gen 3 mfd calibration

I've run into the same problem. I contacted my local dealer since the problem started appearing days after a check up/oil change/tire rotation, and I thought maybe they disconnected the battery and something didn't reset or get configured correctly when they reconnected. The dealer said that doesn't happen, and they didn't remove the battery for my service anyway. So, I'm willing to believe that my prius is just aging.

I researched this and found the same configuration/Easter egg you did. I don't find any calibration screen. I've tried all kinds on things... Nothing. This unit, the jbl e7022 is manufactured by Denso. I couldn't locate a manual online either.

One thought is that the screen may have a digitizer that doesn't require calibration... That the digitizer is just failing. After a few days of fiddling, my screen-touch alignment has gotten worse. I'm not sure how.

I really wish there was a solution to this, or a clearer idea of what's happened. Is it possible to replace the digitizer and/or screen? Is the whole unit going bad? What are the typical options? At this point, I'm sure I'm not spending a few $1000 to replace the unit.

One last note. The dealer said they'd check the navigation unit and try to fix it for $61. I have a feel that's a waste of time and $61 to hear them say the unit is shot... But I'm still contemplating.

One last item. I also have a 2010 Prius and my mac system has the GPS, 4-cd, satellite, Bluetooth touch screen unit.

 

Sorry to resurrect an old thread, but I too am having issues with my touch screen. On my Gen 3 Prius, my touch screen only works on the top half of the screen. I can get to the first hidden menu (just like OP), but can't figure out how to get to the 2nd hidden menu; Product Diagnosis menu.

Has anyone figured out how to do it? I have tried doing the 7 touch trick (i.e. top-left, bottom-left, top-left, bottom-left, top-left, bottom-left, bottom-right), and have tried holding INFO and turning my lights on and off multiple times to no avail. Instructions for these hidden menus on the Gen 2 don't work for the Gen 3 either.

I can tell from the Touch Switch menu that the top half of my screen is calibrated perfectly, but the bottom half of the screen shows all touches at the very very bottom. This means I can't use FM presets aside from the top 2 rows. I can't add new phones to the car for bluetooth music.

I won't consider replacing the digitizer or head unit, when I know a simple calibration is all it needs.

Thanks in advance for your help!!
