The mirror on my vehicle is causing the radio to turn off whenever I press the mirror switch. The radio works fine as long as the mirror switch doesn't get turned on. The mirror itself doesn't work.

The mirror is brand new.
Fuse and relay are good as far as I know.

Anything that I can do?

Hello, this sounds like an interesting issue. I see this rear-view mirror has an automatic darkening that works off a Photo type sensor. So, are you having an issue with the outside mirror switch on the left and right door that is affecting the radio function? I don't see any kind of switch for the rear-view mirror in the wiring diagrams.
Also, what kind of Radio setup do you have? There is a 6 Speaker Sound system without Navigation, a 10 Speaker System without Navigation, or a Sound System with Navigation.
It also looks like some models have a Rear Camera on the Liftgate. So, if you can give some more details about what you have in your vehicle, we can check for some areas where they might have some sort of connection together. It sounds like there might be a Ground or Power wire that the Mirrors and Radio share. Maybe we can get the mirror(s) functioning again for you too.
