@RamIt, My OEM SD card went bad. I'm not trying to just randomly replace or upgrade it. In fact, I haven't even updated my firmware in the two years that I've had my truck tuned. Hell, when I got the code that it couldn't read the SD card, I had forgotten where the little thing even was on the unit. I got a 32gb card because that was the smallest available at the time; not because I wanted or needed that size, only choice was 32gb, 64gb or beyond. As storage goes, 8gb storage is ancient and 2gb (OEM size) is near impossible to find.
I appreciate your help, and the tip about parallels is good to know. My wife runs that on her macbook. I may give that a try.
But to be clear, I didn't just start f'g w/this out of curiosity or because I wanted an SD w/bigger storage. My truck runs great and this is mostly just a nuisance.
