Thanks vinced. I think what I will do is get the DVD and keep the microSD card as well. Best of both worlds.
I tried the TracBack method before my post and was very frustrated with the results. Maybe I was not doing something correctly.
In the meantime, I have found a nifty website (ridewithgps.com)
http://ridewithgps.com/ that actually allows the creation of routes if you start from scratch. You then export this file as a gpx route and do a GPSbabel conversion to a gdb file.
If you then open the gdb file with MapSource, it appears as a fully functional route with all of the turns information on it. This sounds far more complicated than it really is.
To my knowledge, ridewithgps is the only mapping website that has this feature. All of the others leave you with standard track files. Unfortunately, this site has awful editing capabilities, so it is really only good if you want to create a route from scratch. It is a work in progress, and the creators of the website are committed to improvements, unfortunately its more of a labor of love, than a paying job. Lots of potential.
Ultimately, the simplest, most straightforward solution is the DVD. What really bothers me about the DVD is not the cost, but the fact that it can only be used with one device. I understand why they have to do it like that, but it really ticks me off.
