JY-MO002N3N -Mazda 3 BK (2004-2008) after installation problems
just got installed the new joying HU JY-MO002N3N and i have two major problems

the first one - in my car there is an small screen for the radio and the AC and it should be on the HU but for some reason its not getting in to the joying screen. the small screen is getting data from the redio (Phone, Video. Music and even the radio station) but not the clement date
did enyone know if just CAN bus problem or something bigger?

another problem is that I don't have a revers camera but when I put the car in revers its trying to display an image. where I can change it? I have search in the settings but didn't found it
