@ahmed24 another question for you.
I noticed that my car doesn't go to the reverse cam when i put my car into reverse and doesn't indicate when my doors are open and stuff.
It does show info from canbus though and it does control my air con, so i know my canbus stuff is wired correctly.
What are your canbus settings? does your unit show your back up cam when you put your car into reverse? does it show when car doors are open and stuff?
