Hummer H3 2009
 
I have a new rear view mirror & it doesn't have the guidelines when I back up. My old mirror had the lines. How do you program them??

Welcome. Your question is NOT an FAQ and should NOT have been posted there.

Get a different mirror, like an H3 specific one. You could try turning it off, then back on again per the owner's manual???? Perhaps it is a setting in the head unit, not the mirror.

Take it back to whoever was overpaid to installed it?

Good luck.
