I have a gps mouse connected and this (free for 28 days) gps program works very well & I am quite impressed with it!
you can download it here www.yahnav.nl
if you click on 'international' in the top right corner in the opening screen the programme switches to the English language.

Hopefully the free chart range will be extended later to cover the North Sea and the east coast of England, but at the moment it of more use to our Members in the Netherlands (& possibly America as well?)
Please post any comments or thoughts you may have over this navigation program,
Have fun.
