just took delivery on my 945LTE. Garmin Express already shows a needed update for Maps...3+ hours for
TopoActive North America : 8.9gb
Coverage of Europe, Middle East & Africa: 15.1mb
Coverage of N and S America: 29.3mb
Coverage of Pacific: 13.4mb
are the latter 3 just some minimal map systems? (i'm in the US, so the large NA topo map makes sense)
