Hi! I sold my eTrex 20 and bought an eTrex 30.
1) My first observation is a strange behaviour: on this eTrex 30 the firmware update process (the update itself, after the „validation”) is MUCH-MUCH LONGER then on my former eTrex 20. Is 4 minutes 10 seconds, while on the eTrex 20 was 1 minute - 1 minute 30 seconds.
2) An other experience: With the same firmware versions (2.80 and 2.90) this eTrex 30 has much more malfunctions than on my former eTrex 20. Crashes, freezings during route-navigations; capricious unexpected shutdowns. It's hard to believe that the extra functions of the eTrex 30 (altimeter, electronic compass, sensors, wireless) make it more unstable.
-> It's a defective sample or the eTrex 30 is more problematic generally?
