Topic: 2012 Avalanche Rear veiw camera

[gary l]

I have a 2012 Avalanche LTZ with a really bad picture on my rear view  camera . I'm sure it can be improved by adjusting the brightness and contrast .  The owners manual ( on page 9-57 ) says to activate RVC and press menu to adjust contrast and brightness  , nothing happens ,  went to the dealer and they replaced the radio /dvd/nav unit  same problem   I talked to GM  and they said it "might" be a miss print in the manual and that "maybe" you can,t preform that function on 2012s    HELP

Why in the world would they replace the head unit? That has nothing to do with the back up camera.

My mirror has a crisp image even with my aftermarket nav tapped into it to also display on the touch screen.

The only thing I can think of is to check the connection on the back of the mirror. Then maybe look at the harness behind your upper console. To do that pop off the done light lens with a flat tool and then remove the 2 screws with a spline screwdriver. You'll be able to see where the wires for the mirror split off from the main harness. If it is all still wrapped neatly that means it hasn't been tampered with. Just look and see if something somehow melted or cut.

That's the extent of my knowledge. Good luck!
