New iPhone-compatible FM transmitters, chargers, and Bluetooth accessories are finally starting to arrive, so iLounge has assembled a Guide to help you make the most of your iPhone’s calling and music features in any car. Today, the major problem is that there’s no single accessory that charges, mounts, and performs all audio from an iPhone, so unless you want to hand-hold your iPhone while you drive — which is against the law in many places — you can’t just connect one cable and expect to safely use both its music and phone features. So for now, in-car use of an iPhone requires a number of different parts, and the “Complete Guide to iPhone Car Integration” helps you choose the ones that are best for your vehicle and personal needs.
