T-SB-0013-11
Says there is a new audio ECU for people who have a 5th gen T4R and an iPod product that has issues with the head unit.* It specifically says that you have to have an iPod that falls under the list to get the TSB done. There is also a VIN limit. Something in the 25000 range, IIRC. They must have made a running change sometime with the redesigned ECU that works with most of the modern iPod models.
* My 3rd gen iPod nano works with my T4R but my wife's 4th gen iPod nano will occasionally give an "error 3" code. I'd only be eligible for the TSB under my wife's iPod.
