Just like it says in the title. I have not pulled the car battery or anything, and the constant power definitely didn't switch off because everything else remains intact.
If I go to the menu where I can choose my backgrounds, it will still say that the CD is chosen, but it would show the default wallpaper. Re-uploading the pictures fixes the issue but this is going to be an annoyance if it's going to keep happening. This is the second time within a month.
Does anyone know what is going on?
