I have a Nav III with City Nav NT 8 preloaded and the disk and installed in Mapsource, etc. How do I load ver 8 onto my "old" City Nav II+ which still has City Nav 6 on it?
Do I just highlight the entire North America and Puerto Rico and transfer it to the Nav III using maps?
BTW, that doesn't work. The Mapsource won't bring up the Nav II if I try to do that. But I can bring up the Nav II as a device for other tasks. So this isn't a USB device issue, etc.
Anybody do this?
