I have received my (2nd) replacement Montana 700i. This time, the replacement was brand new with software 13.20.
However, after unsuccessful attempts to use the device with Garmin Basecamp (which only saw the device as a drive, ie not able to use the maps, Birdseye, transfer stuff etc) I followed Garmin Basecamp notification to upgrade the device with Web Updater. This resulted in a downgrade to software 10.50 (I didn't really pay attention then!).
Now, the device is stuck at 10.50 and Basecamp doesn't see it anymore, my MacBook Pro doesn't even see the device as a drive anymore. Garmin Express sees the device I think and is happy to say it's up to date with software 10.50, whilst before it was showing 13.20.
I'm confused. Nothing seems to work to re-update the device to 13.20.
Can anyone help?
