Rob, What are you trying to achieve?
As this may or may not help you. Whether they are bad radio’s or bad angle of screen or position of the radio. (I have no idea what engineer designed these, but I am 6’4”, I can not lean or look over in any safe position while driving) A lot of us have gone with external monitors. I only use the external monitor for backup and side camera’s (Mirrors are a better friend, but hey the cameras are there). I have a phone mount, for streaming music and backup GPS in line of sight. I also use a separate GPS, for the wifey (she's been telling me what to do for 34 years why stop
). I never felt the need to upgrade or change out my radio, as with my modification, it’s not needed.
Hope this helps.
