Now that is useful - thanks for sharing your work.

I live in a rural area and sometimes need to record and share a remote location; some months ago I was trying to advise the police of the location of a stolen car - OS co-ordinates are the best media for this.

Now all I need is something like ViewRanger or similar to display OS maps on the N900 (wth or without GPS)

Any ideas?

I'll give you some feedback in a week or so, and thanks once again.
