For my upcoming TransAmerica ride, www.work2ride.com, I just downloaded the ACA .gpx map files and loaded them into Google Earth and downloaded Garmin BaseCamp on my laptop. Then I also got the AAA maps for my trip from a friend for free and highlighted the route all the way.

I have noticed that some detailed roads are missing, but for those rare occasions I am planning to use my smartphone with GPS to get me through. I don’t want any electronics, including cycling computer, on my handlebars as I love them but don’t want my ride to be about them.
