PIONEERSUBY Posted August 5, 2012 Share Posted August 5, 2012 lines indicate interferece with the rgb cable runnng from the right rear under the floor mounted nav computer. which runs to the screen. so first make sure that water hasnt found its way under the floor boards. leaking ice coolers are a common cause in the summer time. another common cause is an aftertmarket item a rear view canera by nav tool has been added. usually the factory back up camera is not the cause. but it is defintely that 18 pin plug that goes into computer that is getting interfence. try unplugging it and spraying with wd40 that should remove any water cxondesation on the connctor. you have to remove the trunk floor to get to the nav computer.
