Updating the headunit to the latest software should not cost you a cent , I have a copy of the latest update for RHP / REP units and I chexk and update any that come in for service , the update for the NAV section is minimal anyway there are no new map software updates to speak of for any of the Jeep Nav units , the new 2014s are all Garmin based but are basic and Garmin as far as I know dont supply chrysler with mapping updates like they do with stand alone dedicated NAV/ GPS units
