Im working on an open source nav hardware solution that provides instruments as well as charts via your web browser. Works on anything with a web browser including iPad via a private wifi on the boat. I have an early demo up at Freeboard [MeshCMS]
Comments welcome.
iNavX and associated charts can control your boatsautopilot. Navionics app can't, but if using primarily as a good planner and back up, both are good. Navionics, on an around the world trip would work out cheaper.
Put Navionics HD on my Ipad 2 yesterday and wow! It is full screen, touch screen with every thing else you can think of. On of the best 34.99 i have spent. Only thing I have to figure out is how to mount it at the helm. Any ideas?
Have a look at 'gumdrop marine series'. They have a number of support brackets available also.
