They would be the same as the 1197 units we built in 2009 plus the software differences (once they are released) like Down Imaging, SwitchFire, Waypoint Management, LakeMaster mapping card capabilities and the ContourXD maps. No electrical component or PCB changes are going to be made. Basically it’s the same unit with the new software additions.
