Mk-3 Navigation Computer
The Mk-3 navigation computer is located in
the left side of the vehicles trunk or cargo area.
(In the case of the Z8 it is installed in the stor-
age box behind the passenger seat.)
The navigation computer housing contains:
 Map CD drive
 Hardware for navigation function
 GPS receiver
 Gyro sensor
 Output for audio interface
 Output for visual display
 Cooling fan for unit
There are two different hardware versions available dependent on the angle of installation
in the vehicle (horizontal or vertical). The Mk-3 is compatible with both board monitor or
MIR display units.
(See workshop hints for configuration instructions)
Identification of the Mk-3 computer over the previous versions is easy due to a change in
the face plate design and the elimination of the “CD-IN” LED.
