When is start the car it shows Lexus logo but nothing after that , only REVERSE CAMERA AND NAVIGATION PORTION IS BLANK AND when And I did the diagnosis test and does not have any error on all but if I go to navigation check the orange rectangle comes on top left corner and nothing happens and camera check option is solid car and I can’t click on it everything else all are ok , please advise what should I do now to get this fixed , I did order the used DVD ECU unit from eBay , do you think it will fix it ?



I really need a solution now I am tired doing stuff

 

You already have a thread going in the LS 3rd Gen forums. I think that is probably the best place to seek help. If that's not working out, I would suggest taking it to a reputable shop and have someone look at it for you. I understand DIY-ing these kinds of fixes can be frustrating - hopefully you get what help you need from a professional.
