Not sure about posting this... but here goes (answer to thread title at end): I mostly listen to music off my USB stick(s) and have done so since I got the car. I have noticed some flacky behaviour which was very sporatic in nature. About 3 weeks ago I had a much more significant incident -- it started with the music skipping with the song, then skipping between songs. Moving to Internet audio didn't fix the issue and moving back to USB audio led to the screen becoming much less responsive (presses taking a long time to react, if they did). Talking with service, I was instructed to reboot the center screen (which did clear this all up) and call back when it happened again. A couple of days ago it happened again - but it cleared itself up after about 30 minutes. I reported the incident to the Service center and went on with my day. This morning I got into my car to find a "Service Needed" red banner across the top and my car no where near charged. Called up Emergency service who had me reboot the center screen. This did clear up the message, however, we were concerned that the car had STOPPED chargering! Ok, called up normal service to see what they may have found... Service believes the usb stick was the cause of all the issues, including stopping the car from charging. USB is something I got from Best Buy and formated using Windows XP. Service asked me to pull USB stick from car and see if the problem comes back, and if not to try a new USB drive. Thoughts?
