All,
I just purchased the helix 12 mega chirp SI. I do a lot of night fishing. My old 997 NVB had a feature that you changed the background to blue or black via the power button menu, it changed both the map background and the sonar background colors dark for better viewing at night. My new helix 12 mega chirp does neither. It does not change the background on the 2d sonar image at all nor does it change the background colors for the humminbird ChartSelect map. When I deselect the ChartSelect to the standard base map I see that it does change that background but it is useless as there is no depth contours on the base map for my lakes. Is this a bug or do I now have to go through all the other menu options to change both the sonar colors to a dark background and then adjust the map colors manually to darker shades at night only to have to reverse all the options in the morning. If so, this is a real disappointment. What is the purpose of the background color option on the menu if it only changes the base map?
