Got a X after reading from second user. Wifi sync does not work

Same problem (second user do not sync and get the X when trying to sync after the reading), do not update to latest (1.07) version even after several attempts / days. After all this Garmin support requested to send the unit to them for service. This is in Nordics.    

We recently bought a BPM and returned it with a 1 star Amazon review due to this issue. You'd think Garmin would try to avoid things like that but here we are 16 days into this stupid issue.

Index BPM purchased 2 weeks ago, immediately detected another user sync problem. Contacted Garmin Czech, confirmed the problem, which they already know about and are solving it. After two weeks the problem is still not solved. A big shame on Garmin that they allow themselves to release a product that doesn't work as it should and even after 2 weeks they are unable to fix the situation.

Could you please post an update if you returned it to Garmin and did they "fix the issue" by updating to latest firmware?

For sure as soon. I have more information 

Same here in the UK, software version 1.06 and 9.32?

Just tried the delete, reset, remove battery door, reconnect and it's still software version 1.06

Rip, glad to know other folks are running into this, but it sucks that there isn't a workable solution as of yet :/

I have the same problem. I am also on version 1.06.
