I have a HB 859 on the bow and HB899 on the console that are linked together. I am needing to enter a bunch of waypoints manually while I am at home. If I enter them into one of the units will they show on the other and do I have to have both units on while I enter the waypoints on one unit for them to show up on both?

Also, it seems that if I don't have both units on while I am fishing and hit "mark" on the unit that is on, the waypoint that I "mark" will have a numbered big blue dot on the screen. Then when I turn on the other unit it will show a small blue dot for that way point and it will not show a number for that small blue dot. Is that the way it is supposed to work?

Thanks for any responses.
