Can I easily access the rear of the radio ? on 1994 Mercedes-Benz SL500

How can I access the dashboard area to reach the rear of the radio of my 1994 SL500 to add my Sony 10-disc CD player? I would like to add this to my car as it is still a very good useable unit and the car does not have a cd player.

Buy a couple of radio/heater keys. They go in through small slots in the bottom of the units. Then simply slide the item out. If you remove power be sure you have the reset code.
