Just thought about this: try calling the Humminbird Customer Resource folks at 1-800-633-1468 and find out the steps to reset the InterLink.
Was the InterLink connected to the 858 unit when you updated it?
I'll call Customer Resource later today. Yes, the Interlink was connected to the 858 when it was updated.
