The Helix 12 CHIRP MSI GPS G4N I have on my desk must be broken.
Using the MENU button, I get the SmartStrike setting with or without an active map curser and doing Normal or Simulator. Get the same thing using a VX regional map card or a single lake Chart Select download with the SmartStrike file. I chose a lake about 150 miles from me, set the details and have the pink icons up to the 500' zoom level and then the pink highlighting for closer zoom ranges.
