PDA is on the cards and I will look into WAP. The question is would you be prepared to pay for the service?
I am looking at producing a datafile suitable for Navigator software by Memory Map. See www.memory-map.co.uk
to download 10 day free trial software. Its a great piece of kit that allows you do do all your passage planning on the PC on digital charts, and then upload the waypoints and routes onto your GPS.
I would be interested in comments on this or any other navigation software that people have used.
