My mother's Model 3 has reported 30-40 sentry mode events every morning. She asked our local service center how to access those recordings. The representative told her to buy and return with a $60 64GB wireless USB drive, and now has cancelled four straight appointments to tell her what to actually do with it. (That's a separate annoyance. I have no idea why a wireless USB would be necessary.) I've Googled a bit, but it's hard to disentangle the threads about enabling Sentry Mode from the threads about actually recording/accessing the videos. I've inserted a FAT32-formatted USB drive into the USB slot, and from some of the threads I read it sounded like that would automatically put the videos on the device. So far though, nothing has appeared. What else do we need to do to save and view videos taken by Sentry Mode?
