"Almost there, just FM-sender missing"4.0 starson by frankhansen99
Pros: Combines microphone and loudspeaker amplifier, in addition to reference-standard GPS-receptrion. All this through a industry-standard bluetooth connection compatible with most software. In addition aux aut will let you connect to a modern car-stereo.
Cons: Pricey, and an FM sender would make this product perfect
Summary: I've not found any car holder that has all these functions. In almost every area the iPhone has meager car-performance, this holder compensates. Sound is amplified throgh the microphone, audio out is clear and loud, and GPS is much more accurate. The holder itself is very practical and easy to use. It will hold an iPhonoe with protective cover as well. I've connected the holder to a FM sender (IceMan iPhone holder) thorugh the aux out, the only thing I do every morning before driving to work is mount the iPhone: the bluetooth connection doesn't initiate until the phone is mounted.
