I like the C-map chip way more than the Navionic chip for the same area. Much better/clearer detail and easy to read

We purchased this before our last fishing trip and it is a game changer. I would say this is a must have for deep-sea fishing.

I purchased this card for my NSX 9â€. Installed the unit and turned it on and it doesn’t seem to be compatible. C-Map website indicates compatibility, but I have been unable to reach someone there. Will update with further findings. Been almost a week and I’ve still not heard anything back from Simrad or C-Map. For $250 bucks, the customer service sucks!!**Update**Contacted Navico and they confirmed chart # M-NA-Y206-MS (NSS compatibility) is NOT compatible with SIMRAD NSX units. C-Map is horsedoodoo for customer service. If you need Baja California/ SoCal region chart for NSX you will need Chart# M-NA-T-206-R-MS. If it weren’t for Satellite/Shaded relief function, I would not waste my time, nor money with C-Map. Almost two weeks of emails as calls, and I finally got an answer, FROM NAVICO!, not C-Map.

Outstanding bottom detail and resolution. Makes the "Discover" card that came with my Simrad plotter look like a kindergarten crayon drawing.

Have not been able to use this chart at its full potential. Assumed C-Map REVEAL would be compatible with Lowrance Hook REVEAL. Sadly this will only work with higher end models (ELITE/HDS). Still, provides a bit more detail than stock navionics charts.

As new catamaran owners, we needed some knowledgeable assistance to load/operate this program but got zero help. ZERO. Only a young woman tell us to call Raymarine. I would not recommend this product unless you don’t need any help at all.

It’s a great product for the areas in which they have detail but they need so much more coverage before I’d give it 5 stars. Still worth it and hopefully they continue to improve
