Greets:

Downloaded the chart and updates from NOAA service 
http://www.nauticalcharts.noaa.gov/index.html

uncompressed chart and ran it in qgis. Whats interesting is that qgis reports 
"Warning: No valid projection. Unable to set map units." and in fact while the 
chart renders, I cannot do anything with it. Very strange.

Ran the conversion script to completion as well as gdalslice script and all 
works as it should

Starting gpsdrive and navigating to the selected coverage area gpsdrive nag 
screen pops up with cannot load chart and -d error output reads 

loadmap(top_noaa_11466_1_4800_3072.png
POPUP: Warning
map zoomed!
***no valid Position:

So not really sure what going on here but both qgis and gpdrive report similar 
errors.
