The date on my Garmin 12 GPS version 4.59 has reset itself to 12 -sep -
1987. I cannot find a fix on the Garmin user support site. I see that
someone had a fix for this last year on this list. Can someone help me
out? Thanks!

I have the fix, can i send it to your email ?
It is a small program.

Iseem to have the same problem. Hasn't used my garmin 12 for some
years. Now it works OK but gives me a date of 13 january 26. Would your
fix work for me too? I would be very obliged if you could mail it to
me.


Have you tried resetting the Garmin 12 to it's original factory defaults
to see if this solves the problem?

You'll lose all tracks, waypoints, user datum, user grid etc. ...
According to Garmin: 'Contrary to what some people have heard, Garmin
guarantees that a master reset on the GPS 12 will NOT mess up any type
of temperature compensation of the clock or anything that will change
the accuracy of the GPS at all. It will only wipe out user settings and
clear the almanac.'

You hold down the Mark key and turn on the unit and then:

'When the warning for way point erase comes up at the buttom, move the
cursor to NO, back to YES, back to NO, back to YES again and then press
ENTER. You will see "Acquiring EPE" at the top and a message screen will
flash indicating you to press the "Page" key. Leave the unit with good
sky exposure for 20 or so minutes until you have full 3d lock again.'


All the above is courtesy of Prof. Y.Lupardi of the Netherlands. You
might want to check out his webpage for the other undocumented features
of the Garmin 12 as well:

There's also been a software update for the GPS 12. So, if your's is
older than 3 years:

Lots of luck.
