After doing the factory reset this morning, the broken dashcam and trips display are working. Aside from redoing touch screen option selections, I had to recreate driver profiles, name the car again, redo Homelink setup, reset FM radio stations. All of that took maybe a half hour. All my Slacker streaming favorites carried over, which was nice.
What I have not done is recreate navigation favorites and browser favorites. I seem to recall that setting up the links to Teslawaze and Tesla Winds and Elevation will require getting tokens again. So I've put that off.
Overall, no regrets doing the factory reset.
