Upon completion of the project I am having trouble with my touchscreen interface for the heat controls, turning off and on just randomly sometimes frequently sometimes not also I have no power to my USB is next to my SD card for navigation and I have a error on my navigation screen saying insert NAV SD card I’m wondering what the chances are that the panel there could cause the USB port to not get power or if those two modules are connected in anyway everything works properly on the touchscreen just not the touch panel, specifically the power button for heat controls, What should I be looking into replacing?
