On my 2020 I noticed that auto bright does no work when you turn on your fog lights. If I keep my dogs off, the auto high beams work fine. Weird if you ask me...
Check out Blendmount. I used them for my Valentine One install on my last 2 cars. They sell a nice mount to that fits right under your rear view mirror as well.

Newbie question here but can someone tell me what these are in the 2020 GMC Sierra truck bed? Is there an accessory that fits in for an additional tie down? I appreciate the responses!
