Upgrade Chart Plotting for HDS carbon unit ??

[Mike M]

What mapping chip do i buy if i want to upgrade my chart plotting on my HDS carbon unit. Right now I'm running on what came with uniit when I bought couple years ago. I fish western Lake Ontario and Eastern Lake Erie. Want more detail. Thanks

I prefer the C-map charts for eastern Lake Ontario. I've never fished the west end, so I don't know how C-map compares to Navionics. I use a Carbon 12 on my boat.
