Yes (unlike AndNav2), AndNav1 does not provide realtime-routeguidance!

The Android/Google Maps Terms of Service disallow any realtime routeguidance based on a sensor. Which is what a navigation-application is in the common sense does. The reason for that are the various data-providers (liek NAVTEQ, Teleatlas, NASA, etc...) that earn a lot of money, by selling licenses of their data to navigation-system manufacturers like TomTom, Garmin and all the others. Google didn't buy such a license from every provider and so we cannot implement such a system, even tough it is possible!
