I have a C80 which is about the same vintage as your C120.

I have cards that work, but forget the specific model number of the working card.

If it's a newer card, you may need to update the firmware on the C120 to the most recent. You can download the most recent from the Raymarine Web site.

A dock neighbor had a problem like this when a new card would not work on his unit. I updated the firmware on his MFD and the new card then worked ok.
