Does this also function as a speakerphone? I'd like something that can function as both. If all I wanted was audio I'd just use the headphone jack but I'd love something that
1. Is wireless, so I don't have to plug anything in every time I get in the car.
2. Functions as a speakerphone, meaning built in mic and call audio routed to car speakers (output from the device could go to my aux jack)
3. Streams stereo audio so I can play my music
I can accomplish all of this easily by rigging up a wired connection but I'd love to not have to plug anything in. Currently I use a computer headset adapter for cell phones. Basically it's made for people who like their computer headsets and want to use them for their phones. It plugs into the headset jack, and has a mic input jack and an audio out jack. I plug a microphone which I have mounted in my car into the mic input on the cable, and I send the audio through my stereo aux input. It works fine, but I hate wires.
