If I understand this correctly, it can...but may have to be ordered the way you want it to begin with??
Background Map - Expanded U.S. BaseMap or Lake Insight™ or Nautic Insight™ (Americas) or Worldwide background map (non-Americas)
For the Americas, you get a choice of incredible, built-in Lowrance Insight cartography with your model selection: Lake Insight™ for U.S. inland and Great Lakes; and Nautic Insight™ coverage for detailed U.S. coastal waters coverage.
I am not convinced that the Insight mapped HDS's are worth the additional cost. I would be using my Navionics mapping card anyway. Having said that, I could be convinced otherwise. As of now, and if I decide to go Stucture Scan vs. HB; I would go base map.
