Disclaimer: Installing an aftermarket radio in your Acura MDX will result in the loss of your factory rear entertainment, dvd player, factory hands free link and external cd changer. You will also lose the factory navigation audio prompts. Your navigation touchscreen will still work. 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 nor will 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 MDX if you have a 2001, 2002, 2003 or 2004 there is only one connector that will need to be wired to your aftermarket radio. If you have a 2005 or 2006 Acura MDX with navigation then 3 connectors must be wired. If your 2005 2006 Acura MDX doesn’t have navigation then you will only need two connectors. To complete the installation you must color match all the wires to your aftermarket radio harness.
