Are you using Navigraph Charts? It has the flight plan route, live aircraft location and an optional satellite imagery. If you dont use it, it is highly recommended regardless of the satellite imagery.
Also, a short google search brought me this free app:

Simbrief can also export the flight plan to an XML file (see "flight plan downloads"), you can try and do a research weather it is possible to use it with Google Maps.
