2014 Corolla stereo screen gone white.

Helping a buddy with his stereo issue.
2014 Carolla with premium stereo. Screen has gone white and stereo does nuthin. Is this common and if so what is the fix ?
Have been googling the crap outta it but no solid answers.

Some Entune premium units seem prone to freezing. Some never find a solution, some do by updating the map SDcard with a new one an others by doing what's in that video. Good luck !
