I've been reading through the Display Audio w/ Nav manual and I must say it sounds impressive. Those with iPhone/iPods will love the simple, built in plug and play connectivity, on screen control, and voice command. You can even "tag" a song on the radio and when you plug in your iPod the tagged song data will be downloaded and next time you're on iTunes it will give you the change to buy the tagged song. The Navigation system features seem pretty nice too. More intuitive to operate and search nearby POI's than in the past. Most all the weird quirkiness of the Gen2 system (which I despise) seems to have been eliminated. Features include Traffic, Turns indicators, Lane guidance and Sign posts. All good Except for Toyota insistence to not give us full functionality while moving. Just let me sign a waiver, jeeez. The voice command system seems much improved also. Commands can be given without having to be in a particular screen. No more redundant questions/confirmations. Just say what you want in somewhat of a full sentence and it does it all, instead of piece by piece commands. I think, but am not sure, you may be able to speak POI "brand" (Wal-mart, McDondalds, etc) to the Nav system. Display Audio appears to eventually be what the standard audio/info system in all Toyotas The Premium Audio system is even better.
