Regarding USB drives cutting off the ends of songs, 2013 Dodge Dart Aero with 8.4 Uconnect: 1) Shut off Gracenote. This helped a little. 2) Updated stereo firmware. This helped not at all. 3) Took out USB drive, ran disk-repair software, eliminated "Mac specific" files (there weren't many), and removed 2 GB of music from a 32 GB thumb drive. This works around 80% of the time. I suspect I need to clear off more music. Anyone else have similar experiences?
