Hi All,

1)
yes, we probably have a fix for the GPS25 modules, but it has to be
confirmed working under all circumstances by a GPS simulator. This will
of course take some time ...

2)
We do NOT have the sourcecode ...

3)
The only two solutions Garmin has officially suggested to us a

a) recharge the battery for 2 days and reinitialize the module by it's
serial interface to a new date = obviously this only works for another
2-5 months.

Also, the rechargeable batteries inside the GPS25 also age with time -
Garmin should know this. We got lots of new modules at beginning of the
2000s which were not able to hold their time and date for even 2 weeks.


Yes, isn't it strange that when the problem first blew up in 1999, no one
suggested that merely replacing the battery was an adequate solution?
Yet now some people are claiming this is a "fix". It's a temporary Band-
Aid (rtm) that can fall off at any time. Probably when you're least
expecting it.


b) replace module by GPS15 module.

For technical reasons, both solutions are not an option for us, thus
we'll continue work on the firmware-patch, and at the same time on a
software-only solution (new VALI-GCS files, maybe new VL firmware).


Ian seems to be using the GPS15. As you no doubt are aware, it requires
a physical adapter, has an even tinier battery, and is no longer in
production. New firmware for the GPS25, or the VL, seems to be the right
solution. Glad you're pursuing the issue so vigorously. Perhaps Garmin
could be coerced into doing new firmware if the proper level of
complaints were directed their way. They released new firmware for GPS15
in 2009, but I can't find any info on whether it would have the same
issue pop up in 2019, or some other date.



Good luck with the CAI solution.

Tnx, but I don't suffer from delusions that the 302 is some kind of great
navigational device like some people do. When mine dies, I'll just
replace the logging function with something better.
