Unable to view purhased and unlocked fishing chart

[Anonymous]

I recently purchased the unlock code for the east coast fishing chart. I loaded the fishing chart on to a thumb drive. I was able to successfully unlock the chart, but I still see zero contour lines on he map. Does a setting need to be activated in order to view the fishing chart??

The chart has to be either on the chart card at the back of the machine or remain inserted on the USB. Once you unlock the chart, you should go to the plotter screen and swipe from the bottom upwards and change the chart to FISHING. You then should see the data. I recommend ranging in and out because scaling makes a big difference.
