Created by Griffin Technology, the iTrip is an innovative FM-transmitter that was initially developed for Apple gadgets such as the iPhone and iPod. It was the first device that made it possible for music from these MP3 players to be broadcast wirelessly on car stereos, and it is now the leading solution of its kind in the world. Over the years, new capabilities and features have been incorporated into the iTrip models, including Bluetooth connectivity and hands-free calling, to make it easier and safer for people to use their iPhones in their cars. There are iTrip devices that are specially made for certain iPhone models. If you are looking for an iTrip for iPhone 4 many options can be found on eBay.
