Where do I go to download it?

Either use the Garmin Webupdater as Scotty suggested (recomended), or download the file directly from here: http://www.garmin.com/software/Edge605_705_320.gcd

rename Edge605_705_320.gcd as gupdate.gcd

copy it on [X]:\ (main directory of your 705) overwriting the existing one

bring the 705 outside with a good satellite view

Switch it on, and wait for update to complete and aquire a satellite fix.

Despite the elevation crazyness I had on 3.10, I downgraded to 3.10. I had one successful ride on 3.20, Saturday had a ride not even recorded. Weird grade and elevation is better than no data to look back on.


Garmin forums are also so full of complaints about this FW level that I don't know how they could release it. There's even one post dedicated to one guy "bragging" about successful rides he's had on this level.


Crazy... this is not how it should be.
