Description - RADIO - Alfa Romeo GT 2.0 JTS
The vehicle has a radio system comprising:radio (different versions are available: baseor CONNECT)front speakers (separate woofers and tweeters) located in the front doors;rear speakers (separate woofers and tweeters) located in the rear doors;radio supply cablesleads connecting the radio to the speakers;fishpole antenna with base mounted on the rear of the roof, coaxial cable and supply cable for aerial amplifier.
A radio with a cassette player (CC) is fitted on the "basic" version .A radio with a compact disc player (CD) can also be installed.If a built-in radio-telephone-navigator is fitted, the radio is incorporated in the unit.The radio is designed to operate the 10 -disc multiple CD-CHANGER located in the luggage compartment, on the right hand side.767if preparation for a cell phone is fittedor a radio telephone, then the aerial is the dual function type (radio/GSM); if a navigator is also installedthen the aerial has three functions (radio/GSM/GPS).It is also possible to fit a multi-polar cable connecting the radio to a CD player located in the boot, on the left hand side.

Description - RADIO - Alfa Romeo GT 2.0 JTS
The radio is a CAN node through which information is exchanged with the Body Computer and with the other electronic units.The radio receives the vehicle on signal via the CAN and is operated according to the following logic:if the radio is on and the vehicle is off, the radio switches off;if the vehicle is switched on and the radio was on previously, the radio remains on;if the vehicle is switched on and the radio was off previously, the radio remains off;if the radio is left on with the ignition OFF, it switches off automatically after 20 minutes;
The radio is equipped with an anti-theft system through the connection of the radio at the CAN with the Body ComputerWhen a new radio is fitted on the vehicle a connection is made with the Body Computer which requests the radio code: this code, supplied by the manufacturer, is entered using the numerical keys, the Body Computer memorizes this code and verifies it each time the radio is turned on.For more detailsor)- The radio also controls the volume linked to the vehicle speed: the volume increases and decreases in relation to the speed of the vehicle: this information reaches the radio node via the CAN.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 radio controls shown on the radio display are also duplicated on the instrument panel.
Operational description - RADIO - Alfa Romeo GT 2.0 JTS
The radio P20receives a direct power supply (7 of connector A) from the battery via the line for fuse F39 of the junction unit under the dashboard B2and maxifuse CPL of B99.The power supply reaches pin 4 of connector A with the side lights on.The CAN line arrives at pins 1 and 3 of connector A with which the radio P20is connected to the Body Computer M1and to the other system nodes.Pin 8 of connector A is earthed.The aerial P25 receives a power supply from pin 5 of connector A . The aerial is connected to the radio by means of the special coaxial cable.The following cables with signals for the speakers leave connector B:pins 5 and 6 to the left front speakers P35 and P45,pins 3 and 4 to the right front speakers P36 and P46,pins 7 and 8 to the left rear speakers P30 and P47,pins 1 and 2 to the right rear speakers P31 and P48,
Pins 10 and 11 of connector C are connected to the radio controls on the steering wheel: the connection takes place via the clock spring D47; the device which controls the control buttons receives an ignition-operated supply (INT) from the line protected by fuse F51 of the junction unit under the dashboard B2, whilst the reference earth arrives from pin 12 of connector C of P20.The connecting cable leaves connector C of P20 (pins 13-20) for the CD player P75 in accordance with the following connections: - Pin 13 asci bus from CDC to the radio - Pin 14 asci bus from the radio to the CDC - Pin 15 +12 permanent - Pin 16 +12V switched - Pin 17 digital earth - Pin 18 audio earth - Pin 19 left audio CDC - Pin 20 right audio CDCEngine compartment junction unit
