SummaryThe backlight bulb for my climate control panel burned out. I needed a "radio removal tool" to release the control panel from the console. These keys will "unlock" the latches holding the radio to the console. This was quickly put together based on a picture at http://www.benzworld.org/forums/w210-e-class/1514205-tool-key-pull-out-radio-unit.html See more pics here: http://www.benzworld.org/forums/w210-e-class/1439298-front-console-climate-control-lights.html Instructions found on Youtube: http://www.youtube.com/watch?v=7nrK5KO8EFoInstructionsThe keys are thin so print with 100% infill for strength. Just work methodically and gently. These keys will latch onto the radio - after a few gentle wiggles, you should be able to slide the radio out with very little effort! Don't force pulling the radio out. Since the keys will unlatch the radio, you could then use other tools to assist the removal if needed. In my case, it moved out very easily.
