Para calcular a classificação geral de estrelas e a análise percentual por estrela, não usamos uma média simples. Em vez disso, nosso sistema considera coisas como se uma avaliação é recente e se o avaliador comprou o item na Amazon. Ele também analisa avaliações para verificar a confiabilidade.
Bought this to replace an old Garmin 12 hand held GPS, that was lost when I loaned it to someone. This unit seemed to be a similar product but with updated features. Well I really wish I could have just bought another GPS12 because this update is rubbish. The unit itself when it works, is so slow almost to the point of being useless, when finding some address or POI. Also the software is not very intuitive unlike the previous model, it takes ages trying to go into this menu and that to find the setting you are looking for. I connected this unit to my mac and eventually got it to synch all my waypoints and routes from another Garmin GPS unit I have and now it will not reconnect no matter what I do. The screen is to small to be useful for navigating as you really need to have some fields shown at the top such as distance to next turn and this then takes up so much real estate that the map picture is very hard to see. I also bought the UK road mas and the Marine maps and have been disappointed with these as well. I think i need to send my unit back as it randomly crashes and reboots or just stays off. When it works the software is poorly laid out and takes forever to do things that should be easy. All in all this was a very expensive package and no where near worth the money. If you want to have a car sat nav buy a Tom Tom, and for sailing navigation I certainly do not feel that I can trust this thing to work never mind aid my navigation so it is just as well it is waterproof and floats because I can see this thing getting hurled over the side some day soon.
