Does anybody have experience with the Audiovox/Dice Electronics MediaBridge devices? I've got a 2006 IS 250 with Navi (no Levinson) and am trying to find a way to integrate my iPhone 5. This thing just has a USB port, so you supply your own cable and they advertise iPhone 5 and Siri support, just was hoping somebody can attest to how well it works and integrates with the factory stereo and controls.

edit: If anybody has suggestions for any other devices that'll let me charge my iphone 5 and play audio through the head unit, preferably using just the lightning cable, I'm curious to see how other people are doing this. The MediaBridge is available for about $200, so I'd like to keep it in that range.
