Unable to send speeds to PFD. Not in Sync error message

[Lauramks2]

Tried to send TO speeds and got a message that systems were not in sync. Thought about it for awhile and decided to see what that meant after TO. Turns out the Pilot and CP IRS systems were no longer tied together and that somehow blocks the speeds going to my PFD. Looked all around in the cockpit, manuals and online and never found any way to link them together.  One reference was to a menu in the IRS system but in my sim the only control there was to switch between Mag and True reference. Is this something that glitched on startup of the sim and not controlled in the 650?  I didn't want to restart so I flew with it and my only issue was I had to manually adjust the copilot system to get the charts I wanted on his MFD. 

Thoughts?

solved.  It turns out that I updated the database to IRS 1 but not to 2 or 3. When I updated them all, they synced up. That was interesting because I have updated a number of times before and only updated number 1. Maybe that was enhanced in a recent upgrade?

You probably switched database on FMS1 before the AC power was applied to the FMS2/3, by going out of order from the checklist.

Thanks, I probably did just that by jumping in the sim and getting my flight plan into the system trying to make sure my  filed flight plan in Pilotedge matched.  Thanks for the note. :-)
