Upgrading to an aftermarket head unit?
You are going to need this kit!
Make everything work as it should with the use of this specially made adapter kit.
This adapter lets you connect your new car stereo to your Fiat 500's factory wiring harness. In addition to its power, ground, and speaker connections, the 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 audio system.
If you're installing a navigation receiver, the adapter 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 adapter also supports Retained Accessory Power (RAP) which keeps the music going until the door is opened. You can plug the steering wheel interface adapter (not included) directly into this integration adapter, and keep your 500's steering wheel audio controls working with your new car stereo.
We suggest also using the OEM Steering Wheel Control for Aftermarket Radios: http://shop.500madness.com/index.php?route=product/product&keyword=radio&category_id=0&product_id=2464
