GPS Receivers
with known Y2K and EOW problems are listed below
(14June1999)
The following GPS receivers reportedly will have EOW problems around
August 21, 1999. These problem will range from longer startup times
to failure to lock during week zero. The firmware should be upgraded
before August 21 1999. As far as is known, these units will report
the correct POSITION as soon as the units acquire lock.

Magellan is also testing products that are no longer in production,
with the most recently produced products tested first. The results of those
tests will be released as the individual tests are completed, and well
in advance of either the EOW or Y2K event. As of January 13, 1999, we have
determined the following Magellan products to be Y2K and EOW compliant:
FieldPRO V
Meridian
Trailblazer
Meridian XL
Trailblazer XL
NAV 1200
NAV 1200XL
SkyBlazer
SkyBlazer XL
SkyBlazer LT
SkyStar
Patriot

(Most consumer-grade units, including all Garmin, Lowrance and late
model Magellan
units, will sail through 1999 without a hitch.)

Additional technical notes:
1**)Motorola Traxar
Thank you for your interest in Motorola GPS.
Your Traxar unit should not encounter any problems with the week number
rollover or Y2K. As you are probably aware, it is not possible to
enter the year 99 when starting up your unit as it only allows up to 98
to be entered. Therefore, the way to handle this is to enter the
current date but for the year 98 when you power up. Allow the receiver
to track satellites and calculate the position, then allow enough time
for the unit to download the satellite almanac data (typically 13
minutes). Once you do this, the unit should be able to update its
position correctly the next time you power it up. If you haven't
turned on your Traxar yet this year, this is the process you will have
to follow to get it running correctly. You may have to do this again
after the week number rollover (August 21, 1999), and after the Y2K rollover.
We hope you find this information useful. Regards, Motorola
