Yes, I found that out too by placing an original locked CN SAF 2017.30 NT map file in one of my other nuvi's in combination with an appropriate .unl file. I saw the same copyright remarks. When I returned to the forum to share this information, I see you came to the same conclusion. Amazing how the device had the car rental POI's and that totally by chance of all maps exactly this very one has an AvisBudget copyright remark, putting me on a ghost hunt!
