i was driving home one afternoon when for no reason i looked at my navi screen and it twitched from normal to this...

i didnt know what happened and so i tried to fix it by pushing back into the dash... i popped it back up and it was still like that.. so i left it alone.. then outta no where, it fixed itself.. WEIRD!! then a 2 days later 2 mornings in a row, when i started up my car and my the navi was doing it again, the screen was yellow! WTF!! it fixed itself again. it then happened again later on that night but this time i shut my car off and started it back up and it was fixed.. honestly this is starting to **** me off.. any ideas on what could be the problem could be? i want to bring it to the dealership but theres no way they can "comfirm the complaint" because it happens randomly.. all i got are these pictures..
