DESCRIPTION - NAVIGATOR - Fiat 500 1.3 Multijet

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 (Matrix version).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 preferences for the type of route to be followed such as, for example, motorway, toll roads, etc.;simulate the route 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 is connected to the GSM unit inside the control unit used for the connection of GPRS data for services such as: traffic in real time, navigation, etc.The stylus aerial and mounting is fitted at the rear of the roof: it performs three functions (radio/GSM/GPS) because it also incorporates the radio aerial.The position of the vehicle is identified through the analysis of GPS data and the speedometer and reversing signals coming from the vehicle received by the control unit via the C-CAN.The navigation maps are loaded onto the USB device connected to the USB port on the vehicle located near the cigar lighter housing.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 that manages the entire system receives the signals coming from the radio controls on the steering wheel (there are two special buttons for this function in addition to the radio controls).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 front 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 services.

FUNCTIONAL DESCRIPTION - NAVIGATOR - Fiat 500 1.3 Multijet

The Convergence control unit M162 receives a supply, at pin 16 of connector A, directly from the battery via the line protected by fuse F36 of the Body Computer M001 (pin 19 of connector E).The control unit M162 receives an ignition-controlled supply (INT) at pin 32 of connector A via the line for fuse F51 of the Body Computer M001 (pin 5 of connector E).Pin 15 of connector A of M162 is connected to the left rear earth C030.The Convergence control unit M162 (pins 14 and 30 of connector A) is connected, via the B-CAN, to the radio P020 (pins A3 and A1 of connector A), to the Body Computer M001 (pins 37 and 52 of connector F), to the instrument panel E050 (pins 5 and 6) and to the other system nodes.The Convergence control unit M162 is connected, via pins 1 and 2 of connector B, in the C-CAN, to the Body Computer M001 (pins 24 and 26 of connector D) and the other nodes receiving the vehicle dynamic signals (reversing, vehicle speed, etc.).The control unit M162 is connected, via pins 5, 22 and 21, with the radio P020 (pins 1, 2 and 3 of connector B) to manage the signals for the reproduction of the contents for the multimedia player function: AUX left, AUX right and AUX earth signals respectively.The Media Player USB socket P143 is connected to the Convergence control unit M162 (pins 3, 4, 19, 20 and 31of connector A) respectively, with signals: signal D+, reference earth, signal D-, 5V power supply and shielding.The hands-free microphone P026, located near the front courtesy light, is connected to pin 8 of connector A of M162, whilst pin 24 is prepared for the cable screening.The convergence control panel H136, located near the front courtesy light, receives (pin 6) an ignition-controlled power supply for activating its backlighting.The panel H136 is connected to the Convergence control unit M162. Specifically:at pin 2 it receives a reference earth from pin 11 of connector A;from pin 1 it sends an analogue signal for the buttons pressed (via the resistive divider) to pin 28 of connector A;at pin 4 it receives a positive signal for lighting up the LED signalling that the control is activated from pin 12 of the same connector.Connectors C (GSM) and D (GPS) of the Convergence control unit M162 are connected, by dedicated coaxial cables, to the aerial P110 which, on this version, includes the radio aerial function.The Body Computer M001 is connected to the radio controls on the steering wheel via the clock spring D047: Specifically:at pin 6 of D047 the reference earth signal from pin 35 of connector D of M001 is received;the signal is sent, from pin 4 of D047, for the MUTE/ESC, WINDOWS logo, VOL+ and VOL- controls (located to the left of the steering wheel) to pin 50 of connector D of M001;the signal is sent, from pin 3 of D047, for the SOURCE/OK, TEL/MAIN, SCAN+ and SCAN- controls (located to the right of the steering wheel) to pin 52 of connector D of M001;The Body Computer M001 receives a direct battery power supply (pin 1 of connector A) protected by fuse F01 of the engine compartment junction unit B001 (pin 18 of connector B); it also receives an ignition-controlled supply (INT) at pin 11 of connector E.The Body Computer M001 is also connected to the driver''s dashboard earch C015 via pins 9 and 10 of connector E.
