DESCRIPTION - RADIO - Fiat 500 1.2 8v
A HI-FI system with 6 speakers, a power amplifier and a subwoofer is available on request.The system has been developed specifically for the vehicle; the acoustic properties of the passenger compartment have been carefully studied so that the amplifier, speakers and subwoofer are perfectly suited to the vehicle: optimum listening is available in any part of the passenger compartment.Depending on the basic system, the HI-FI system includes:dedicated front speakers (mid-woofers in the doors and tweeters in the pillars) and rear speakers (full-range in the side panels);a subwoofer containing a power amplifier located under the right front seat;a 4 channel amplifier (4x30W) located in the right rear side panel.
The other system components (radio, aerial, etc.) are the same as for the standard system.In this configuration the radio is a CAN node through which information is exchanged with the Body Computer and with the other electronic units.The radio is equipped with an anti-theft system through the connection of the radio at the CAN with the Body Computer; it also manages the volume control linked to the vehicle speed via the CAN: the volume increases and decreases in relation to the speed of the vehicle.Some versions are equipped with a series of buttons on the steering wheel: these make it possible to replicate some of the commands which are acquired in the same way by the actual radio.The following functions are present on the steering wheel:change/preset CD track or radio station (forward);change/preset CD track or radio station (backward);SCR (switch audio source);VOL+ (increase volume);VOL- (decrease volume);MUTE.
On versions with Bluetooth and Blue & Me (with a map navigation system) the controls on the steering wheel have 8 buttons.The radio is an integral part of the radio-telephone and navigation system.For more details,
FUNCTIONAL DESCRIPTION - RADIO - Fiat 500 1.2 8v
The radio P020 (pin A4 of connector A) receives a direct power supply from the battery via the line protected by fuse F36 of the Body Computer M001 (pin 12 of connector E).Pin A8 of connector A of P020 is connected to the driver''s dashboard earth C015.The radio P020 (pins A1 and A3 of connector A) is connected via the B-CAN to the Body Computer (pins 22 and 17 of connector D) and to the other system nodes.The radio aerial P025 (or, on versions with Blue & Me, the triple function aerial P110) is connected via the coaxial cable to connector C of P020.The amplifier located in the subwoofer P092 receives a direct power supply from the battery (pin 3) via the line protected by fuse F02 of the engine compartment junction unit B001 (pin 25 of connector B); pin 7 of P092 is connected to the left rear earth C030.Pin 8 of P092 is connected to the radio P020 (pin A5 of connector A) which supplies a positive signal to enable the subwoofer to be switched on. The same signal is supplied to the amplifier P070 (pin 8 of connector B).The amplifier P070 also receives a direct power supply from the battery (pin 1 of connector B) via the line protected by fuse F02 of junction unit B001; pin 2 of connector B is connected to the left rear earth C030.Connector A of the radio P020 also provides the connection for the signals with the amplifier P070 and with the subwoofer P092. Specifically:from pin B1 (+ right rear speaker), to pin 9 of connector B of P070 and to pin 2 of P092;from pin B2 (- right rear speaker), to pin 3 of connector B of P070 and to pin 5 of P092;from pin B7 (+ left rear speaker), to pin 10 of connector B of P070 and to pin 1 of P092;from pin B8 (- left rear speaker), to pin 4 of connector B of P070 and to pin 4 of P092;from pin B3 (+ right front speaker), to pin 7 of connector A of P070;from pin B4 (- right front speaker), to pin 1 of connector A of P070;from pin B5 (+ left front speaker), to pin 8 of connector A of P070;from pin B6 (- left front speaker), to pin 2 of connector A of P070.
The following cables with signals for the speakers leave connector A of P070:from pins 6 (+) and 14 (-) to the driver''s front speakers P035 (mid-woofer) and P045 (tweeter);from pins 11 (+) and 10 (-) to the passenger side front speakers P036 (mid-woofer) and P046 (tweeter);from pins 5 (+) and 4 (-) to the left rear speaker P030 (full-range);from pins 12 (+) and 13 (-) to the right rear speaker P031 (full-range).
The radio controls on the steering wheel are connected to the Body Computer M001 via the clock spring D47. 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, 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, SCAN+ and SCAN- controls (located to the right of the steering wheel) to pin 52 of connector D of M001.
On the Bluetooth and Blue & Me configurations, connector B of P020 is connected to the Convergence control unit M162.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 power supply (INT) at pin 11 of connector E.The Body computer M001 is also connected to the driver''s side dashboard earth C015 via pins 9 and 10 of connector E.
