Folks,
Thanks for the input, that is some solid information. We have multiple Nuvi's and easily copy favorites, POI's, etc., between them. If the Mobile PC file structure is similar to them this would be easy. The hardware solution is something I will give serious consideration to. I will also look into Mapsource. When I have been to the Garmin site it wasn't entirely clear to me that Mapsource was something freely distributed to Garmin product owners, I assumed (perhaps incorrectly) you had to buy it. I also wasn't keen on having to learn yet another piece of software if my preferred option, multiple installs and navigation with only one, was available to me.
I appreciate the thoughtful input. I can't be the only person who thinks this way (no piracy intended, multiple installs, navigation with one) so if Garmin people read this site perhaps they can mull this over and put something clearer on their site indicating it is not only possible, but encouraged. A netbook with an 8.9" screen may be perfect for navigating, but for planning purposes something with a 17" or larger screen makes sense to me and probably to others as well.
Again, thanks for the replies and I'll keep fooling around with this stuff. The Copilot Live 11 software is buggy, does not follow normal Windows XP conventions in many ways, as far as I have been able to determine their product does not offer any ability to do as I laid out above, their support people are not responsive and they obviously work very hard to keep owners from doing multiple installations. Even some kind of licensing limit where you can only do two or three installs, like a Microsoft Office installation, would serve their purpose of inhibiting piracy, but it wouldn't be so burdensome on an individual owner. Having given up on them I am keenly interested in this Garmin product and will see if your suggestions help me to get to the solution I am shooting for.
Best Regards,
Phillip
