A road map navigation system reveals the vehicle''s position on a map (showing town streets and main roads/motorways) at every moment and pinpoints it on the CONNECT display.In this way the driver is guided to the required destination step by step by means of voice messages and visual information. The system also provides additional information for reaching general services, namely: hotels, carparks, restaurants, chemists, service stations, hospitals, ALFA ROMEO service outlets, railway stations, airports etc.The navigation system uses GPS (Global Positioning System) satellite localisation technology and is fitted, when ordered, in the integrated radio-phone-navigation system known as "CONNECT NAV +". The navigation CD-ROM drive is located in the unit.The GPS consists of an aerial that allows the vehicle to be GPS satellite-located: the aerial is connected to a receiver located in the integrated unit by means of a special shielded cable. The stylus aerial is fitted at the rear of the roof: it performs three functions (radio/GSM/GPS) because it also incorporates a GSM aerial and a radio aerial. Vehicle position is identified by analysing GPS data together with speedometer and reverse gear signals received from the vehicle.Some versions are equipped with a series of buttons on the steering wheel: these are used to send out radio and also phone commands.Other control buttons are located in the front courtesy light.For more details on phone operation See descriptions 5580P CONNECT PANEL
