How to disable rear view mirror auto dim?

Everyone I start my truck, the auto dim feature is on and I have to manually turn it off every time.

Is there anyway to permanent disable it?
I have dark window tint and somehow the rear view mirror still dims the mirror so much it almost impossible to see out the back. I rather not have auto dim.

 

Two solutions come to mind:

• Unplug the wiring harness on the back (losing the compass functionality)
• Buy a replacement mirror with compass but without auto-dim

 

Hit the power button on the mirror everytime you start it or unplug it/remove fuse.

 

That damn compass is annoying too. Good luck OP

 

IF you manage to find the schematic, are you are good with probing, you can probably disable auto dim while leaving the compass function intact.

 

I just run a 300mm broadway mirror on top. Been a big fan of them for years.

 

Looks like I'll just turn it off manually, another thing to add to my pre flight check list along with ect button

 

I think there are two screws (maybe one) up in the sunglasses holder. If you take them out, the plastic piece pops out easily. That's where you can unplug the mirror

 

This. Is. Driving. Me. Nuts. I want the compass, but not this! Wondering if I just stuck some tape over it?
