Navionics+ East

[stk44]

Hi all, 

 

I have a pending email to navionics, but thought I would ask here as well— 

 

if I buy a navionics+ card for the east region, can I get sonar charts for lakes that are not listed on the “lake list”? The reason I ask is first and foremost because I see lakes that have sonar chart data on the Free chart viewer (online) that are not on the “list”.

 

And secondly, would I be able to get sonar charts for Lake Erie with the east version?
