So I purchased an SanDisk High Endurance 128 microSD card with a SanDisk adapter to replace my Tesla thumb drive in my MY. I did some research and saw that I have format the sd card. I have a Mac and formatted it as a MS-DOS (FAT), selecting the "Master Boot Record" option. I didn't want to partition because this SD card will only be used for sentry/dashcam, so I don't need to have music in it. So I placed the SD card in my car and at first it didn't recognize it. So I formatted it again but this time using the Tesla operating system. It worked for a little bit, the camera icon showed up on my screen and then a few minutes later disappeared. Does that mean my car is not recognizing the sd card? Why? Did I do something wrong? Miss a step? Thanks for the help!
