The device has internal storage of some capacity (I am not certain what it is), and it has two micro SD slots. I spoke with customer service and my understanding is that user profile data is stored on the internal drive. It was not clear to me from my conversation with customer service where the driving data is stored. I removed both micro SD cards and the driving data is still on the device but the video recordings are not available without an SD card inserted, so the driving data is stored in some capacity on the internal storage. My question is how much driving data is stored on the internal drive? At some point in time, that storage capacity will be exceeded.

I would like to have all historical driving data available to me for review. Is that goal possible? If the driving data is restricted to the internal drive, at what point will that data be overwritten? Does the driving data ever get stored on the micro SD cards?

Customer service rep advised me to purchase two 512 GB micro SD cards so that “I don’t have to worry about it”. Is that the plan?

In summary....
1. where is the driver profile stored?
2. is the driving data stored on the internal drive and is it possible to run out of capacity for driving data storage?
3. are the micro SD cards only used for video storage, or is the driving data also stored on the micro SD cards? ]]> Data Acquisition and Analysis for Racing and DE mdirads https://rennlist.com/forums/data-acquisition-and-analysis-for-racing-and-de/1509633-garmin-catalyst.html
