Hello Have the radio of Audiovox vme 9309ts now installed in my Omi Facer bJ.08/2000. The radio goes on and everything runs but when I turn it off it loses all the transmitters. Then the fan on the back was so loud that after long back and forth I separated the fan with the side cutter. Maybe someone has an idea which cables I have to switch so that the radio keeps the transmitters and settings. Oh yes, someone has a solution in relation to the fan ? Greeting
