C Map vs Navionics

[Fastfreddy]

I got a question for you guys. I just bought a different boat that has a Lowrance HDS 12 at my captains chair and apparently, I need to put one of these 2 micro chips in my electronics to be able to see detailed contour lines per customer support from Lowrance. Wish I would of known this BEFORE I left on a 2 day fishing trip!

I fish in the midwest (Iowa, South Dakota) on lakes the majority of the time but do an annual trip to Erie every Spring.

Give me the pros and cons to each...

Thanks in advance.

I bought Navionics 3 months ago thinking it would be better than the CMAP that was installed on my Simrad. It was the same..........I wasted $200.

Haha. New to me boat came with Navionics on a Simrad, I bought C-Map hoping it was better. Almost identical on Lake Erie, C-Map coverage of smaller lakes in NE indiana is not as good. C-Map went back to Amazon this morning.
