Sorry for the confusion... the name of the gauge is: NavTestGauge (note 
case sensitivity). The current incarnation of this gauge only loads 
airports and some classes of VOR's, and is best used in latitudes below 
60 degrees n/s because of the Mercator projection. I'm working on a new 
map projection system but it's not finished yet.

Boeing737NAV used a bunch of code that was incomplete (the original 
developers disappeared) so I should remove any references to it from 
the .ini file.

It should point to the .dat files - I should clarify this in the 
documentation.

If there is no nav data to read, I believe this results in OpenGC 
aborting (I haven't tried that error case in a while). If it does not 
receive a network comm from flightgear or another sim, the gauge will 
display but remain static.

Hope this helps, any other questions please let me know.
