google maps navigation

Question

Hello!

I want to develop an gps application that can navigate to some predermined locations in a database.

I have created a mapview wich is working just fine, I also have a MyLocationOverlay to show my position and I have a ItemzedOverlay to show the locations to which I want to navigate. This is no problem. the problem is the creation of a route from the phones location to a predermined location.

If anyone knows anything I will be happy for your answers!
