GF82.61-P-0001-07TXB Auto Pilot System (APS), Switch On And Switch Off Characteristics
- with CODE (525) MB Audio 50 APS radio
- with CODE (511) Audio 50 APS with DVD changer
General information
The switch on/off characteristic comprises the following subfunctions:
^ Activating the overall system
^ Conduct when pushing "ON" button
^ Switch-off characteristics
^ Switch off characteristics at undervoltage
^ Switch off behavior (run-on mode) when the destination has not been reached
Activating the overall system
When the vehicle is opened, all data bus systems are activated to ensure a faster switch-on procedure. After inserting the transmitter key (A8/1) into the EIS [EZS] control unit (N73) and rotating to position 1 ("Circuit 15R ON") the display of the radio control panel and navigation unit (A2/56) is switched on, provided that it was on when the transmitter key was last removed
The system that was active before the transmitter key was removed last (e.g. radio tuner) is switched on and the corresponding start menu is displayed. If the radio control panel and navigation unit was switched off, a warning notice is always shown with general information on using the system.
Conduct when pushing "ON" button
The radio control panel and navigation unit can be switched on by pressing the "ON" button, even if the transmitter key has been removed ("Circuit 15R OFF"). All the functions are then available for t = 30 minutes The radio control panel and navigation unit then switches itself off automatically.
Switch-off characteristics
The radio control panel and navigation unit is switched off when the transmitter key ("Circuit 15C OFF") is removed. The run-on time of t = 30 min. (standby) of the navigation system starts.
During the run-on time, all the important localizing parameters remain stored. The audio system's run-on time can be configured and is set when the radio control panel and navigation unit is installed in the factory. The switched-off radio control panel and navigation unit is always in "standby mode" if the Controller Area Network bus class B (interior) (CAN-B) is active.
Switch off characteristics at undervoltage
In the case of undervoltage of the battery (G1), a message is shown on the display of the radio control panel and navigation unit asking for the engine to be switched on. If the engine is not started, another warning appears after t = 3 min saying that 10 s remain to start the engine before the radio control panel and navigation unit is switched off.
If the radio control panel and navigation unit has shut off and the on-board voltage increases again, the radio control panel and navigation unit does not automatically switch itself on again.
The radio control panel and navigation unit can be switched on again manually. The warning procedure then runs again, until the cause for the undervoltage is rectified.
Switch off behavior (run-on mode) when the destination has not been reached
If the destination of the route guidance has not been reached, the navigation system in the radio control panel and navigation unit acts as follows when the engine is shut off:
- Navigation remains active up to t = 30 min. (e.g. refueling stop). Navigation continues from where it left off after restarting the vehicle.
- After t = 30 min up to a maximum of t = 2 h, the radio control panel and navigation unit remains in "sleep mode". The route is re-calculated after restarting the vehicle and the navigation continued.
- After t = 2h a prompt is displayed after starting the vehicle asking whether the route should be recalculated.
"YES" = Route is calculated again.
"NO" = Navigation will cease.
