DP
I seem to have had a bit more joy with it, and had help from the developer in what I was doing incorrectly on the iPaq. Abandonded the idea of terrain data.
It needs a bit of polishing, but looks ok otherwise. I'll give it a bash (in my car, I need polishing too, in my DR nav so am not venturing onto GPS quite yet).
Cheaper (and from what I can tell, clearer) than the CAA official charts, but their accuracy is a little dubious too. I don't have a chart in front of me, but I'm sure the airspace around EGHI (on the east side) is missing/incorrect. (I think incorrect).
