DESCRIPTION - NAVIGATOR - Fiat BRAVO 1.9 JTD 8v
The Blue & Me system, alongside the Bluetooth technology for using a mobile phone in the vehicle, is also available with a navigation system for reaching a destination speedily and safely.One is guided to the destination by voice messages and instructions on the instrument panel display.The navigator makes it possible to:- enter a new destination- navigate to a point of interest (which can be selected from a list of categories such as, for example, hotels, restaurants, airports, railway stations, etc.)- acquire journey information (arrival time, distance from the destination, vehicle position)- recover the last destinations memorized- set preference for the type of route to be followed such as, for example, motorway, toll roads,- simulate the ruote to a prearranged destination in advance.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 GSM aerial, on the other hand, is connected to the GSM unit inside the control unit, used for connecting the GPRS data for services such as traffic in real time, navigation, etc. The stylus aerial is fitted at the rear of the roof: it performs three functions (radio/GSM/GPS) because it also incorporates the radio aerial.Vehicle position is identified by analysing GPS data together with speedometer and reverse gear signals received from the vehicle.The navigation maps are loaded onto the USB device connected to the USB port on the vehicle.The control unit that manages the entire system is a CAN node via which information is exchanged with the Body Computer, the instrument panel and the other electronic units (e.g. the navigation system downloads information from the odometer, reverse engagement signal etc. ).The control unit is also connected to radio controls on the steering wheel (two special keys for this function are provided in addition to the radio control keys).The entire operation of the system is also managed by voice commands, picked up by the microphone near the front courtesy light.There are three additional control buttons in the trim in front of the centre courtesy light:- NAV: launch of the Navigation Menu - display of incoming information with navigation activated- SOS: access to Roadside Assistance Services- Info: access to infomobility servicesFor more details on system operation
FUNCTIONAL DESCRIPTION - NAVIGATOR - Fiat BRAVO 1.9 JTD 8v
The Bluetooth control unit M162 is supplied directly at pin 16 of connector A from the battery via the line for fuse F39 of the junction unit under the dashboard B2.The Bluetooth control unit M162 receives an ignition-controlled power supply at pin 32 via the line for fuse F51 of the junction unit under the dashboard B2.Pin 15 of M162 is earthed.The CAN line that connects the Bluetooth control unit M162 to the radio P20, the Body Computer M1, the instrument panel E50 and the other system nodes reaches pins 14 and 30 of M162.The Body Computer M1 is connected to the radio controls on the steering wheel via clock spring D47: pin 27 of connector H of M1 receives the signals for the buttons on the right of the steering wheel, whilst pin 15 of connector H of M1 receives the signals from the buttons on the left of the steering wheel.The Body Computer M1 receives a direct supply from the battery via the line protected by maxifuse B99 at pin 18 of connector F of the interface with the junction unit under the dashboard B2; the ignition-controlled supply (INT) reaches pin 9 of connector F of the interface with the junction unit B2.The Bluetooth control unit M162 is connected to the radio P20 - connector E - from pins 5, 22 and 21 with the AUX left, AUX right and AUX earth signals.The USB port P143 is connected to the Bluetooth control unit M162, to pins 3, 4, 19, 20 and 31 respectively, with signals: signal D+, reference earth, signal D-, 5V power supply and shielding.The handsfree microphone P26 is connected to pins 8 and 24 of M162.The navigation controls H135, located next to the front courtesy light, receive an ignition-controlled supply at pin 6 via the line for fuse F49 of the junction unit under the dashboard B2; pin 5 is earthed.The command for the signalling LED reaches pin 4 from control unit M162, the referenc earth reaches pin 2 from pin 11 of M162, whilst the analogue signal for the buttons pressed leaves pin 1 for pin 28 of M162.
