I didn't say $350 to change a battery and, since the full text from the
website was posted by Brian, I won't repeat that.
My 302 is suffering from multiple problems, namely, the on/off switch is
faulty, I'm getting the wrong date in log files, and it's completely
losing GPS lock resulting in multiple log files being generated on a
single flight. So I think the price is probably reasonable considering
the cost of a replacement.

I just talked with Gary about sending in my 302 which is exhibiting 3
separate issues. He quoted me from their webpage that they have moved
to a fixed price schedule for repairs. $350 should repair all faults. I
think that's a lot less expensive than redoing my panel with newer
technology and, besides, I really like my 302.

Cambridge 302 and GPS-NAV owners – IMPORTANT NEWS
Unfortunately, there has been a rash of Cambridge Model 10/20/25 and
302/302A with a fault in which the units lose track of the date and do
not record a flight log, or record a flight log with an incorrect date.
The problem is related to the internal Garmin GPS engine’s UTC date.
This is a new issue, but there have already been many reported instances
– especially from areas in which there are soaring flights this time of
year. It is very likely that many 302 and GPS-NAV owners that have
their gliders put away for the winter will, unfortunately, have the same
issue during their first flight in the spring.
If you have the optional LCD display connected to your 302 or GPS-NAV
flight recorder, you may be able to tell whether or not your unit is
affected. Connect the GPS-NAV Model 20/25 to a GPS-NAV LCD Navigation
Display, or connect the 302 to a 303 LCD Navigation display and give the
unit time to lock onto satellites before continuing. The GPS-NAV’s LED
will blink when it is locked onto satellites. The 302 will show 3 bars
on the right side of the screen when it has a good lock on satellites.
Then scroll to the UTC date/time screen. If your unit is working
properly you will see the current date. If your units is not working
properly you will find an erroneous date – such as 2005. In that case,
the unit will need repair.
If your GPS-NAV or 302 does not have the optional LCD Navigation
display, then the best way to determine whether your units is affected
is to take a flight (or drive) and look at the date of the flight log
that is generated. Make sure the unit has a good lock on satellites
before takeoff. If the flight log’s date is off, or no flight log is
generated, then the unit will need repair.
The bad news is that the units will need to be sent in for repair. It
is not possible to repair the unit in the field. This issue affects the
GPS engine which is inside the logger, not the external GPS antenna.
The great news is that Gary Kammerer at ClearNav can fix them. The
Garmin receiver has a 3v rechargeable battery under its cover. The issue
is not related to the 3v logger security button battery. Gary can remove
the Garmin’s cover, replace the 3v rechargeable battery that is soldered
to the Garmin circuit board put the unit back together and then send a
couple of commands to the GPS which wake the Garmin back to reality. The
new battery keeps it working properly after the repair procedure.
Without the replacement battery the Garmin's memory cannot be kept
"alive". Gary has performed this fix to dozens of 302 and GPS-NAV units
he has received from all over. They have all been successfully repaired.
