Transferring maps from GPS to computer

What did the message say? I would like to know how to do this too??

Hi - the Nuvi comes with City Nav maps preinstalled. The question was can these be downloaded from the NUVI to PC and viewed with Mapsource. Answer is no as far as I know (though there is probably an illegal "hack" out there). Obviously if you had the CD version of City Nav loaded on your PC it could be viewed with mapsource/nroute but this is not the case in this instance.

Cheers
Greg

I use Mapsource all the time, you can move the mouse pointer around until you get the exact Long Lat them select the google map view to make sure you've got the right spot, make a way point and then send it to your GPS. Its fantastic if you've only got the Lat Long positions.
