MapSource + BaseCamp + Topo USA 2k8 + Topo Canada v4 + BlueChart Americas 2k8.5: Problem!

[solo_voyager]

I have BlueChart Americas 2k8.5, Topo USA 2k8 and Topo Canada v4 installed on my PC.
BCA is accessed through MapSource v6.13.7.
Topo Canada is accessed through BaseCamp v2.0.4.
Topo USA is accessed through both MapSource and BaseCamp.

I am planning a trip outside this summer.
I am trying to set up a route from a point in Alaska through Canada and the western states.
I have never tried to set up a route before with either of the Topo sets.
I am running into problems with auto routing in Topo USA.
I haven't tried it in Topo Canada because I haven't gotten that far yet.

--------------------------------------------------------------------
In Topo USA on BaseCamp, I have set way-points at:
Anchorage
Glennallen
Tok
Tetlin Junction
Hwys 5 & 9 Junction
Boundary

Then, I want to set up Auto Routing so that the route will follow the roads traveled.
I click on the route Options tab.
Auto-Routing is checked.
Vehicle type is Car/Motorcycle.
Calculation is for Shorter Distance
Road Selection is at the mid-point.

The route is still showing as a direct route from Way-point to Way-point.

-------------------------------------------------------
With Topo USA in MapSource, I can not use the Help file to find out how to set up Auto-Routing.
Apparently, the help files are for BaseCamp not MapSourcs and they do not apply.

Is it possible that having both MapSource and BaseCamp installed is interfering with setting up Auto-Routing?
How can I get Auto-Routing to work in Topo USA?
