Well, I went to West Marine in Bellingham today, and the sales guy assures me that the Navionics Gold All-in-One #2 CF for Raymarine does indeed have all of the Canadian waters on it, even though it does not mention the word "Canada" - and the coverage illustration on the package seems to bear this out. But the big question, since neither my Navionics iPhone app nor my new Navimatics iPad app has what I am really looking for - from Lake Champlain up the Richelieu River to Sorel, down the St. Lawrence to Montreal, across the Ottawa River to Ottawa, down the Rideau Waterway to the Trent - Severn Waterway and out the Trent - Severn to Georgian Bay. All the apps pick up with good coverage at Georgian Bay. So, what CF chart chip for the C80 DEFINITELY has the coverage I am looking for?? Any Loopers out there who can answer this question?
