Just applied update to my Helix 9. Now my Lakemaster maps colors/highlights no longer work. Came here and I see others had same issue. Humminbird says "oh yeah, sorry. We will fix that with the next update. In the meantime, just suck it up".
Not to mention every time you update then it resets everything to your DEFAULT settings with is a real PITA. We spend all this time getting our units setup like we wan't them and then all our settings are erased everytime you update. I have learned my lesson - no more updates for me. The cost always seems to outweigh the benefits when it comes to these software updates. As much as we spend on these units to purchase and install them, then updates shouldn't be such a pain. And I am a computer programmer so I have some understanding of 'software development' and 'software testing'.
In addition, others have reported other issues in addition to the Lakemaster color/highlight issue. Hopefully I can help someone else from being stupid like me and trusting Humminbird.
