2006 2007 2008 2009 2010 2011 2012 Honda Civic Aftermarket Radio DIY Wiring Instructions

Disclaimer: The steering wheel controls that work with the aftermarket radio are volume up, volume down, next track, previous track and mode. 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 Honda Civics without navigation and with or without the premium sound system. To complete the installation you must color match all the wires to your aftermarket radio harness. The blue/white wire of your aftermarket radio must be connected to the blue/white wire on the 20 pin connector otherwise you will have no sound. If you are having trouble please call or text 877-542-2872.
