
correction, GPS correction, and distance tuning. It also controls the menu functions and the DVD-ROM drive, and
interprets voice commands. With control of all these items, the navigation unit makes the navigation picture signal,
then it transmits the signal to the navigation display and audio driving instructions to the audio unit.
The navigation unit calculates the vehicle position (the driving direction and the current position) by receiving the
directional change signals from the yaw rate sensor and the travel distance signals from the PCMs vehicle speed pulse
(VSP) signal.
The map matching tuning is accomplished by indicating the vehicle position on the roads on the map. The map data
transmitted from the DVD-ROM is checked against the vehicle position data, and the vehicle position is indicated on
the nearest road. Map matching tuning does not occur when the vehicle travels on a road not shown on the map, or
when the vehicle position is far away from a road on the map.
The GPS tuning is accomplished by indicating the vehicle position as the GPS’s vehicle position. The navigation unit
compares its calculated vehicle position data with the GPS vehicle position data. If there is large difference between
the two, the indicated vehicle position is adjusted to the GPS vehicle position.
The distance tuning reduces the difference between the travel distance signal from the VSP and the distance data on
the map. The navigation unit compares its calculated vehicle position data with the GPS vehicle position data. The
navigation unit then decreases the tuning value when the vehicle position is always ahead of the GPS vehicle position,
and it increases the tuning value when the vehicle position is always behind the GPS vehicle position.
The navigation unit can calculate different routes to a selected destination. You have five options:
 Direct Route Calculate a route that is the most direct.
 Easy Route Calculate a route that minimizes the number of turns needed.
 Minimize Freeways Calculate a route that avoids freeway travel. If that is not possible, keep the am ount of
freeway travel to a minimum.
 Minimize Toll Roads Calculate a route that avoids, or minimizes travel on toll roads.
 Maximize Freeways Calculate a route that uses freeways as much as possible.
The navigation unit transmits audio driving instructions before entering an intersection or passing a junction.
The audio instructions come through the audio unit to the front speakers.
NOTE: The front speakers are muted whenever the navigation system is giving guidance commands, and all of the
speakers are muted when the voice control system is being used.
The map data (including all scale rates) is stored in the DVD-ROM. The map data includes:  Road distances, road widths, speed limits, traffic regulations, passing time at junction, distances to junctions, and the driving instructions for audio guidance.
 Latitude and longitude GPS.
