I've used a Garmin Edge 830 for several years now with very
few (if any) real problems, but the last couple of rides the
altimeter has gone crazy.  It takes the elevation for its
stored home location (692 ft) just fine when I start the ride,
but then it starts climbing on its own and then
descending--with no reflection of the real elevation.
 
Here's the profile that shows for the ride today (FWIW, I
never saw the unit display anything over the mid 900s)...

Anyone seen this before or have suggestions?  And no, I
haven't tried resetting the unit yet, but do plan to.

 
 The only time I’ve had some funky elevation is thunderstorms or
 rather a significant pressure change as front moves in.

Yeah, I've seen that behavior as well when there have been fronts
come through, but this is not in any way related to actual changes
in barometric pressure.

I reset the device last night (pain in the rear) and thought it
was okay--the reported elevation held pretty steady.  This morning
it did too with the unit just turned on, but when I had it start
recording the elevation started incorrectly increasing again.
