Looking for a Garmin Bluechart card for Cape Cod that will work in my Garmin 188c.

Good Luck. I gave up long ago. I think BigBo from this site has one. Send him a PM. Paul

I have a G-Chart which is different than BlueChart. If it is in fact the G-Chart format you are looking for, let me know.

Actually, I just checked the Garmin website and the 188/188c (which is discontinued), use the BlueChart card format. I don't think mine is compatible. Sorry.

there was a guy on SOL that had one.
you can also find them regularly on ebay.

I haven't seen one on ebay ( at least not a used one).

What is SOL ?
