Hi, I have a Zander GP 941, one of the few in the US. It's recording

"Where a FR has already lost the date facility, the solution is to
return
the FR for modification to the manufacturer or his agent. The fault is
because the GPS receiver no longer registers the correct GPS date
Epoch, reverting to dates in 1 the first Epoch which started on 6
January 1980 when the US GPS system first went on line after its
development phase.
A GPS date Epoch consists of 1024 weeks (19 years and 36 weeks)
before the next Epoch starts. Where this fault exists the date
recorded is typically 1024 weeks too early, and in some FRs other
faults may also be present. We are now in the second GPS date Epoch.
This started in August 1999 and will change to the third Epoch in
April 2019. If the GPS receiver or FR firmware recognizes that it is
in the second date Epoch, the correct date will appear on the IGC
file."
Has anyone else been able to overcome this by simply charging the unit
or does the battery have to be replaced. if so who can do it since
Zander has shut down. I love this recorder and the Zander ZS1.
Someone should create a next gen with nice big moving map display.

Have you tried cantacting Franz Pöschl at

The same thing is happening it model20/25s as well as volkslogger schism
is a bug in the Garmin gps25 embedded in these devices. Probably your
best bet would be to invest in a nano or similar.

More charging won't fix the units, even a new battery wouldn't be
adequate since the units think they're in the previous epoch and need to
be reset.
The gps25 just wasn't adequately engineered to have such a long lifetime,
and the FR vendors could have done a better job of supporting the thing
in the application.
I always wince when people spend as much fixing up the old units as a new
unit with far superior specs would cost. Time to move on.
