NMEALog - A small, intelligent datalogger for NMEA-data
NMEALog is a small, intelligent logger that captures NMEA data for position and depth and stores it in a format suitable for amending existing charts.
NMEALog accepts data from up to two instruments natively, or several via a mux and logs data based on settable criteria, such as delta position, delta depth, delta time. Data is logged onto an SD-card and one card can hold several months worth of data.

Nice project. I have a garmin 64ST which can do NMEA output too, but I never managed to find the information to connect and test it. Would that be douable?
For example I have found this cable:

but i can't find the garmin information about how to connect it.

Why would you use current source for LCD backlight when you can use just one resistor? Its more simple and cheaper.
You have HD44780 display in library it makes a schematic much more readable.
Why is there no value on zenners?
