405CX won't sync

Former Member over 14 years ago

I have never had a problem with auto-sync with computer until now. No matter what I do, my 405cx is not being automatically picked up by Garmin Connect to download my latest history. Is there a way to force it to sync. Force Sync is turned on on unit, but how do I force it to sync?

This has just started happening to me too, reboots of the watch, my laptop, unplugging and replugging the ANT+ stick, nothing works.

How should I go about debugging and fixing this?

405X can't connect to Garmin Connect

January 1st 2011 I made a sync - since then I haven't been able to sync either. Garmin Connect is asking me to up upgrade from 2.1 to 2.3, but I can't do this since the watch will not connect.

What's happening Garmin? :confused:
