Again, thanks for all the info. I got a cable and connected the 1198 and the 998 and had a great time looking at that setup. I did see what you said about the waypoints. Figured if I needed them on each unit for future reference or whatever, I would transfer them via SD card. Didn't see any other quirks, but I'm not totally set up yet. I've ordered some stuff and will work on it this weekend.. I'll post my progress.
Thx
