Last night stereo was fine with 100% function. Started today, Toyota logo was slow to appear. Next it froze on that image. Restarted car twice with same result. Drive a few miles and I got a black and blue split screen with an blue Image of the head unit and a progress bar (like when you are downloading something) . Progress bar seems wto suggest something is loading. Gets 15% across screen and then it resets. Tried to disconnect battery but no luck. Turn car off and back on and progress bar makes it 80% across. No sound and no button control. If I hold down volume knob the unit does reset but no change.
