If I try to use any of my RT tunes it says code 20004 or something like that and says invalid SD card.

I trying in plugging everything and I also took the card, put it in my compute and uploaded all of the files onto a new micro SD card and put it back in and it read the same thing.

My actual horsepower tunes still work but my RT tunes can't function without the SD card.
