Apparently I have no clue what I'm doing. I downloaded the above mentioned file to an SD card, popped it in my F90BT, and started my truck. It didnt do anything, and browsing the "system settings" menu, I couldnt find anywhere that would allow me to upload anything from the SD card.
Any tips for a clueless newbie? I have zero experience with car audio, much less running programs/files/whatever on a headunit.
