DESCRIPTION - RADIO - Fiat 500 1.4 16v

The vehicle is equipped with a radio system comprising:radio (with CD / MP3 player);2 mid-woofer front speakers located in the doors;2 tweeters located in the front pillars near the rear view mirror triangles;2 full-range rear speakers located in the rear side panels;cables connecting the radio with the speakers;aerial with support fitted at the rear of the roof with a coaxial connecting cable.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 navigation with maps) the controls on the steering have 8 buttons.The radio is an integral part of the radio phone and navigation system.For more details,
