MARK II NAVIGATION SYSTEM
The Mark II Navigation system became available as factory installed optional equipment for
all E38/E39 vehicles starting with 9/97 production. Manufactured by Phillips, the Mark II
system is the second generation Navigation system based on the Mark I system introduced
in October 1996.
To the operator, the Mark II system changes are almost transparent. The overall system
function and most of the systems components carry over from the Mark I system.
The Mark II system provides:
Reduction in the total number of components,
Simplified control module interface,
Automatic calibration procedure.
COMPONENT LOCATIONS AND CHANGES
Trunk area:
At first glance, the reduction of Board Monitor/Navigation system components
in the left side trunk area, is immediately recognized.
Though the Navigation Computer looks the same as the Mk-1 from its installed posi-
tion, it is actually a different component. It provides expanded capabilities and simpli-
fied system interface compared with the same component of the Mark I system.
The GPS receiver module is
also a different component. It
has an ELO connector for 26
pin breakout box compatibility.
The radio and audio system
amplifier are the same compo-
nents of the previous system.
The Video Module of the Mark I
system is not utilized with the
Mark II system in the US market.
All of the Navigation system/Board monitor functions previously handled by the
video module are controlled by the Mk-2 navigation computer.
