Further to my earlier post - my son uses the <Nav4all> sat nav on his mobile phone. The program itself is free and they also have a tracking program for your pc - so you can see where you are even if the phone is next to you :-)
Although he has a GPRS phone, he actually uses an independent Bluetooth aerial/receiver unit with it. He failed to answer the obvious question of how the position signal actually ends up on the pc so I guess you'll have to find that bit out for yourselves if you are interested :-( Trevor [Non-text portions of this message have been removed]
