Hi Guys,
I just bought 220 last week. It synced to firmware 3.10. Now I have message on the web:
Software Update
Time Zone Map, Version 17.00
GPS Chipset Type M426 (Fitness Region File)
Forerunner 620/220, ANT
But when I sync nothing happens. I synced few times using usb cable but the message is still on the web. I pressed sync in garmin connect pc software and on the web. It doesn't look like I have any new firmware update on the watch and it did not 'spin' for update on the watch.
