I plan to rip a bunch of my CDs and put them on a flash drive to play them in my Telluride EX. I'd appreciate recommendations for the type of flash drive I should get, USB 2.0, 3.0 or 3.1? Is there a capacity limit for flash drives for use in my Telluride, e.g. 128gb, 512gb or 1TB? Also, when ripping a CD, what format should I use; MP3, WAV or other? I tried MP3 with a quality setting of 320 kbps and it seemed to work fine even though my Telluride owners manual says "Sound quality is not guaranteed in case of music files that use the bit-rate exceeding 192 kbps". Has anyone had a problem using 320 kbps?
