As always, he provides an awesome review of the changes. He also noted what he knows about the plans for rolling out to other devices like the Edge 500 and FR 310XT
As previously announced by Garmin back in September, the goal with respect to adding all the new fields was to get the Edge 800 firmware done first, then follow up these same changes to the Edge 500 and finally, the Garmin FR310XT. The Garmin FR910XT will come with these features out of the box. The goal at that time was to have the units following pretty closely after one another for the firmware updates – meaning on the order of weeks, not months.
