Does anyone have a clue of when the updated disc will appear for sale? I have checked the Pioneer site and talked to folks their and at Crutchfield and they have no idea. Thanks

Since the D3 is out and has newer maps, we are thinking you could use that to update the D1, but we are not sure.

It usually takes a couple months after the system is released before they sell the disks seperately. I would say you could probably get it sooner on ebay. People will often sell whatever disk they are not using (east vs. west.) And the D3 disks do work a D1 so I assume they will in a D2 as well
