LimeyZ Posted March 5, 2009 Share Posted March 5, 2009 Here is what I know about the Navigation problem I'm having. Everything was working fine until I was probing wires to do my alarm install using a volt meter. I unplugged the ECU to test some wires and when I plugged it back in my nav stopped working. When I turn the car on now the display comes on, but it's black with nothing else. The nav system makes two beep sounds. the first is a long beep and then a short beep. I have an updated nav DVD that I need to run a software CD for it to work. I have tried reloading that, but it didn't help. I have also tried putting the original DVD back in there and still no change. Any info you have would be great. I would hate to have to take my Z to the dealership.
