GPS II+ failing to acquire.
|

| My old II+ was used recently on a trip and failed to acquire within 20 minutes.
The satellite page showed a good number of birds with very good signal levels,
but it clearly had trouble computing a solution. Eventually it worked it out,
but 20 mins cold start is a concern. Previous use was two weeks earlier, seemed
OK then. Batteries were good.
Back home I set it up on the bench. Again several sats in view, signal levels
were about one bar. After a time, the (expected) "select init method" screen
was presented. I selected "keep looking". Two hours passed without a fix.
Powered off and on. "Select init method" came up again, I selected country
list. An hour later, still no fix. Power cycled and it came up with a fix
within a minute.
Any idea why it is so inconsistent?

| Since its a 2+, sounds like the backup battery is exhausted. I also have a
2+ and it acts in a similar fashion. The battery is only good for 5 years.

Maybe. On internal batteries on the bench, it often gets a fix now, but having
ahd a fix for say 8 hours it suddenly shows an altitude of ~ -1200m or +7800m
and gives a message "power down and re-init". On so doing, it reacquires but
some hours later repeats the wacky_altitude_power
_off_and_reinit behaviour.
