Yup, fat32. I am using a 64GB card in mine, and had to find a utility to format it to fat32. I have about 36 gb on it currently, and like troutspinner it takes about a minute to first loadFat 32. I don't know that there is a limit on size. Do beware, the more songs you have, the longer it will take to load when starting up. I use a 32gb, roughly 2,600 songs (320 cause I'm a bit queen) and it takes 45 - 60 seconds or so.
I am using mp3, various bit rates because I have not taken the time to rip my whole collection of CDs the right way... I still have some that I ripped at 96kbs 13 years ago when hard drive space cost much more than now. I currently rip 320kbs vbr and the uconnect radio plays them all fine.what format/bitrate files are you using? mp3? aiff?
