I just rode for about 30 minutes in my neighborhood. I was passed by maybe four or five cars.
Somehow, I managed to create about 7GB of data on the 16GB card that Garmin supplied with the unit. Based on that, I couldn't ride much more than an hour without overwriting data on the card.
The 103UNSVD directory has 170 files GRMN0006 thru GRMN0092, both .GRV and .MP4 file types.
In the Varia App, there is a setting for video clip length, which I set to 5 minutes. However, I have 87 separate video files. indicating that I got one about every 25 seconds.
The User Manual is pretty silent on what I can do with this data, and how to do it.
I thought I might like to watch my ride, at least this first time. How can I do this?
