I am putting my 2 cents in for a future software upgrade upgrade to the TZT system. This machine needs a better steering page.How about the Data box information on a full screen...How about one large page showing a highway graphic along with Speed, TTG, Arrival, etc. My northstar 6000i had one page that filled the screen with just the highway mode. When returning from offshore I don't need to look at the chart. That was the page I always had up when running home. I was quite surprised that something so basic was left out.
