I have been researching car kits for my iPhone 4s since I need to be able to charge it and hear the directions when I am driving. I have the TomTom navigation App. The only two car kits that look decent are the Magellan and the TomTom kits. The Magellan looks decent, but most reviews I saw had issues with bluetooth or charging. Also, when using an auxiliary cable, the sound comes from the kit speakers AND your car speakers. Since I would listen to music most of the time, this is almost a deal breaker for me. The TomTom kit looks like it would be the better option. However, the only kits I can find are for the iPhone 3G/3GS. TomTom advertises iPhone 4 compatibility on their website, but looks like it needs an adapter. I cannot find a single website that sells the car kit and adapter. The few that are, have no stock left. TomTom's actual website does not even sell this. http://www.tomtom.com/en_gb/products/mobile-navigation/tomtom-car-kit-for-iPhone/. Does anyone know where I can find this kit that works with the iPhone 4s? If not this, does anyone have any recommendations for a GPS car kit? Looking for additional GPS receiver, speaker, and ability to charge. Compatibility with a case is not important. Searched forums and couldn't find anything.
