I recorded sonar data using my Echomap CHIRP 44DV. I could see the contours appear on the screen of the fishfinder and was delighted with the results. When I brought the SD card to my computer, I found several files with names that are obviously coordinate based. When I clicked on one of them, I got the following message:
"/Volumes/NO NAME/Garmin/Quickdraw/Contours/N571998208W1097596928/N571998208W1097596928.qdc" could not be imported.
In Basecamp, I saw a reference to what must have been the data listed as ADM... Clicking on this, nothing happened.
In an internet search, nothing useful came up on "Quickdraw". In the Garmin forum, nothing.
I downloaded Homeport. While in Homeport, I again clicked the "/Volume/..." file. The Basecamp application immediately opened and gave the same error message.
How do I get the beautiful map I saw on my Fishfinder into a file on my computer?
