Just continue to use MST&T 2013 for planning purposes. Shoot, I'm still using 2009 and will for years to come.
Then get something like a Garmin 50LM for about $100. Or go a bit money that will handle routes. The garmin has life time maps which you can upload at your convenience.
This is the combination I use. I figure out my trip and make notes on route points. Go ahead and find them in the Garmin which adds them to Recent Find so easy to locate on the road. Works for me since I don't usually have a particular route in mind, but travel according to what roads look like and signs that point to things interesting.
