Well I figured it out without using GPS Babel and without deleting the routes off the handheld and then re-downloading them.
I used the files I already had downloaded to Humminbird PC and then copied and pasted just the waypoits into a new file and then onto the SD card and into the 788c. It worked pretty slick doing it that way and saved a bunch of extra work. I do however see the need for a program like GPS Babel, because I am not able to do the same for the track info.
Thanks to those who replied and I hope this helps someone else with the same problem I had.
