Heres how I did it:
1.) Disconnect negative battery cable so nothing shorts.
2.)Your gonna need phillips head screw driver and 3/8 inch socket.
3.)First take out the cup holders. There will be 2 screws on each side that will need to come off.
4.)Pull out the ash tray and remove 2 screws from that.
5.) Pull the dash trimpanel away from the dash to unclip the retaining clips that are on it.(Use force and it will come off.) Disconnect ciggarette lighter cables before pulling trim panel completely off.
6.)Remove the two 3/8 inch hex screws that are securing the factory radio to the dash.
7.) Slide the radio out and unplug 2 wire harnesses and disconnect antenna cable.
And now your ready to put that kickass head unit in!
(SORRY FOR THE VERY BIG PICTURES! DIDNT KNOW THEY WOULD BE THAT BIG!)
