Does this help ?
First thing you will need is the keys to remove factory head unit , it will slide out and unplug from the rear , make sure you take your cds out first or in this case remove cartridge from the stacker.
Remove the glove box , the pin needs to come out from inside the drivers side at the rear , then carefully push the rubber tab in and the glove box will fall out.
The panel below the steering column unclips and swings down with the same clip as the glove box then it will also come out.
The 2 sides of the console have screws going up into the dash and 1 at the rear.
The passenger side end of the dash has 1 cover plate with 5 screws in it and the end of dash plate has 3.
The panel above the glove box has 10 screws holding that up , it will then drop and the wiring harness can be unplugged from the back of it.
The panel around the shifter has 2 screws hidden under the ashtray , once they are out the rear of that panel will unclip upwards and you can unplud the electric windows if you have them.
There is 2 screws at the base of the main dash surround that hold the ashtray then that will also come out.
The main facia has 2 screws going upwards above the instrument cluster.
There is 3 either side of the steering column then that main facia will unclip and you can remove the plugs from the back of it.
The center console has 2 10mm nuts inside it.
There is 1 screw either side of the center console in the middle.
There is 4 screws around the area where the cigarette lighter is.
The main surround has screws everywhere , once they are all out you will need to unplug the cigarette lighter and that piece will lift out.
Everything going well it should start lookign like this
You will have a pile of panels that looks like this and a handful of scrwws like this
The screen I had to fit is a Pioneer 2 DIN DVD 6 disc screen , slide it in to where you want it , in this case I had to lift it 6mm to be central with the face , I then marked where 2 holes will line up drill it out.
Once you have bolted the deck up fit the facia back on the check that it lines up correctly , the facia is usually supplied with the head unit and may need to be cut down to fit flush.
The below pic shows how far off the front lip the deck sits as a guide to where you want your facia.
The deck itself is about 4mm narrower than the steel box in the car , instead of doing the bolts up that tight it bends the head unit I glued a 2mm washer on either side as a spacer.
Now all you need to do is wire it all up and test that it works before you put all the dash back together
