No wonder you are having difficulty. Below offers the following opinions: 1) It is not on the passenger side foot well. 2) It is on the passenger side. 3) It does not exist. 4) You are really looking for the auxilary relay in the kick panel above the pedals. This is so laughable you are going to have to depend upon your lying eyes. My apologies in advance. I think part of the problem is that there was a change in the model in 1999 that is not picked up on in some sites. I will have to step back and let your own eyes find the truth of the matter. Below offers a lot of contradictions.

1999 MLs in the US did not have the aux fuse box in the passenger side foot well in spite of what you are told here: https://www.mercedesmedic.com/1998-2005-benz-ml320-ml350-ml500-fuse-box-location-diagram/ and in spite of what the manual says. Notice you don't find two plastic screws in the purported position.

The auxiliary relay panel is located above the lower kick panel above the pedals.

Maybe this will help: https://fuse-box.info/ The main fuse box: https://www.autofuseboxdiagram.com/35889-1999-mercedes-benz-ml320-fuse-box-diagram-2/ or https://www.carfusebox.com/mercedes-benz-ml320-1999-fuse-box-block-circuit-breaker-diagram/

Note that the following site proclaimes there IS NO auxilary fuse box. https://www.benzworld.org/threads/1999-ml320-auxiliary-fuse-box-location.3059219/ while MB MEDIC shows a picture of where it purportedly is on the passenger side!: https://www.mercedesmedic.com/1998-2005-benz-ml320-ml350-ml500-fuse-box-location-diagram/auxilary-fuse-box-location/

Fuse #11 is a 5 amp for the instrument cluster.

if your battery has died or you have had it changed radio could be locked. if this has not happend check the radio accesory fuses on fuse panel. the owners manual can help you locate it. if all the fuses are fine you will have to have the radio/nav unit serviced.

there are two...  one under the hood and one in the drivers kick panel. Also check the relays by swapping them.
