[QUOTE=brianl;10460722]Lots to read here. I bought 2 elite 9TI,s that came with Navionics + cards from Basspro. The mapping is terrible compared to my old units and hummingbird. I selected Navionics and its not much better than the factory map? Could I be missing something or are these cards not very good? I tried to look at Navionics site but found it very confusing. It sucks being old with these new electronics! Thank you in advance for any advise[/QUOTEAs andre said, make sure you register and update your card with the latest maps.
Then when you put your card in the unit go to Charts, Menu, More Options and turn on the SonarChart layer.
