Prototype navigator app for Android

Hello, I need navigator app prototype for trucks. Features: - three route propositions (like in Google Maps) - voice navigation in English - streets list for route (like in Google) - overview of the upcoming manoeuvre and distance shown on the screen - free offline maps installed on device or SD card - points of interest for trucks (truck parkings, motels) - speed limit and camera warnings (like in MapFactor Navigator) - 3 display modes (whole route, fragment, 3d when driving - like in MapFactor Navigator) - day/night map mode - maps rotating in driving direction, or north up - vehicle customisation (weight, height) I need the source code with comments also, because I'd like to customize the code further myself. Which APIs and libraries do you plan to use? Thanks for bidding.
