Hi Rich,

At least the older NT+ chips that are used in my older Simrad, and some older Raymarine units, do... Not sure about the newest C-Maps, but I doubt their agreement with Explorer has expired...

There have been complaints for years about the unreliability of Navionics in the Bahamas, Explorer is definitely the only way to go...

This was pretty much spot on when I nosed into the very tight confines of Shroud Cay Harbor... If anything, I thought I might have worked my way a bit further into the creek - but, then again, my GPS antenna IS mounted on the stern rail, after all... (grin)

best regards,

Jon
