The most IMPORTANT blue tooth feature IMHO, is the voice dialing. I have tried a Razor V3i and now a Motorola Q 9h Global. Voice dialing does NOT work on either. I feel the bluetooth module was wasted money.
BTW, Jetware says it's incompatible with the Q anyway...
I am less and less happy with the whole AVIC D3 system all the time. It may wind up on ebay soon...
-> Blue tooth usability is horrible. Without voice dial, either you continue to dial with the phone, or the use the screen interface. Either way, the blue tooth headset is a better option....
-> Ipod interface is seriously clumsy. Try finding something on a 60 gig Ipod. By the time you get done scrolling through the list, you are already at your destination... Very frustrating...
-> XM song /artist display is stupidly truncated, yet there is plenty of room on the display!!! What genius decided on that???
-> Why can't I have "Favorites" stored for XM stations, then scroll through them with the two buttons below the volume knob? This is just dumb. I need to drive, not fumble with the screen displays...
-> The GPS is horrible in my experience. I usally take my Garmin along because it works so much better and is easier to use.
