Lack of detail with Navionics+ charts

[jeff]

Ben,

I am having a similar issue on my c95 display after updating the software to version 17. I also updated my navionics chart subscription. Charts below my current latitude resolve with all the detail you would expect. Charts above my current latitude show no detail and just become blurry when you zoom in. My chart is the pacific northwest, Seattle etc. I have reloaded the software, restored the MDF to original settings but it makes no difference. Please let me know if you learn anything new. And, my MFD says it could and did take a screen shot. I have seen other artifacts as well such as sections of the chart disappearing for a time then returning. It seems to relate to my location. I don't think intermittent behavior is a Navionics problem.
