Yup, all true.  The Y2K issue will affect the really old equipment, but
the GPS week rollover may affect any equipment.  Check out Garmin's Y2K
page at http://www.garmin.com/faqs/1.html

	Has anyone else heard of this problem?  The April/99 issue of
Soundings, a boating newspaper, indicates older units 'may' go haywire
on August 21, 1999.
	GPS satellites apparently broadcast time in GPS week numbers
which range from 0 to 1023.  The GPS week started January 6, 1980 and
will roll back to 0 on August 21.  Problems could range from date not
showing improperly, to searching for satellites where they were in 1980,
to displaying grossly erroneous information.
	Newer(?) models are supposed to handle the rollover.  They're
still testing to determine the impact on older models.
	The suggestion is to check out your manufacturer's web site or
call their technical support for current information.
	And yes, August 21 is on a weekend (Saturday).
