The vehicle may be equipped with a radio system with a HI FI acoustic system composed of:- radio;- wiring (speakers and radio);- speakers in the mirror triangle (tweeters);- speakers in the front doors (mid-woofers);- speakers in the rear door panel (tweeters);- speakers in the rear doors (mid-woofers);- audio amplifier with sub-woofer speaker located in the boot on the right hand side;- AM/FM aerial coaxial cable;- aerial mounting and stem.With this acoustic system, the operation of the speakers (tweeter and mid-woofers) is managed directly by the amplifier/sub-woofer system to produce excellent sound in all areas of the passenger compartment.In this configuration the radio is a CAN node through which information is exchanged with the Body Computer and the other electronic units, providing the customer with a series of functions, including:- automatic switching off 20 minutes after the key off to protect the battery;- control of the dimmed lighting in the radio display with the side lights on;- volume control dependent on the vehicle speed (SVC);- controls on the steering wheel (where fitted).The radio, available in two different versions depending on customer requirements, can have a traditional CD player or CD MP3 player (compressed files).The radio has a security system with a four digit identification code on a card that is handed over to the customer when the vehicle is received when there is a factory-fitted radio.The above code should be entered every time the battery is disconnected to prevent it being reused on another vehicle.It is also possible to fit a multi-polar cable connecting the radio to a CD changer located in the oddments pocket on the passenger side.This configuration involves preparation for a mobile phone with hands-free kit.Some versions are equipped with controls on the steering wheel (6 button version): these make it possible to replicate some of the commands which are acquired in the same way by the actual radio. The functions are:- change/preset CD track or radio station (forwards);- change/preset CD track or radio station (backwards);- SCR (switch listening source);- VOL+ (increase volume);- VOL- (decrease volume);- MUTE.For more details, See descriptions 5570 ACCESSORIES
