I have been working on adding new waypoints on my PC with Humminbird PC Program and when I insert the card with all my new points the 898 it displays loading but the only points i Have are the ones that were already there. I have 71 waypoints on my card ( the ones I uploaded from the unit and then added more) but I see I only have 47 the same number I had before adding the new ones. I looked on the manual and seems I am doing right but I know I am missing something. any advise
thanks eric
