I'm sure this has been asked and answered but I can't find the answer here. I searched for a good USB for dash cam and Sentry according to recommendations on this forum. I don't need it for music. I ended up purchasing a 64 GB thumbdrive https://www.amazon.com/Transcend-JetFlash-Flash-Drive-TS64GJF710S/dp/B00LFVIUGY and formatted it according to instructions on this forum. I did not have the option for FAT rather only exFAT. According to Google, " exFAT is a modern replacement for FAT32—and more devices and operating systems support it than NTFS—but it’s not nearly as widespread as FAT32.." Once formatted (not using the fast format option), I added the TeslaCam folder and plugged it into my car. Nothing appeared on the screen. Does anyone have any insigt or suggestions?
