yes you can override the system, goto the volume screen, use your finger and tap on the upper left hand side of the screen, just above the strip of adjustment numbers and than tap just below the strip of numbers, do this several time back and forth...once the screen changes you'll see a series of buttons you can push, push and hold the "override" button for several seconds. your NAV system has now been overriden and can be used while moving. hope this heps. please be careful while driving
