Welcome to Justanswer
In order to remove the stereo there maybe caps over the holes if so then you will need the allen tool. But if not there will be 2 holes each side there is a tool but you can make a tool with a coat hanger and making it U shaped I have attached a image of the tool if needed. These sometimes will also need to be pushes out from behind the center console. Let me know if you need anything else. Danny
Its not the stereo I need to remove its the clock/radio display on top of the dash.
Ok this is a tricky guy but put a thin blade screw driver under the surround, and twiddle it while gentally pulling at the top - . once its off, unscrew the two screws holding the clock in and then unplug from behind, the light bulb is in the center - use a flat blade to twist and it will then drop out.
