PDR SD card?
What is everyome using for the PDR SD card? Is there a specific one that is required or recommended? I plan on running it all the time essentially like a dash cam. Thanks for any info. I appreciate it.

Get a high endurance card, like those intendd for dashcams and security cameras. The minimum class is in the owner's manual but just about any modern quality will exceed it. Exceeding the class requirement only helps when downloading information from the card onto a computer. And be aware that there a lot counterfeit cards out there.

It might. I haven't tried one in my car, in original format or reformatted.
There is usable disk space on the card besides the encryption stuff, so it may work right out of the box.
Try it, and let me know?
I'm using (I think) a Samsung high capacity class 10 card I got on Amazon.

I use a SanDisk 512GB Extreme PRO.
Had a bit of a problem first using it. Put it in straight from the package without formatting it. The car saw it and I tried to format it from the car. It disappeared right after that. Couldn't see it again. Took it out and formatted it on my laptop in exFAT format. Still didn't show up. Decided to give up for the night and left the SD card still plugged into the car.
The next morning, I tried it again and it showed up. Not sure if it was a 2026 bug. Letting the car sit overnight reset something and it worked afterwards.

From Google AI, paraphrased:
Counterfeit flash drives and SD cards are highly prevalent on Amazon, with estimates suggesting could be ~50% of listings in high-value categories, including memory products, could be counterfeit.
- How to Avoid: Purchase only from "Sold by Amazon, Shipped by Amazon.com" or verified official brand stores.

I doubt GM put or chose state of the art processor/RAM/ROM in the PDR system.
The 2024 OM says " exFat formatted, class 10 SD card, minimum size 16GB" on page 131.
Your card is half a terabyte.
