Ok, its installed. The harnesses are plug and play to the old Sony, but thats where it stops. This radio is what a marine radio should be like. It has a huge rubber grommet to seal the hole the radio slides in. Here is what I had to do.....
Take off the faceplate of the oem radio. You will also go ahead and remove the two black screws on top and bottom of the radio. You will not need these anymore.
Then take an aftermarket radio removal tool, (or something thin, sturdy and flat) and place it in the center of the sides of the case. This will release the radio. Make sure you tag each wire so you know where it goes on the new radio.
You will also see your three amps.
Now pull out your old radio leaving the power harness from it behind.
^^Thats what you should end up with.
Now go inside the storage compartment and pull out the mounting cage. You should have a nice clean hole.
Now follow the mounting instructions for the new radio. Your going to drill 4 holes on the top using the radio as a template, and two holes on the bottom. Slide in the radio, and screw down securely. There is a strap (metal) that you will have to find a place to secure the radio from swaying. I used the on directly on top of the radio. Its the bolt that holds the glove box hatch.
This is the finished product working.
