The UK has had the NavPlanner for months, Pat. :amgry
How it differs from the US software (Vaporware?) I know not. Originally it was to ship right after the Miami boat show, then it slipped to March 1. Maybe the software staff are all ex Microsoft employees....
I called the navionics office for the u.s. and as close as they could say was "spring" well spring has sprung and I can get it any where yet. They have to be mirco soft guys or steve jobs is in charge of marketing.
