Outdated does not mean not true. When a User or buyer of anything learns some material facts that is negative about any product, and decide to move on, it is not normal the User's or Buyer's responsibility to continue to view that product as viable. If I go to a restaurant and food or service is bad, I leave. Not only do I not go back, but if one ask, I will tell them my truthful experience. A few years ago the RV GPS App was about as bad as it could get, I faithfully tried. I am 100% sure there are threads on the issues and to my knowledge, no one spoke of an update or new changes.
I have two systems now, maybe I can try for 3. My biggest knock on the RV GPS App now, is that I simply don't need it. It would have to be compatible as an app on my Android Auto device. Until then Waze wins, during the interim if I ever do run across a low bridge and I am somehow distracted to not see, I have my Garmin RV890. I would not recommend anyone to buy the RV890, I just have it because I have it.
