2004 2005 2006 2007 2008 Acura TL Aftermarket Radio DIY Wiring Instructions

Disclaimer: Installing an aftermarket radio in your Acura TL will result in the loss of the center dash speaker and the factory hands free link. The center speaker is not retained so you will lose factory navigation audio prompts. Also the steering wheel controls that work with the aftermarket radio are volume up, volume down, next track, previous track and mode. The call buttons will not work with the aftermarket radio or the navigation prompt buttons on the steering wheel. Additional parts may be necessary to keep your factory steering wheel controls depending on the radio you are installing.

Notice: When replacing the radio in your Acura TL if you have a 2004, 2005 or 2006 there are only two connectors that will need to be wired to make your aftermarket radio work. If you have a 2007 or 2008 Acura TL then 3 connectors must be wired. The white connector behind the radio is not used. To complete the installation you must color match the wires to the wires on your aftermarket radio.
