Car kits for iPods and iPhones aren't exactly big news, with plenty of third-party accessory companies feeding off the ecosystem already. But an Apple-branded kit, found buried in iPhone OS 4?
The "iPod Out" feature was found mentioned in the iPhone OS 4 code, alongside "IAPSSimpleRemoteCarButtonNotification", "IAPSSimpleRemoteCarButtonTypeKey" and "kCTCallStatusChangeNotification". Rumours about an Apple car have been bandied about the last few years, but perhaps an Apple-branded car kit, which docks the iPod or iPhone, charging and streaming, would be something they consider pursuing. It could even allow the iPhone to be used as a satnav, either docking horizontally or perhaps feeding a larger display.
