Unfortunately my car does not have an iPod kit or Aux in, so I've been using FM transmitters. I've had some by Belkin and Griffin and they would always end up breaking, even with just normal use (plugging iPhone in/out). So, I took the plunge and ordered this kit and it actually looks promising. It sends music wirelessly via bluetooth from the iPhone/iPad/whatever to the dongle plugged into the cigarette lighter and then sends it via FM or AUX in to your car's audio system. Everything is controlled via a free App by NewPotato and you even have the ability to sync multiple devices, which is pretty cool. Here is some information: http://newpotatotech.com/TUNELINK_AUTO/tunelink_auto.html YouTube Video: http://www.youtube.com/watch?v=iO_vviNvTJQ Hopefully it will arrive by this weekend and I'll post a review in a reply. Has anyone tried this product out yet?
