Remove the center control trim. To remove it, you need to remove the 6 T-20 Torx screws on both sides. You will find the screws holding the center control trim below it when you remove the side covers. Before you pull the center control trim, open up your armrest first. Then you can already pull the center control trim; when pulling, make sure that you also remove the cables connected below it and set it aside when you're done removing it from the vehicle.
This is how you remove the center control trim of the Mercedes Benz S Class.
Reinstall the control center trim. Once you have already put the radio on, also connect the cables connected on the control center trip and make sure that it is locked and you can already push it back in its original place. Then screw back the 6 T-20 screws below it. Remember that you will screw them on both sides.
