For a long time,  I've used an iPod Classic modded with SD cards for 512 gb of memory.  Recently with my other car,  I discovered iPod Classics are no longer supported,  and since neither is iTunes, I thought about modernizing.  I used Media Monkey to build a library on a 512 gb flash drive. It works in that car. Decided to do the same for my vehicle that has the AVIC7200NEX. I've now tried loading the library 5 times,  but every time it freezes at 60% formatted and i can't select songs or artists when that happens. The drive is a 512 formatted in NTFS. Has anyone gotten a flash drive to work? I've reset the unit twice trying to get it to rebuild,  but always it freezes at 60%

I believe that both my usb and sd card are formatted in FAT32. My usb is only 128gb, can’t remember the size of the sd card. Both work fine.
