With the BNS 5.0 navigation system, it is possible to
navigate and listen to CDs simultaneously. For this
purpose, the system is equipped with an internal
memory into which the required map data can be
loaded after entering the navigation destination.

After entering the route, the system first computes
the distance to the route destination.

The map features of the route are then copied to
a memory integrated in the system. If the CD is
removed during the copy process, the system
displays the following query

"Do you want to cancel loading the route features?"

to indicate that the corridor has not been loaded
completely.

After completing the copy process, the navigation
CD can easily be removed.
The map data copied to the internal memory is also
available for navigating to other route destinations
within the copied area. This means that it is not
necessary to load the navigation CD to navigate to
each new navigation destination.

Behaviour of the internal map memory while driving

382_053

After entering the route destination a map section is
copied to an internal memory. The map section
consists of a location radius, a destination radius as
well as a slightly narrower route corridor in
between.

When the vehicle is driving towards the destination,
the location of the vehicle changes. To make
optimum use of internal memory, the position and
size of the location radius are updated continuously
by the system when the navigation CD is loaded.
Likewis, the size of the destination radius as well as
the width of the corridor are updated continuously
in the internal memory. In codedthe event that the
navigation CD is removed, this ensures that the
optimum map section is always stored in the
system memory.

When the navigation CD is removed from the
system, the map content stored at the time of
removal of the CD remains stored in the system
memory. The map content remains stored in the
deactivated system for 72 hours.
This enables one to enter a route from town A to
town B and to navigate between town A to town B
over a lengthy period of time without having to
reload the navigation CD.

If the actual location and the destination are too far
apart when the navigation CD is removed, the
system may request that the navigation CD be
reloaded while navigating to the destination.

The size of the corridor is defined by the size of the
system memory. Due to the different density of the
navigation data in towns and in sparsely populated
areas, it is not possible to specify the size of the
corridor area.

Note

When map data is stored in the system, the static current consumption of the system rises
slightly. Map data can only be cleared prematurely by disconnecting the system from the power
supply. Please bear this fact in mind when performing static current measurements on the
vehicle.

Standard sound system

This sound system has an auxiliary 5-channel DSP amplifier, the digital sound package control unit J525 which
is diagnosable via CAN. The amplifier supplies the front two-way systems, the rear two-way systems and the
central loudspeakers integrated in the dash panel.
The standard sound system is standard equipment of the concert and symphony radios as well as the
navigation systems with MMI operating logic. These radios or navigation systems do not use an internal
amplifier.

All loudspeakers are diagnosed via the amplifier, i.e. via address word 47. Vehicle model, equipment,
networking and type of driving noise compensation are also coded in the amplifier.
