I was able to successfully image the drive this weekend. My next step is to copy a hard drive from a 2012, then load it in my car and see if it works. If it does, then I will know of an easy and free method to update the CIC maps.
btw, there is no OS on the drive. It just contains map data, gracenote, etc. The CIC will boot up and run just fine without the drive; obviously, navi won't work.
