Interior LED's
 

I've searched but found nothing. I have replaced all interior bulbs to LED's in my 11' S550. The only ones I'm having trouble with is the map lights on the bottom of the rear view mirror. Anyone have an idea on how to get to these bulbs? The round lens rotates and looks like it's marked locked and unlocked. But I can't figure out how to remove it.

Anyone swap those out?

Thanks...
