I just completed a chat session with Chris at Garmin. Looks like they are working on a fix for this issue, and understand what causes it. Here's a transcript of the chat:

Chris : Here is the latest information from the Garmin engineers on the issue, which they are still looking into:
Chris : We found that having Auto Start off can cause this issue, our engineering team is currently working on a fix. In the meantime we recommend having Auto Start on.

On your Montana:

Go to the Main Menu (home icon)
Tap on Setup
Tap on Routing
Tap Auto Start to turn On

RH: Excellent info, that matches what I have found. The act of saving an activity while activity recording auto start is off apparently overwrites the operating system in the area of the expedition mode, triggering the fault. I can work with this resolution, and would definitely want to know when a permanent fix is available!

Chris : you will be sent an email once the issue is resolved.

RH: Very good, thanks for the update!

Chris : Thanks for choosing Garmin. Have a great day!
