there was a general 'roll-over' for GPS receivers just after Y2K that
required sofware / e-prom, etc. changes to keep them 100% compatible
with the international system. You should ckeck to see if this was
done (or not) on this unit. If not then the unit would not be totally
realiable with the worldwide system upgrade.

=====================================

That's true but for me the real issue would be lack of WAAS
capability. WAAS has increased average accuracy of GPS positions from
+/- 100 yards down to about 15 yards. That is a REALLY significant
improvement, and is now frequently more accurate than the charts. If
you doubt the significance, take a look at the number of channels and
inlets that are less than 200 yards wide, or take a close look at your
visible range in heavy fog or rain.
