I want to say thanks to Navionics customer service for going out of their way to help me get the updates for my Platinum card. I've been trying to update since purchasing it in June, nothing worked. The update down loads would fail on both computers, IE 11 and Google Chrome. I live in a rural area and my internet service is slow. In the end Navionics sent me links to the updates, instead of one large down load it was broken down into five smaller ones. Thanks Navionics for great service , I wish all companies worked this hard for their customers.
