PCM SYSTEM N 01 (Porsche Infosystem Navigation)
Basic functions of the PCm

- Audio (tuner with cassette drive)

- GSm telephone with SIm card reader

- Navigation

- On-board computer

- A/C display

Navigation

The highly accurate satellite-based navigation system permits rapid and sure guidance to an input destination in areas for which a digitized road map onCD-ROm is available. Route guidance is realised by means of driving instructions with voice output in various selectable national languages, supportedby arrow or map displays on the screen.

Audio

Buttons for selecting the various audio sources (Am/Fm tuner, cassette, CD) are located on the left side of the front panel.

The RDS names of the stations of the current memory level stored at the station buttons are shown on the function display offered during Fm radiooperation. The desired station can thus be selected quickly.

In addition to the station-search function, the system also has an autostore function in Fm operation. This function assigns the station buttons andautomatically adds the station names described above so that they are permanently visible.

The main pages for all audio sources include the item Set. If this item is selected, the system offers adjustment possibilities for treble, bass, balance,fader, speed-dependent volume control (GAL) and loudness.
If the Digital Sound Processor (DSP) option has been installed, further functions fur optimum sound adjustment are available.

In this case, it is possible to select conventional treble/bass adjustment or a 7-band equalizer. Furthermore, high-fidelity audio patterns can be selected.Finally, the user can also define individual audio patterns according to his or her own taste.

Telephone

The GSm telephone offered for the European region fulfills all demands with regard to practical operation, voice transmission arid reception sensitivity.
Individual functions:

-

GSm telephone with transmission power2 W

- Digital handsfree use (echo compensation) via the audio loudspeakers and an external handsfree microphone

- Audio mute function during a conversation in handsfree mode

- Integrated SIm card reader

- Emergency call possible even without SIm card

- Separate passive handset can be connected

- SmS (Short message Service) reception with the possibility of directly selecting telephone numbers present in the message section

- Network operator and field strength are displayed

- Existing network operators are displayed; manual or automatic selection is possible

- PIN query can be switched on/off (if supported by service provider), PIN can be input/changed

- Copying and rental of phone cards.

On-board computer

Some functions of the on-board computer display are linked with the data of the navigation unit.
The time is set automatically according to the data determined by the GPS receiver; thus, the only work required involves setting the time zone once.

The route to the destination is known if the route guidance function is activated in the navigation unit. The length of this route is displayed as the distanceto the destination. The range display allows an estimate about whether the fuel supply is adequate for the remaining distance. The estimated time ofarrival is calculated on an individual basis according to the driving style and the planned route: The navigation unit informs the on-board computer aboutthe different road categories along the route and the length of these road sections.

The on-board computer calculates a different individual average driving speed for each road category. This information is used to calculated the plannedtime of arrival -if no traffic-related delays occur -on an individual basis. The on-board computer also supplies standard information, for instance theaverage consumption, average speed, distance travelled, and elapsed driving time. The outside temperature is adopted from the instrument cluster. It ispossible to set a limit that triggers a visual and audible speed warning.
It is also possible to switch to different units of measure and languages and adjust the display contrast.

The A/C function is limited to the display of data transferred from the air-conditioning regulator.

- Fan setpoint

- Passenger compartment temperature setpoint

- Air distribution

- Status display (automatic system, defroster, A/C compressor, air circulation)

The display is activated automatically whenever a manual adjustment is made on the air conditioning regulator or the A/C function is specificallyselected.
