Does anyone know of any car chargers with auxillary out that work with the iPhone 3g? I know I could just connect to the headphone port, but I've found that audio quality is better from the dock connector, and this way I have less wires to plug into my iPhone when I get into the car. The only one I know of is the LiquidAUX, but that is expensive and I really don't need the remote. All I want is a car charger with the audio output to plug into my car's stereo.
