My suggestion would be to have a look at OziCE....but there is a fair bit to it if you haven't played with it before & ozice is not free but does have a demo mode.
These are the limitations of the Evaluation version.
Moving map mode (communication with the GPS) will only remain active for 20 mins each time OziExplorerCE is run and then 10 mins after that (until restarted). At the end of these times a dialog will be displayed and communication will be deactivated.
A watermark using the text "Demo Version" will be drawn onto the map.
Other than for the restrictions mentioned above, the evaluation version works exactly the same as the purchased version.
Its a raster mapping program rather than a routing program like IGO8. So basically you supply a series of pictures as calibrated maps & it plots you location on those maps.
By default OziCE comes with a world map - which has very little detail but it will show you where you are.
You can load your own more detailed maps (pictures such as jpgs & tiffs) once they have been calibrated & converted to the format required by ozice - there is a free tool to do that on the ozi site, but the calibration required the windows version of oziexplorer.
