I know this may seem really elementary, but I can't get a confirmation on the official Tom Tom site. But if I buy the full USA map, do I get the same updates I would get if I bought a section of the US, say the US Southeastern Region, or US Midwest Region? Also, is there anyway to see if an area is on a map before I buy it? I bought my Tom Tom about a month ago, and the system says my map is three quarters old. I do a lot of traveling in both the New England and Mid Atlantic Region and The Southeast Region, so I want to make sure I would get updates for both those regions if I buy the full USA map.
