Help! Humminbird track import

Help! I need to import a track to some newer HB units asap. I have a sd card that I successfully transferred a .ht file in the Matrix folder. 997, 998 etc work fine but when I t r y with a newer unit it doesn’t transfer. With the older units I just need to power up with the card inserted. On the new unit it seems that you need to insert the card when powered. But the track doesn’t show up…thanks in advance

What are the newer unit model(s)?

I believe it was the 1159CI HD COMBO. There were a couple other smaller ones too but I noticed that the Waypoint screen/menu was completely different.

Not an issue anymore because the time has passed but I would like to know for future reference.

Here is the link to my IDO topic on this subject.
