Disclaimer: Installing an aftermarket radio in your Acura MDX will result in the loss of the center dash speaker and the factory handsfree bluetooth functionality. 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. Additional parts may be necessary to keep your factory steering wheel controls depending on the radio you are installing.
Notice: These DIY instructions are only meant for MDXs without navigation covering years 2007, 2008, 2009, 2010, 2011, 2012 and 2013. Replacing the radio in your Acura MDX requires you to connect 3 harnesses to your aftermarket radio harness. To complete the installation you must color match all the wires to your aftermarket radio harness. The MDX does not have an illumination trigger. This means you will not connect the orange or orange/white wire of your aftermarket radio harness to anything. You will have to manually dim the radio at night.
