I already own it and have it installed. The HD radio works great (I recommend that you live in an area that has stations that support it) The transition from analog to Digital is seamless and is a big bonus when a station has sub stations that have no commercial (SWEET!) The Built-in blue tooth has work flawlessly (with my Blackjack II), But the biggest asset to me is the source level input, this function allows you to adjust all of your devices/sources to play back at the same or whatever level you like (no need to turn up the radio after playing the CD or Masstorage MP3).
