I bought a Navionics platinum chip today and downloaded the free PC app to view maps. Everything works just fine until i get to the "sign in" page where it asks for my email and password. Everytime i submit my email and password it says it cannot detect it. Is it really not free and they annoy you enough to buy the app? I dont see anywhere on the site to register your email or anything. I am beyond frustrated. I can see all the maps on my computer but it wont let me open them. This thing cost me $200 and so far i feel i wasted my money.

I have the free version that came with the chip also but had previously bought their premium PC app, about $100 at Navionics. It is light years beyond the freebie, which is of limited use in my opinion. Don't waste your time with the free version.

Ditto on both these posts. Had the same ro*** when I tried to download the free version...since bought the premium one and it far beyond the other.
