G'day, Just after some info are feedback if others are having this issue, I have a early 09 build G6et. I have recently purchased an iphone 4 because as we all know, the FG series is designed to integrate seamlessly with apple. When I plug the phone in the phone displays the following "This accessory is not optimized for this iphone...You may experience noise caused by cellular interference and a decrease in cellular signal strength"" The phone still works through the ICC but I have noticed it often drops out or disconnects. I have liaised with the local dealer who have been as helpful as they can.. What we believe is the issue is that an 09 build date has a series "B" software package but for the iphone 4 to work properly it needs the newer series "C" software package. Problem is that the dealer can't find a way to update and I am having a real hard time believing that such a high end car would allow itself to be outdated so quickly. Does anyone know a solution?? Cheers, Mike
