I bought a navionics card for my Garmin 66i.
I put the SD in the card reader but can't seem to get the 66i to read the card
Handhelds are NOT compatible with Garmin Navionics®+ charts. Updating or Downloading Garmin Marine Charts to a Handheld Device
This is a Garmin card containing Navionics charts, is that correct?
If so, first thing to do is to make sure you have seated it correctly. Be sure it's correctly oriented and "clicks" when inserted.
If all of that seems good, contact support.
