Gray Tone

This screen checks problems with contrast. You should be able to see the changes from bar to bar across the scale. It is normal for the two bars on either side to appear the same. If you cannot see changes from bar to bar, replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION  ).
