which is the best Navtech dvd for me?

[carlos3679]

Hey all
I have a good technical question,
I live in manhattan and am looking to upgrade my Navtech DVD, when looking at www.navtech.com here are the descriptions I get for the DVDs.

Map 5: Midwest and Ohio Valley - Release 2005.2
Update Maps for: BMW / X5 / 2001

Description
This Map CD includes the entire states of Indiana, Kentucky, Ohio, West Virginia and parts of Illinois, Maryland, Michigan, New York, Pennsylvania, Tennessee and Wisconsin.

Map 6: New England and Mid-Atlantic - Rel. 2005.2
Update Maps for: BMW / X5 / 2001

Description
This Map CD includes the entire states of Connecticut, Delaware, Maine, Massachusetts, New Hampshire, New Jersey, Rhode Island, Vermont, Virginia, Washington D.C. and parts of Maryland, New York, North Carolina and Pennsylvania.

I am inclined to think that it's map 6 but would like to know if there are any New York City owners here w/ nav, which map are you using? does anyone know the difference in what New York areas are covered by what DVD?

thanks in advance.
