Can't Access Navionics SonarCharts on Raymarine a125

[davidkuehner]

I'm looking for some help on this. I selected SonarChart data when I updated my navionics SD card and also selected to view the sonarchart data on my a125 chartplotter, but there are no depth lines shown on the display. As I sail around, the chart displays contour lines that my depth sounder has generated along the path I have sailed, but it doesn't display anything else except the base contour lines.


I sail out of Owen Sound in Ontario, Canada and there are lots of boats around that area as well as yearly fishing contests and I can't imagine that no-one else has uploaded their sonar chart data from that area.


Am I missing something? Is there something else I've failed to do to see that data?


Thanks for any help.
