I'm trying to install a comma 4 on a 2026 Honda pilot. The moment I plug in the USB c power cable from the harness to the comma ai device, I get lane assist not available and a bunch of other warnings. Comma doesn't power on too. If I unplug the USB c cable, all assistance features work fine with just the harness. Has anyone else faced this issue?

EDIT: Brilliant me used the wrong power port on the comma device. It powers on now but still getting warnings

EDIT 2: all working after correct power slot and a restart

I have not taken delivery of the car and neither have I sent in the initial down payment. I have signed all the papers. Is it possible to back out now?

Is it possible to back out of a new car deal if I have signed all the papers but not have taken the car delivery and made the first down payment?

My spouse was involved in a accident few weeks back. The police report says the truck driver who merged into her lane was at fault. Do I send a letter of spoliation to the trucking company or claims? Does that help with any misinterpretation of facts?

EDIT: I only have liability insurance

How would you describe the ride quality of the 2012 pathfinder? How's the NVH situation on highways and local roads?
