I had the same thing happen over the weekend. Drove out 2.5ish hours and back in the same day, different leaving and returning routes. Both times is shut off about 1.5h into the drive (with 95% on-interstate) for no reason and required hard reset.
Agree with the other folks that have it installed - took longer to take my stuff out of the tunnel!
Pretty great looking piece of kit, and definitely looking forward to adding some sort of basket to it.
Works fine for me, but I have seen this happen before.
It’s been as simple a fix as quitting maps and Rivian apps and reopening them. Give that a shot!
I’d love to see what you’re doing with the switch panel. I keep seeing all these silly installations with a freaking key fob remote for each light, which (for me) doesn’t track nicely with such an expensive truck!
edit: JK, I scrolled to the next post in the list and found it! Looks great!
