I think a link to google maps will be the only solution that we can offer our customers. I'm not sure if they will like that it opens internally in Stanza?!
I hoped that there is a protocol like
navito://... or
nav://... that automatically opens the approbriate application.
Usually the webbrowser (safari, IE, firefox...) opens when you click on a link that starts with
http://...
It would have been nice if you click a link that starts with
navto://... and contains coordinates and automatically the navigation-software opens (navigon or TomTom or whatever) with the coordinates from the link.
We will try to implement the solution with the links to google maps coordinates.
Thanks for your help
