Seems like it would be better to bring back Google Maps as the default map application and scrap Apple Maps. I've submitted errors and issues but they still remain after months. While they might have the resources, it seems like it would be better to use those resources on something else and just renegotiate a deal with Google for the maps application.
POI in Brazil were never updated. Every single blatant errors I saw were never fixed, no matter how many times I reported. They are just plain lazy. I would love to see, just the will, to fix anything from Apple.
