Garmin Forerunner 310XT Firmware Update 4.20

Garmin just released its latest firmware update for the Forerunner 310XT. As stated on the website, the main and only change from 3.90 to 4.20 is to resolve the GPS acquisition issue. I'm having this issue in fact, which I later on sort of "resolved" by resorting to always clearing the GPS cache.

I did so by pressing the ON button and the DOWN button simultaneously. While it takes a longer time to obtain a fix, but once locked on, the GPS accuracy is usually around the range of 8-9m. This is compared to 12-14m by just powering on the unit.

I'm still waiting for more feedbacks from our brave early adopters of the new firmware before attempting to update, but the initial results seem promising. Itchy fingers...
