I have a 2009 335i sedan with a July 2009 build date. The car was ordered with the iPhone / iPod adapter option and "Y" cable from the factory. It charges my iPhone 3G with no problems, however my wife has an iPhone 3Gs and it will not charge her phone. It will play music and all other functions work but no charging. The phone comes up with a message that the phone is not compatable with the device for charging. I have heard that other BMW owners have experienced the same problem. Was wondering if any club members have experienced the same problem. Again the car will charge the 1st generation iPhone as well as the iPhone 3G just not the iPhone 3Gs, by using the factory supploed "Y" cable that plugs into the center console. Will likely contact BMW and see if there is a service bulletin on this issue or some type of solution.
