Well, I was going from the statements made in the XOG users manual from the Lowrance website.
"NauticPath™ USA Marine Electronic Charts
NauticPath™ USA map cards show offshore/coastal navigational detail.
This plug and play map card provides electronic charts covering the
U.S. East and West coasts, Hawaii, Gulf coast, Great Lakes, Alaska,
the Bahamas, Puerto Rico and the U.S. Virgin Islands.
NauticPath features depth contours, intertidal zones and spot soundings,
navigational aids with view range and coverage. Extensive objectoriented
detail can be viewed, including list of lights, tides and currents,
wrecks and obstructions, marine services, restricted areas and
anchorage database information."
Granted, it does not exclude international charts (which I inferred.)
Navionics is not mentioned at all in the manual. It is, as has been posted, mentioned in the product specs.
Sorry for the mislead.
