Rear View Mirror Display
 

I have a 2020 Touring Z. I don't need the camera in the rearview mirror. What pin do I need to remove to turn it off?

You could just unplug the connector from the rear of the mirror. Buuuuut, the dimming/homelink/navigation wouldn't work either so... no clue.

You should be able to find that information in the FSM. There are links on the forum or in some users' signature (look for SouthArk posts)

Yep

There's no pin info for the screen in the rearview mirrors in the FSM. Actually, I couldn't find any mention of the rearview screen at all in the FSM. Just the NAV system.

I think the best way to accomplish this, without mucking with the factory wiring and originality of your car, is just to go to eBay or something and buy the Gentex mirror with homelink that does not include the LCD screen. Those are cheap and plenty. Plug and play and most importantly easily reversible.

I used a voltmeter and found the wire. Mine was white with a blue stripe.
