The AVIC-X920BT is one of the best navigaion stereo units out there. I highly recommend it because it for several reasons. The navigation system was so helpful on a road trip I just took to Alabama and back to California. It helped me navigate without even thinking. The other part is the music system. I was able to use my iPod and play CD's. The iPod system was to die for. Of course the bluetooth was very handy. I truly understand now why it's called the starship. You will not be disappointed.
