According to reports in an Apple Discussions thread and in a separate but similar thread on the PriusChat forums, a number of iPhone and iPod touch users are suffering from in-car USB audio playback issues after the installation of iOS 4.1. Affected users report hearing “scratching” or “crackling” noises when playing back music from an iOS 4.1 device over a vehicle’s built-in USB interface, with one Ford Fusion owner likening the effect to listening to a “scratched CD.” The problem does not appear to be limited to any one brand or major manufacturer, and several users have noted that audio playback via the headphone port or Bluetooth works fine. Notably, one user claims that unpairing his Bluetooth connection allowed audio to play over USB without issue, suggesting the problem may be related to having Bluetooth on and or paired while attempting playback.

An interesting observation. After I powered off iPOD Touch, turned it back on, now the jitter problem seems to be gone again. No idea what is going on!  :(  Well, at least I have been able to enjoy music without crackling sound for past 30 min…

Well, I think I found the solution smile  After upgrading to iOS 4.2.1, if the problem comes back, just reboot the iPOD…  it has been 20 hours since my last rebooting, and everything is fine so far… smilesmile

This is weird. I never had this problem on iOS 4.1, but now that I updated to 4.1.2 it’s become a problem…

I have a 4 gig Ipod 2nd Gen. It will not work at all in my 2012 Toyota Camry, even though the manual says it should. When I plug it in via the USB port it doesn’t even register on the display.
