I'm in the same boat. I have the HERE images working now, but Google Maps was WAY better. And the P4P+ controller doesn't have the same options as far as tuning the app. I guess we will have to wait and see what DJI does about it.
Check the threads, there's a new firmware out just today.Asked DJI about the maps in a chat yesterday which was completely useless. I did also ask when can we expect a new firmware release? Answer "unknown".
