2. Functions2.1 NG radiosGeneral functionsThe radio functions can be activated via the operating unitand are displayed on the LC display or the BM. All systemcomponents are connected via the body/instrument bus. Allbutton or volume control operations are conveyed to therelevant components via the body/instrument bus.Radio operation without radio terminalIt is also possible to switch on NG radios when the radioterminal is switched off. This is not the case with BM radios.If the radio is switched on with the radio terminal off, it willswitch off again after 20 minutes. The radio can be switchedon again as often as required.Antenna diversityThere is no intermediate frequency connection on NGradios with antenna diversity (Business and Professional).The intermediate fequency is transmitted via the antennacable (RF lead) and analysed by the diversity unit.The diversity switches to the best possible antenna.Antenna diversity has been adapted to the new generationof radios. When the radio is in operation, the diversitycontrol unit is activated by the "RAD ON" signal.World frequency radioSpecific country signals can be set using the service mode.The settings are saved in an EEPROM. The settings can bechanged as often as required.9
Car/key memoryThe last station, the volume setting and the last audio mode(whether radio, cassette or CD mode is active) is storedaccording to the key. When the radio is switched on again,the volume will only be as high as the maximum start-upvolume set.The car/key memory function is deactivated by default.TimeThe time is displayed by pressing the clock symbol button,and can also be displayed when the radio terminal is off.ButtonsAll buttons are backlit. If a button is operated, thecorresponding function is executed by the NG radio, or amessage is transmitted to the body/instrument bus.Brightness controlThe light check module (LCM) and the light switch centre(LSZ) receive desired brightness information from themanual dimmer. The LCM/LSZ then processes the signaland puts the light information from the manual dimmer intooperation in two ways:- As a signal on terminal 58g- As a message on the body/instrument busThe light on/off signal is deduced from the body/instrumentbus data.The signal on terminal 58g is a PWM (pulse widthmodulated) signal. The voltage of the signal on terminal 58gis offset within the radio by the voltage from terminal 30.The message sent to the body/instrument bus conveys onlythe angle of rotation of the dimmer.10

Source management is carried out inthe NG radios.ResetNG radio reset is triggered by undervoltage and/or thewatchdog function (internal microprocessor monitor).Reset restarts the radio. It is the equivalent of switching offthe radio and then switching it on again.11
Voltage monitoringThe operating voltage (battery voltage ) is measured atterminal 30.Ub 17 V: the radio will be switched offUb 16 V: the radio will be switched on againGAL (speed-sensitive volume control)The speed signal for GAL control is made available to theradio by the body/instrument bus.GAL control is not implemented in the radio if a DSP(digital signal processor) is fitted.Body/instrument busThe following information, relating to the operating unit, isdistributed via the body/instrument bus:-Request terminal statusTerminal statusDimming / brightnessDoor / boot statusRequest diagnostic information (service mode)DiagnosisRequest unit statusUnit statusOn-board monitor operating unit buttonsOn-board monitor operating unit rotary knobsDimming / brightness requestE46 NG radios have anti-theft devices which are linkedthrough the body/instrument bus.At least one further bus component must be detectedbefore radio operation becomes possible.Diagnostic and service notesThe instrument cluster is the gateway betweenthe diagnostics bus and the body/instrument buscomponents.12
2.2 MIRSystem connectionsThe multi information radio (MIR) makes the display andoperation of the following components possible as asystem:- Navigation computer- CD changer- Instrument cluster/BC (on-board computer) functionsEach time the radio is switched on, the MIR detects whetheror not a navigation computer is fitted, and displays thecorrect menu screen accordingly.WithnavigationcomputerText and pictographs are generated by thenavigation computer. The data istransmitted to the MIR via the navigationbus.WithoutnavigationcomputerText and pictographs are generated by theMIR.On-board computer functions are not implemented on theZ8. There is no Check Control and therefore no warning oflamp failure, for example.MIR displays the outside temperature.Audio MixingAudio mixing enables the driver to listen to both music andnavigation information at the same time.13
Operational readinessIgnition lock The MIR is in sleep mode.The MENU button can be used to activate theposition 0MIR, to display the time for example.The MIR is activated when the driver's dooris opened.The message sent to the body/instrumentbus is processed once the body/instrumentbus has been activated. The MENU buttonfunctions and the display heating are carriedout/activated.The display temperature is monitored.Display heating is switched on depending onthe display temperature.Ignition lockposition Iand/or II(radioterminaland/orterminal 15)All button and rotary knob commands areprocessed and executed, or conveyed to theappropriate body/instrument buscomponent.Battery voltage UB (terminal 30) ismonitored for overvoltage/undervoltage sothat the display and/or the entire MIR can beswitched off if necessary. The LC displaytemperature monitoring device is active.LC displayThe screen has a definition of 64x120 dots (pixels). Thedisplay is backlit by LEDs.The following factors influence the display backlighting:- Ambient brightness (photosensor)- Dimmer position from the body bus message(with stabilised voltage)- Contrast (service mode)14
Display heatingThe display is heated to ensure the switching times of thesegments reach optimum values within the shortest spaceof time at low temperatures. The length of time the heatingis on depends on the ambient temperature. Thetemperature sensor is housed in the LC display.The display heating is switched on according to the displaytemperature, and under the following conditions:- The door must be opened, e.g. the driver gets in(ignition lock position 0)- Radio terminal on, body/instrument bus active- Display on, with ignition lock position 0MIR display heating will be switched on if the driver's doorhas been opened and the temperature is less than approximately 15 ºC.The current status is determined by the "driver's dooropen/closed" data supplied by the body/instrument bus,the terminal condition (radio terminal on/off) and thebody/instrument bus run-on-mode in ignition lockposition 0.If the temperature sensor is faulty (short circuit against UB ,plausibility), the heating is either not switched on, orswitches off straight away.This means that the display may take a little longer to buildat low temperatures.Time display with radio terminal offIf the MENU button is pressed with the ignition lock inposition 0, the MIR will activate the body/instrument bus. Itrequests the time from the instrument cluster and displaysit for 10 seconds. The MIR then returns to sleep mode.The MIR detects the terminal status via a message from theinstrument cluster.15
Rotary pushbuttons (DDK)The rotary pushbuttons have a locator light.The rotary pushbuttons are incremental and have norestriction in terms of the angle of rotation.The radio rotary pushbutton is used for volume adjustmentand for switching the radio on and off.The radio rotary pushbutton has 36 positions per rotation.The BM rotary pushbutton controls the system menuinterface.The BM rotary pushbutton has 16 positions per rotation.NAV-bus (navigation bus)The NAV-bus is a single-core bus. The same requirementsexist as for the body/instrument bus (message format, baudrate etc.).The information to be displayed is sent from the navigationcomputer to the MIR via the NAV-bus.Diagnostic and service notesThe MIR has two diagnostic functions. The diagnosticsdifferentiate between the radio and the operating unit.2.3 BM radioAudio MixingAudio mixing enables the driver to listen to both music andnavigation information at the same time.16
