File Format
What file format works. I can record music however the file format does not work in my 2014 Chrysler 300 8.4N Radio.
Unfortunately, the USB device plugged into the radio must be formatted in FAT 32 and it will only play the following formats: MP3, WMA, or AAC. It will not play FLAC formats whatsoever. SDXC cards won't work either. I don't understand why Chrysler did not publish a list of acceptable playback formats in the manual. I think they assume that only Apple iPod and Apple iPhone users are tech savvy or something.
