Hi there,
You can download the data required from
http://www.pocketgpsworld.com/ however there is much more to it than that. You need to copy the files from the Nav Pro disk and edit many of them - then save the new files to a DVD-r. It is quite complicated. Alternatively you may be able to download a modified disk if you know where to look. If you do you need to be sure you are downloading a Nav Pro disk as opposed to the Nv Business - they use different disks.
