I have the 2.0 updates on my t12 and HDS 10-2. How to I check the Fishinchip. I just downloaded a lake on my new Nav+ card. It shows the area on the card when on line. I put in my unit and it will not read the card and the finshnchip view on my unit is dark and will not let you check it What did I do wrong. I went back to my card on line and tried to update the sonar. It said ups and error . try later. When I opened Navionics and went to up date/downloads and put my new card in my computer went wild with pop ups. Still does everytime I go back to it.
