Hi. Another question from me.
Is it normal, that the backup cam works only at very slow backup speed? My cam does it. At idle speed with foot on brake pedal it works great. Without braking and a minimum of throttle pedal pressure. the monitor switches to black and nothing is to see. I´d connected ( plus) on + from backup light and (minus) at the - cable from it. Is there any switch automatik in the radio?
