Audio Wiring Harness. Fit Years 2005 - 2007. Take your tunes on the road! Now you can connect portable audio players (MP3 iPod iRiver SanDisk etc.) plus portable CD and cassette players right to your in-dash radio. Just plug your player into the harness - a 3.5mm stereo connector provides the interface so you can listen to music through the radios speakers and control the volume. Audio connection is housed securely in your vehicles glovebox or center console. Dealer Installation Recommended. As this is an FM modulated connection using the 88.3FM band some models require an additional antenna adapter.
