    IMG_1788.jpeg My ‘05 drives fine but the screen only shows this. Any ideas?

    It's just a boot screen so maybe the screen itself or it's electronic board been replaced maybe an Asian market car etc . Who cares boot screen . All else functions normally . Nope don't know how to change

    Someone was able to access the system and replace the boot screen image... This is how people first learned to hack Hondas at the start of the 2000's. Toyota has thus far been locked down too much to do what Honda hackers can do, but this photo gives me hope.

    Or maybe its just the wrong ECU? @SFO or @ChapmanF what ECU controls this screen? Does a Lexus have the same plugs?

    This is also a relatively common early failure mode. Upon boot up after turning on the car, it will sometimes show the Toyota boot screen and sometimes Lexus. The MFD is heading south and will likely fail soon. If that screen is all it shows, the mfd is done and will need to be replaced.

    Who changed it prior to your ownership?
