I searched and did not see this posted previously... When the back-up camera is displayed on the screen, you can rotate the "ring" around the joystick to adjust the brightness. Mine was set pretty low, so I twisted to the right and the screen magically got brighter. Not a great trick, but it did help the somewhat useless image appear to be better.

 

LOL!

I just told my salesguy about that. RTFM FTW!!!!

He said he had been selling these for months and never realized it.

 

Nice catch. I missed that one.
I did look it up and it on pp275 of the manual.
Also when the dealer did the walk through when I picked it up, he did not mention it. And his demo took 25 minutes!

 

can also hit the day/night/off button to make it brighter when your headlights are on, try it at night
