Wow this is quite a nice suprise. Nicolas gave in and released the source of AndNav2. So I can now spend my time hacking that instead of reverse-engineering it 🙂 I rooted my HTC Hero so I actually don’t need to do that anymore, but that is really beside the point. With the source available there is no ends to what can be done 🙂
As I have said before, I really think this is a killer app for Android. Google released their navigation which is nice, but I’m not sure how well it works in offline mode.
