If this has already been addressed in another thread, please point me to it. My issue is that Tesla Support had me reboot the car using the two steering wheel buttons then had me do a power off. This brought up the dash cam icon and I was able to format my SD 128g high speed which worked for a little while then turned off. I cannot get it to come back up. I have tried rebooting and power off several times, nothing. So, I have a formatted disk but does not matter if it is plugged in or not, dash cam icon does not appear next to sentry mode icon. Suggestions?
