Speed Signals
A speed signal is provided to the navigation computer for detection of distance traveled and
vehicle speed to calculate the vehicles position on the digital map. The input is a processed
signal provided by the vehicles DSC control unit.

Mk-3 navigation
The GPS antenna passes the signal to the GPS receiver incorporated in the navigation
computer. A CD with map data is loaded in the CD drive of the navigation computer. The
navigation computer combines the vehicle position calculated by the GPS with this map
data.
The current position of the vehicle can be shown on the on-board monitor by selecting
“Emergency” from the main menu.
The driver can enter a destination. The navigation computer calculates a route from the
current location to this destination based on selectable criteria (main use of highways,
shortest distance, etc.). The calculated route is shown in the route display.
The navigation computer generates the RGB color video signal for all on-board monitor
displays. These three signals are sent over separate shielded wires to the on-board mon-
itor.
In the case of the E52 MIR (also referred as radio navigation) which does not have a color
display, the visual display data is sent via one wire called the navigation bus. On both sys-
tems, color and monochrome display, the audio output from the navigation computer for
voice directions is sent over two separate wires.
The driver has the choice of displays that utilize a color map with an icon of the vehicle
being traced on the map or the use of arrow indicators and distance data shown on the
on-board monitor display. Vehicles equipped with the wide screen board monitor have a
split screen option that includes both display methods. The MIR only makes use of the
arrows and distance display. With the assistance of voice prompts, the navigation
computer indicates how and where to get into the correct lane or turn off.
The navigation computer calculates the distance traveled from the wheel speed signal
delivered by the DSC control unit.
The gyro incorporated into the navigation computer housing informs the navigation com-
puter when the vehicle is turning. An alternative route is re-calculated automatically if the
driver does not follow the original route instructions.
Once the driver has reached their destination, the navigation computer is ready for
another destination input.
Refer to the on-board monitor owners manual for instructions on using the navigation system
software.
