Rear view mirror temp not working?

Has anyone experienced this? It's showing nothing on my rearview mirror.

Is it showing dashes or is the little screen not even working, if the screen is not working (no lights compass or temp) then it could be a fuse or a loose connection, if its just the temp that isnt working you should check the tempreture gauge wich is located under the hood, it either went bad or corrosion on the wires, keep us updated.

The little screen not working, I'll check this.
