I wanted to see what your thoughts are on the advantages to upgrading my NAV software version and DVD. My DVD disc is v2004-3. My NAV SW 4 -1/91.

Any worthwhile new features on either the sw or disc that would make me want to upgrade one or both? Do the graphics improve or simply POI's and map info?

FYI... the street I live on in Tampa, FL was built in 2001 and my nav version does not show it. I was wondering if the 2009.1 disc would have caught up by now and include, etc. as well.

Thanks!

Rob
