Turned steering wheel "tuning" button into "volume up" (down does nothing) and "source" button into volume down by simply switching the wiring plugs. True plug and play!! OE volume button does nothing either. Considering I drive with my left elbow on the top of the door panel my hand is at 11 o'clock, so no more having to move it for volume control, which is what I use most (only), other than cruise control.
