Wow that’s a trip down memory lane. The old H2! 
I’ve hacked some BasicX code from the user examples on their site to read lat/long from my Garmin Legend rather than current date-time. (Can you believe that? Someone took the time to parse the nmea data stream get extract current date/time and set the clock on the processor?)
It works for lat/long and I intend to grab the speed and direction next. Then, my goal is to store waypoints in the processor and figure out which direction to turn to get to the next waypoint. I’m going to use it on a 4WD bot.
