Surround sound
General notes
If your vehicle is equipped with the harman/
kardon® Logic 7® surround sound system,
you can set the optimum surround sound for
every passenger.
The harman/kardon® Logic 7® surround
sound system is available for the following
operating modes:
Rradio (FM only)
Rsatellite radio
Raudio CD
Raudio DVD (MLP, dts, PCM and Dolby
Digital audio formats)
RMP3 (including SD memory card)
RBluetooth® audio mode
RMedia Interface
Rvideo DVD (PCM, dts and Dolby Digital
audio formats)
RAUX
Because many DVDs contain both stereo and
multi-channel audio formats, it may be
necessary to set the audio format
(Y page 223).
iThe Logic7® On function enables
playback of, e.g. stereo recordings with a
surround sound experience for every
passenger. It enables optimum playback of
music and films on CD, audio DVD or video
DVD with multichannel audio formats, such
as MLP, dts or Dolby Digital. The resulting
audio experience reflects that intended by
the sound engineer during the original
recording.
iIf you select  LOGIC7® Off, the sound
system plays the tracks as stored on the
medium. Due to the design of the
passenger compartment, an optimum
audio experience cannot be guaranteed for
all passengers.

128 kbit/s.
Surround-sound playback does not
function for mono signal sources, such as
AM radio mode.
If radio reception is poor, e.g. in a tunnel,
you should switch off Logic 7®, as it may
otherwise switch between stereo and
mono and cause temporary sound
distortions.
On some stereo recordings, the sound
characteristics may differ from
conventional stereo playback.

COMAND calculates the route to the
destination without taking account of the
following:
R Traffic lights
R Stop and right-of-way-signs
R Lane merging
R Parking or stopping prohibited areas
R Other road and traffic rules and regulations
R Narrow bridgesGWarning
COMAND may give incorrect navigation
commands if the data in the digital map does
not correspond with the actual road/traffic
situation. Digital maps do not cover all areas
nor all routes within an area. For example, if
the traffic routing has been changed or the
direction of a one-way road has been
reversed.
For this reason, you must always observe
applicable road and traffic rules and
regulations during your journey. Road and
traffic rules and regulations always have
priority over the navigation commands
generated by the system.
GWarning
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Looking at the icons or map display can
distract you from traffic conditions and
driving, and increase the risk of an accident.
General information
Operational readiness of the navigation
system
The navigation system must determine the
position of the vehicle before first use or
whenever operational status is restored.
Therefore, you may have to drive for a while
before precise route guidance is possible.
GPS reception
Among other things, correct functioning of
the navigation system depends on GPS
reception. In certain situations, GPS
reception may be impaired, there may be
interference or there may be no reception at
all, e.g. in tunnels or parking garages.
Input restriction
On vehicles for certain countries, there is a
restriction on entering data.
The restriction is active at vehicle speeds
above approximately 3 mph (5 km/h). The
restriction is deactivated as soon as the
speed falls below 2 mph (3 km/h).
When the restriction is active, certain entries
cannot be made. This will be indicated by the
fact that certain menu items are grayed out
and cannot be selected.
The following entries are not possible, for
example:
R entering the destination city and street
R entering a destination via the map
R entering in the vicinity of a city or via a
name search
R editing entries
R direct entry using the number keypad
Other entries are still possible, such as
entering points of interest in the vicinity of the
destination or current position.
