Here's how I did it. Format using exFAT and adjust the Allocation unit size. Try 256 Kilobytes and see if that works. That's what I did and it worked perfect.
Do you have a link to the card?
Those are the cards I use for all my dash cams. It'll work out of the box in the PDR, but not the SVR. I tried to use the PDR to format the card, and it still didn't work in the SVR. I then formatted Fat32 from my Chromebook, and it still didn't work. I then formatted exFat from my Chromebook, and that worked. However, some are saying it should be Fat32 formatted, so maybe I am misremembering.
I may have to use one of the 3rd party tools on my Windows PC....as long as it works for SVR after reformatting.
Yeah looks like the 32GB micro SDs work out if the box with SVR
32GB or smaller probably work out of the box because 32GB is the max efficiency size for FAT32. In reality FAT32 can go beyond that, but FAT32 is begins to become inefficient once you get beyond 32GB. basically its becomes slower to read/write than other file formats. However for a video recorder that should never be an issue. So it is possible format FAT32 beyond 32GB, but you will probably need a 3rd party program to do it. So most 32GB and smaller cards probably come preformatted in FAT32. Anything beyond 32GB would be exFAT if its preformatted.
For those of you who might read the manual and be lost, the slot is just to the left of the steering wheel. The white does clash but I think I will skip the magic marker! 
Did exactly this and it worked fine as well. Also agree on the SVR interface. It's really un-intuitive and feels like something out of windows 95. As of now have no idea if its constantly recording when the cars on or not.
