Here is the one I have.... http://www.ebay.com/itm/Bluetooth-Au...item19d2faf676
$12 shipped. I am using Torque pro( the paid version) and would highly recommend over the free. Sorry iphoners, only Droid does. The mountable video RCA was obtained at radio shack for $2, and the micro usb to RCA was like $5, if you use the HTC one that I have it will charge your phone while plugged in. That's it, I already had most the stuff so this mod cost me $2.
