The XSVI-6515-NAV wiring interface from Axxess lets you connect your new car stereo to your Fiat 500's factory wiring harness. In addition to its power, ground, and speaker connections, this Axxess adapter also lets you keep your Fiat's factory Bluetooth, USB input, and the auxiliary input features. This versatile adapter can work with the basic Fiat audio system or with the upgraded Bose® audio system.
If you're installing a navigation receiver, the XSVI-6515-NAV interface also offers the parking brake, reverse, mute, and Vehicle Speed Sensor (V.S.S.) outputs that you'll need.
If you like that radio to keep playing after your Fiat's turned off, this interface also supports Retained Accessory Power (RAP) which keeps the music going until the door is opened. You can plug the Axxess steering wheel interface
(not included) direclty into this interface, and keep your 500's steering wheel audio controls working with your new car stereo. Warranty: 1 year.
