Yes I know it has been covered alot but I have a issue I can't seam to get fixed so let's start here
Car was fine eating lunch one day the screen stats to flicker then just goes black then shortly after that I turn the car off now I have no power to the top half the radio works fine. So I look thru every fuse on the car all are fine nothing that catches my eye. Get online start some reading well I tried the navi screen fix didn't work so I bought a new screen just the screen put it in still nothing? So next would lead me to belive the battery or alternator as I tried to start the car and it was dead so I replaced the battery and the alternator all new parts. So I'm kinda confused here would one think that the navigation ecu is just dead? Keep in mind it was flickering off then lost total power. If someone can help me figure this out without taking it to the stealership that would be much appreciated.

I'm no guru but my guess would be internal pcb mount fuse in the nav unit, that's assuming all car fuses are good. I'd start by metering power wires at nav connectors to verify unit is getting power

Sounds EXACTLY like what happened to me; only a different NAV unit (top half) fixed my issue : https://www.clublexus.com/forums/is-...n-related.html

What the hell?? This can't be a coincident? Can it. In this week, there are 3 people including me having this same issue. I just created a thread about it.
