Hey guys

I am trying to do a bit of research for my non-technical savy friend. Basically he mentioned there is an update to panasonic cq-vd7003u dvd deck that gives it 3d map updates. I did a quick google search but came up with nothing. If there isnt 3d maps, is there some firmware update for it at all? I also went to the panasonic website, but could not find anything. Any help would be greatly appreciated!
