My gps measure in kilometers and is set fuse hour +2. if you need miles must change data model from neogps library. hour is just gps time +2 is not a fuse conversion, check on Sd card your time hour and add your right number.
last version SH1106 write 11 data on SD card and 8 data on display.
one of these days i will make a ready to use miles version.
in schematics draw you see a buzzer used for a speed limit, autovelox etc. I have change it with a led light as to show when fix is ready.
just add a new feature sketch with more data. add satellites count, max altitude and aerial distance from fix point. useful to find the way back by decreasing data numbers or understand the max distance point during a walk from a start fix base camp.
please let me know your suggestions and if you find errors.
