My navigation/radio/bluetooth touch screen has gone black. It will not light up at all. The button on either side of the screen do not work either. My manual AC and Radio controls still work but no display at all. I have had all fuses, battery and alternator checked. All voltages are fine. I repair center also disconnected the battery for about 30 mins to see if that would "reset" the screen. Still no luck.
Navigation screen goes blank. Misses turns or does'nt tell u to turn until it is too late to make turn. Has not been repaired.
I have a 2009 Lexus ES350 and on the naviagtion screen there is a Diagnosis check 1 displayed on the screen that will not go away. You are not able to control any navigation controls on the screen such as heat, map, bluetooth, and satelite radio.
