Re: BaseCamp version. If all you want to do is have an existing Garmin map management product installed so you can install a Mapsource "update", BaseCamp version is irrelevant. Install any version. Install the latest Mapsource update file. Uninstall BaseCamp.
BaseCamp has a number of features that Mapsource does not so you may want to have a look at it. The interface .. the entire paradigm .. is hugely different.
Re: Mapsource versions. 6.13.7 was the last version that did not support Garmin's new method of installing maps on the PC. It's also the last version with the old rendering engine. If you care about accurate representation of shapes of things (water bodies, islands, etc.) you will want to keep a copy of 6.13.7 on your PC. The new rendering engine in versions post-6.13.7 only renders things in proper proportion near Olathe, Kansas (the center of the universe as Garmin knows it).
Changes were made in very recent versions to allow you to manually change the centre of the universe so you can get stuff rendered in proper proportion "locally". It was a welcome bandaid but it's no real solution.
On a related note, nRoute only works with maps that Mapsource 6.13.7 can use. If you can't use a map product in 6.13.7, it won't work in nRoute. There is a reverse converter that will convert the new map storage format backwards so that it is usable by Mapsource 6.13.7 and nRoute.
If you plan to have 6.13.7 on your PC, here's the way to get there:
- install Basecamp
- Install Mapsource 6.13.7
- copy the Mapsource.exe file somewhere safe
- upgrade Mapsource to the latest version
- rename the 6.13.7 Mapsource.exe file to something else (I use mapsource6137.exe) and copy it back into the folder where Mapsource is installed (usually C:\GARMIN if you allowed the default).
- I have two desktop shortcuts, one for 6.13.7 and one for the latest version.
Going forward, you can just install new Mapsource upgrades as they become available. None of that will affect the 6.13.7 executable. It will run normally.
Some of us prefer the way the maps are rendered in 6.13.7 because it's more like paper maps and less cartoonish than the new method of rendering that everyone, not just Garmin, thinks is better. It's much finer detail. It's also a lot faster redrawing as you pan and zoom ... LOTS faster.
If the National Geographic maps do not advertise themselves as being Garmin-compatible you can be pretty sure they aren't. That doesn't mean you shouldn't get them if they have information you want. Just don't expect to use them in a Garmin nav device or program.
If you want free USA topos to play with in Mapsource and Basecamp, you can download Dale's Ibycus USA Topo map. It's made from the same data that is used to print the government 1:50,000 topo maps. You can use Mapsource to load them into Mobile PC. (I've never tried loading maps with Basecamp so I don't know if it supports Mobile PC.)

You could do all of this to amuse yourself and stay out of our hair while you wait for your Mobile PC to show up.
