This guide will follow up on the removal of the front dash panel removal and show you how to access the actual stereo head unit.
Using a panel tool or long flat head screwdriver, pry the wood grain trim off and release the clips. Be careful on the thin sections below the head unit as to not snap the trim.
Detach the wiring harness from the back of the air conditioning control unit by pushing down on the top middle tab and pulling apart using a screwdriver for leverage if necessary.
Unscrew the four screws from the sides of the deck, circled here.
Pull the head unit straight out gently until the two wire harnesses are exposed.
Push down on the tabs and remove the wiring from their blue and white harnesses.
These two are harder to remove than the others so do not be afraid to use force, or a flathead screw driver for leverage to pop them out.
As long as you are pushing the tab and force it out at a straight angle neither the plastic nor the wiring will be damaged.
