graggy, one of the changes to the software of the 898 unit over the years was to add the waypoint management system which got rid of the Export Nav Data menu. That function was moved and is the same as your 1199 unit now:
MENU>MENU>Nav menu tab>Waypoints, Routes, Tracks menu>Options>Select All and…>Export.
That should get the information onto the memory card which you can use in HumminbirdPC to see the waypoint data.
