The bluetooth module is DEFINITELY worth it. It's not perfect. I have a Treo 650 and I still cant get the names from my contact list to show up on the avic on an incoming (or even outgoing) call comes in. No big deal..I usually recognize the actual number showing up on the avic, or worse case..I pick up the Treo from the cupholder and see whose calling. Also..I HATED Ipods before I got the Avic. Overpriced, can get more space/features for 1/2 price with a Creative Labs Nomad. BUT..the ability to load up the Ipod, stick it away in the locked glovebox, and control it from the Avic? Priceless. And with a video Ipod (which I have), I load the Ipod up with music videos from LimeWire and presto...music videos on the Avic AND on my headrest monitors. Try THAT with a Zune. :lol:
