i attatched a list of what the codes mean.

To remove the radio the clock has to come out. Its held in with clips. Use a small flat screwdriver and pop it out. Behind the clock is one screw. On the bottum of the radio trim there is 2 screws. Once all 3 screws are out the trim is just held in with clips. Get that out of the way and then you can remove the 4 screws that hold the radio in.
