I have the same issue too but it's for my wife's 2012 Subaru XV. We didn't get a SD card with the car when we bought it so when I recently disconnected the battery to charge it, the next time I turned the accessories on I saw the message "program loading is necessary please insert SD card." The dealer wants $500+ for a new SD card, which if it comes to that, I'll just install a new head unit.
Its a slightly different model than the one mentioned above but hopefully the operating software is similar.
If anyone could send me the files that would be much appreciated. My email address is: firstname.lastname@example.org
