As a former experienced IT professional and now aerospace engineer, my opinion is that the software and firmware on this and the last two garmin products I've purchased, they units are extremely buggy and un-satisfactory for a high end tech product.

Beautiful and strong design but unfortunately a very weak software

In truth, my main gripe with the device is actually the software, which I find to lag far behind the competitors in this arena (e.g., Runkeeper, Nike, etc.)

Read several reviews, Most stating that the software is buggy however the Last two models the Watch would reboot, flicker and go into a Boot loop without any display shortly after die even when charged

Beautiful and strong design but unfortunately a very weak software

It is now showing "unsupported software".

It is PAINSTAKINGLY SLOW; seriusly Garmin, this is the 21st century, put a better processor in your huge watch or write better software for your watch

The Fenix 2 software seems a fragile

Some of this can be avoided now that Garmin connects to Nike, but it would take a significant software upgrade for me to give this device 5 stars.

As the watch has had more and more exposure to the market, Garmin has made some significant software improvements to the watch

Unfortunately, the software is horrible.

The majority of problems that people report are from the old firmware.*The Garmin Express software is not perfect either

n’t work

And random problems abound as
