Mercedes-Benz ML320. Manual — part 249

The digital components of the radio and navigation unit (A2/56) are interlinked via the digital data bus
( D2B ). Control data, audio signals and other information are transmitted between the various system
components via the digital data bus ( D2B ) Since some of the individual components operate with various data
formats or place different requirements on the transmission speed and transmission security, various bus
systems are installed.

SWITCH ON/OFF BEHAVIOR, FUNCTION - GF82.85-P-2006B

MODEL 163, 168, 170, 203.0 /2 /7, 208, 209.3 /4, 210 with CODE (353) Audio 30 APS

ON/off characteristics

The radio (A2) is switched on by pressing the "ON" button. The radio (A2) likewise switches On automatically
by rotating the ignition key (models 163, 168, 170, 208, 210) or transmitter key (A8/1) (models 203, 209) into
position 1 "circuit 15R ON", provided that it was switched on immediately before the last time "circuit 15R
ON" was switched off. However, if the radio (A2) was switched off last, only the following components are
activated with "circuit 15R ON":



Digital databus (D2B)



Continuous location finding

In this case the display on the radio (A2) remains Off. This allows quick availability of the system when the
"ON" button is then actuated.

Following each switch-on operation, the system returns to the state in which it was before it was last switched
off (e.g. navigation basic menu).

The bus systems and navigation processor for location finding (for quicker readiness for operation) are

already activated when the driver door is opened.

Switch off characteristics

The system is switched off by switching off at the "ON" button or when "circuit 15R ON" is switched off.

The unit switches off automatically after an hour, if when switching on the ignition key (models 163, 168, 170,
208, 210) or transmitter key (A8/1) (models 203, 209) has not been inserted in the ignition switch.

The data on the current navigation are stored for 12 hours after the radio (A2) is switched off.

Switch-on characteristics

Activation of entire system

When the ignition/starter switch is turned to position 1(c.15R, ON ) the display is switched on , if the radio
and navigation module (A2/56) has been switched on before the ignition key was removed the last time.

The radio and navigation module (A2/56) is now ready for operation. The system active before the last
switch-off (e.g. radio) is switched on and the corresponding basic menu displayed. If the radio and navigation
module (A2/56) has been switched off for longer than 60 min a warning display appears with general
specifications for using the system.

When a telephone call is received the radio and navigation module (A2/56) switches on automatically.

Behavior when rotary knob is pressed

The radio and navigation module (A2/56) can also be switched on the when the remote control key (A8/1) is
removed by actuating the rotary knob.

All functions are then available for 60 min . After expiration of 60 min the radio and navigation module
(A2/56) switches off automatically.

This function can only be repeated by actuating the rotary knob again.

Switch-off characteristics

The radio and navigation module (A2/56) can be switched off by turning the ignition key to position 0 c. 15C,
OFF ).
