Hello! I’ve been a member but I haven’t really posted. I have a 2004 QX56. I am the 3rd owner my brother in law being the second one. It currently has 267,000 and counting. Wherever I turn off the suv the nav screen stays lit with a white light. I have to disconnect the battery in order to get it to go off. Sometimes It will work so I’ll be able to use the rear back up camera and the radio. Then it will just go off and not work again for a while. It comes and goes. Any body rose else had that issue?
