Best GPS software to use with our new feature?

[mstevens]

I've got a great SERO plan for data, but it doesn't include the ridiculous $10/month for navigation. I've also got very good built-in nav systems in my cars (which also use inertial navigation, wheel sensors, and other goodies for keeping track even with no satellite lock) so I really don't want to spend ANY extra. The only thing I'm ever likely to use GPS on my Mogul for is for Windows Live searches, tagging photos with coordinates, and wandering on foot in unfamiliar cities. Maybe on the motorcycle if I can get voice guidance over Bluetooth and some sort of helmet bluetooth solution, but

I think that means that, for my purposes, Google Maps is it for the moment based simply on cost.
