CD changer broke. How to fix? (2006 ML320)

[Dick Dastardly]

Hi all, I recently picked up a 2006 ML320, which I really like, other than the CD changer in the glovebox stopped working yesterday. It looks like a disc is stuck as the screen just says something like 'Ejecting Disc 2' and there is a whirring noise and a red flashing light on the changer unit for the disc 2 slot, but nothing then happens.

I read online that you can take the fuse out and put it back in and that solves it. I can't find which fuse it is, and there isn't a fuse map with the car.

I did some research online but cannot find an answer. Any thoughts on the fuse it is or what else I can do?
