I have the nav. system installed and was looking around in the settings menu to change the color and full/split screen. In my changing to see the difference some thing changed that now changed the 'Settings' main menu option to 'Set'. I can not figure out how to get it back to say the word settings like it use to. Also, now I notice that at each corner of the screen there are corner markers that did not previously appear. Has anyone seen the porblem before and can tell me how to get back to normal settings.
