I have a Hook-5 with a Insight Pro V16 CMap card in it. I can’t even find a person who can tell me if I have a Lake or Nautical card.
This unit was in a boat I bought in Michigan and I live in Wisconsin. I liked my HB with Lakemaster much better. All I had to do was go through the menu of lakes and click on it. I totally don’t understand what I have. Grrrrr!
