Slightly OT but there does not seem to be a VIRB hardware specific forum...
Appears something might have been amiss with firmware v2.70 from yesterday.
Garmin has now replaced it with v2.80 - but release notes are unchanged.

Change History
Changes made from version 2.50 to 2.80:
* Improved software reliability
* Improved photo capture performance
* Fixed intermittent issue with entering mass storage
* Elite Only: Improved ANT sensor stability
* Elite Only: Fixed issue with Daylight Savings Time
Needs WebUpdater to install (invoked automagically from VIRB Edit!)
Installed - seems okay. More testing later.
