Kensington LiquidAUX: Bluetooth Version (Bluetooth music streaming?)

[MBHockey]

Hey all,

I'm having some trouble determining if the Kensington Bluetooth Car Kit uses bluetooth to stream music from the iPhone to the charger. When I say charger in this post, i mean the Kensington piece that plugs directly into the cigarette lighter outlet.

I have an aux-in port in my car stereo, and I love having my iPhone 3G hardwired. Currently, it sits in a ProClip swivel mount with a standard 3.5 mm audio cable running from the iPhone's headphone jack and into the aux-in on my stereo...but it's a problem for me when I have to pick up the phone since I have to disconnect the 3.5 mm audio cable and then hit the screen to answer the call (when my music is playing). The handset mic is disabled when the 3.5 mm cord is in the headphone jack (presumably because the iPhone then thinks you have your Apple-supplied earbuds connected which has its own built-in mic) so hands free calling is not possible with my current setup.

So, the Kensington product seems to be a good solution. But I do not want it if the music from my iPhone is first sent via Bluetooth to the Kensington charger and then sent from the 3.5 mm audio cable from the charger to my aux-in port because then it isn't hardwired anymore.

I cannot discern if this is the way the product works, or if it works by just sending the iPhone's music audio out on the standard USB charger cord (that you must supply; it does not come with one) so that it is wired directly into the charger. I really want it to work this way and be a fully hardwired solution.

There's a few things I don't understand here:

1. Does the regular USB dock connector cord allow audio to be sent over it? I'm not sure if this is even possible, or if you might need a different "special" dock connector cord which allows audio to be sent over it.

2. Can the iPhone even send audio via Bluetooth in stereo? If it can't, i guess this would be a definitive answer that the Kensington product must not work via Bluetooth streaming (from iPhone to cigarette charger)...right?

3. And lastly -- the most confusing fact -- Kensington does not supply the USB charger cord with this makes me think it must be able to still work with your iPhone's music without this cord. This would mean it'd HAVE to be sent via Bluetooth from the phone to the charger, and then out the auxiliary cord.

If anyone can help me untangle this web of massive confusion I've weaved myself into over the past two days while trying to find a good charger/aux out all in one unit, it'd be greatly appreciated.
