Went to the dealership last week for an oil change and asked them to change my ambient light bulb in the rearview mirror. The brown/orange light that comes on at night in-between the two map lights. The dealership claims I don't have a light there, only two map lights and that's it. Now the problem is I can't exactly remember for sure if I have it there or not since I can't remember when it was working last. I have the orange glow of ambient light in my feet area and the passenger's footwell, so I figure I must have it in the rearview mirror. My wife's 2008 C300 has it in her rearview mirror. How do I prove it to the dealership that I'm suppose to have an ambient light in the bottom of the mirror? Also it looks like the mirror has to be completely removed to get at any of these bulbs, including the map lights. So It doesn't look like an easy DIY.
Please help.

my 2010 ml320cdi has it. it serves to illuminate the area where we have cupholders. as you said it is orange and in between map lights.
