Hummingbird helix 10 questions

[Ready or Knot]

Is there a way to get the lat/lon lines up on the chart page? Do you have to have a map chip to get this ? New to the helix unit and would like to have these reference lines like my lowrance unit.

Thx .

Make sure you have it set to advanced user settings. It will allow you full access to modify the unit to your liking. It should also allow you to turn on/off lat/lon lines without an additional map card.
