Similr to 2004. I haven't compared it to another product like duleo or destinator. But I like it, I got the plus version because it has phone number and address listings, like 31 million or something. Its convenient, this way all you need to know is the name of a place, get the address, then use the nav. to get there. The plus version costs 80 bucks. It now has automatic re-routing. I use it with my Lilliput fine. I imagine you already looked at http://www.delorme.com/streetatlasusa/ ?

Sorry I'm of no more help, searched and found no reviews
