Getting the most powerful reverse led bulbs you can get makes a huge difference in the camera quality at night. I installed some 50W LED projection bulbs in my Denali and it made a significant difference. I believe the factory camera is overly sensitive to low light environments - before replacing the bulbs I could even tell a difference when it was cloudy out during the day.
For the auto bright feature - it is automatically turned off if your fog lights are turned on. Now as mentioned you can buy a quality $20 plug and play harness to act as a jumper (or there are several videos out there on how to make your own for a buck or two) that will turn on all your lights (lows, figs, and highs) when the highs are on....even when using the auto dim feature.
this is the harness I bought several months ago...works fantastic! And I drive a large portion of my miles at night....this combined with LED dogs and lows makes a HUGE difference in light output
