Maps

I want maps on my device when I'm out and about (and without needing a live internet connection to download).

On my windows mobile device I used to use GPSTuner (until I got fed up with the pricing /licensing model ) and then I wrote my own mapviewer programmer for the windows mobile platform.  So I have quite a lot of maps in GPSTuner format (which uses map tiles) and PC tools (of my own making) for downloading, calibrating and managing them.

I have been using OruxMaps on the Android, and it works well.  I would recommend it.  Plus points include free, good tools for downloading maps on the PC (And on Android device) from a variety of sources and good support response from the developer.  However, it doesn't handle tiled maps and it looks as though converting my existing set of maps to use with OruxMaps isn't going to work.

So, I'm thinking about taking my windows mobile code and writing something similar on the Android.
