The MapNav feature, for seasoned drivers, is good for those rare occasions where you do not know weather turning left or right will save you 50 feet. For everyone else it is quite useful. I wish ORION would have been scrapped and MapNav released by itself. The battery won't be an issue once everyone has the new cradles that continuously charge. We don't have them yet in my building but one of our drivers had his truck taken out to have work done on it and the replacement had one of those cradles. After finishing his route he had add/cuts to deliver in areas he is not familiar with and was only able to use MapNav, and the turn by turn directions, because of that continuous charging cradle.
