I don't know if this will help you much, but I recently discovered an easy way to overlay ACA's GPS data onto Google map, using

http://www.gpsvisualizer.com/

Just download the pertinent ACA route gps file, extract the .gpx files, then plug into gpsvisualizer using upload, and voila, google-mapped route with ACA datapoints indicating route and points of interest. Other map formats are also selectable to which you can add .gpx data.

You can also import ACA data into a custom Google map using Google maps import feature. You must have a google account (free) and be logged in to create custom Google maps in this manner.

There's probably a dozen more ways to do this of which I am unaware.
