Energy Management

All Infotainment control modules, including those for Navigation, are connected to the energy management system. This means the MOST-bus will shut off if there is a poor energy balance in the vehicle. Depending on the state of the battery there are different switch-off levels which have an effect on the different control modules. Navigation is no longer possible after the applicable level is activated.

Transportation Mode

The CD player inside the navigation control unit is locked when the vehicle is in transportation mode. The lock can be cancelled via an adaptation channel inside the control module or using a test program.

Pop-Out Button, Activating and Deactivating

In some cases, for example on rental cars, there may be a request to lock the pop-out button on the navigation control module. It is possible to engage the lock by changing the value on the appropriate adaptation channel.

Operating Requirements

• The MOST-bus will continue to run for a certain amount of time with terminal 15 ignition on and without pressing the button on the multimedia control head (E380). After this time period runs out or depending on the operating condition of the MOST-bus, either a terminal 15 ignition on signal must occur or the ON/OFF button on the multimedia system control head must be operated in order to continue the navigation.
