Navigation system (Navigation Computer): Description and operation (page 3 of 6)

System Settings Menu The system settings menu provides access to features that can be changed to suit market and personal preferences and to navigation system operating features. On European systems, the system settings menu also includes computer games and a currency converter. While the navigation computer is in the navigation mode, the system settings menu can be accessed by pressing the Nav button. Using the RH rotary control, the following features can be selected and adjusted: l TIME – Allows the navigation system clock to be set to local time as opposed to the Greenwich Mean Time (GMT) transmitted from the GPS satellites. The local time setting is necessary for correct navigation on routes with time restrictions and for Estimated Time of Arrival (ETA) calculations. The time can only be adjusted in 30 minute steps. l SAVE POSITION– Allows the current vehicle position to be saved and allocated a name in the navigation destination memory. l GAMES – Provides access to a selection of computer games. l LANGUAGE– Allows the navigation system language and voice (where applicable) to be changed. l ANIMATIONS– Allows the LCD animations to be switched on and off. l MEASURING UNIT – Allows the route guidance distances displayed on the LCD to be switched between metric and Imperial units. l ANNOUNCEMENT ETA – Allows the route guidance ETA announcement to be switched on and off. l CALCULATE EURO – Provides access to a currency converter.

While the navigation computer is in navigation, radio or CD modes, the user menu can be accessed by pressing and holding the tone button for more than 2 seconds. The user menu is displayed over two screens, which can be toggled between using the multifunction button. Using the appropriate multifunction button or the RH rotary control, the following settings can be selected and adjusted:

In automatic, the display will be positive or negative, depending on the setting of the exterior lamps. l Led – A Light Emitting Diode (LED) in the display can be set to off or blinking. When set to blinking, the LED flashes when the navigation computer is switched off. l M/S – Radio reception can be set to Stereo, Mono or Auto, to suppress interference and reflections and so optimise reception. Stereo is for exceptionally good reception conditions. Mono is for poor reception conditions. In auto, the normal setting, the navigation computer automatically switches between stereo and mono depending on reception conditions.

Screen 2 l Nav – Sets how audio navigation instructions are delivered. In onl, other audio sources are suppressed and only the navigation instruction is output to the speakers. In mixed, the volume of any other audio source is reduced and the volume of the navigation announcement is the same as the original audio source +/– 6 dB (adjustable). In independ, the audio source and navigation announcement can be set to independent volume levels. l Aux – Used to switch auxiliary CD AF connections between Aux mode on and Aux mode off. If no CD autochanger is installed, an external cassette or CD player can be connected to the navigation computer and powered by switching on the auxiliary CD AF connections. l Cmp – Allows a compass to be shown on the LCD when route guidance is not active. l BeV – Used to adjust the signal tone volume. Signal tones sound to confirm storage confirmation etc. and can be set between 0 (quiet) and +5 (loud).
