Well, simple solution is to replace the screen itself.
No amount of calibration can fix a broken screen. Sometimes they just brake or been punched. Who knows.

I have no idea how much a replacement screen goes for but all you need is part numbers from the radio and hopefully your google-fu is strong with you.

If it was me I would just dump any and all oem units and go for any aftermarket unit. For $300 you can have all the bells and whistles with backup camera option, apple car play/android. Etc...
