Bought a new chip for my Hummingbird 998c. Chip works good. My only concern is my old chip showed the wingdams on the mississippi with a black line. My new chip shows a yellow line making it hard to see. Is there a way to change this back to a black line. Navionics was closed today when I called them. Thanks in advance……
