Hello everyone, I have a 2007 Lexus IS that is not a full option. I replaced the radio in a screen to become a full option. It worked fine for a long period of time, but then the problem occurred, which is that the screen becomes black in the morning and the buttons on the screen do not work so that I can turn on the air conditioner, but when the car is turned off for a while Certain and restarted it works and so then I went to an engineer and he told me that the problem is the motherboard, so we replaced it with a used motherboard and then the screen worked fine for 6 months and now the same problem but less and I expect that with time it will get worse Is the problem is the heat or my car does not respond to The screen is because it is not a full option, knowing that I put Bluetooth behind the screen. Is it the problem with the Bluetooth or is the Math Power broken again, I don’t know and I am very upset because I lost a lot of money and I did not find the solution to the problem.
Please guys help me😪
