Garmin Forerunner 305 Training Center & GPS Unit Updates, PDF Manual (Edge 305, 705, Forerunner 405)

roadskater's picture

A recent discussion of calorie counting on the Garmin Forerunner 305 here...

...mentions updates to the firmware in the GPS unit. For convenience, here's a link to a page about the software (or firmware) updates available...

I gave the WebUpdater program a try and it worked out to be an easy way to update the firmware in the GPS.

My Forerunner 305, purchased over the 2007 holiday period, had version 2.7 "software," and it updated to 2.8 with no problems. The "GPS Chipset software" after the upgrade was 3.0 (I didn't notice what it had been before).

I don't think any of the updates will affect my Forerunner's calorie measurements. Perhaps this is not the update spoken of in the article, but I think it more likely that the original article was simply too optimistic about there being an update that would greatly improve the calorie estimates. I like so many other things about the Forerunner that I'm OK about the calories, but it is disappointing if they got this as wrong as it seems. Also, it'd be nice to have barometric readings, and for cyclists, the Edge 705 looks like it has just about everything, including a color screen, barometric altimeter, plus cadence and power readings.

I hope to have a comparison of the Polar 720i (700 and 800 series) barometric altimeter readings with the Forerunner 305 readings soon. I grabbed the data the other day at Country Park.

The manuals are up as PDF files too, by the way. Check it out if you'd like to see what the unit can do...

Here's a link to look at a comparison of the 305 and new 405 when it's available (looks like I like the 305 better overall despite/because of its size; the 405 loses some features and adds others)...

For educational reference purposes, I quote the update history of the previous and current updates of the unit software for the Forerunner 305 so far...
