the reason i'm on old maps is because i sometimes use a full laptop for navigation for the bigger screen. SSD installed for the vibration. I've been using nroute to do this, as you probably know, it can navigate live through the map products once you connect a handheld gps to it. Anyways, nroute only works with bluecharts, topo, and city navigator NT's from 2009 or earlier. Out on the water, no big deal because i'm sure there's nothing new at the bottom of the ocean from the last 5 years, but in the marina or city streets, everything has changed. Topo is from 2008 so new dirt roads and city streets/poi's are missing. Unfortunately, nroute doesn't recognize anything newer when installed. All maps installed on the laptop show up in mapsource, but nroute will shorten the list to the old products it sees. ..and that's why i would like to see incremental updates to old Bluecharts. Unless i'm missing something, homeport and basecamp can not do this live navigation, right?
