Solana,
Thank you for your inquiry.
Without know specifically which/what equipment is installed as part of you navigation/radar suite it is impossible to say for 100% certainty.
Yes; The MFDBB is capable of the radar / chart overlay functionality BUT there are certain conditions; Do you have a Furuno DRS radar sensor installed as part of the system? Is there a position sensor, like our GP330B or BBWGPS, installed as part of the system? Is there a 10hz heading sensor, like our PG700 or SC30 satellite compass, installed as part of the system? all of these are necessary for this functionality.
Which AIS receiver is being utilized and how is the data being fed into the NavNet 3D MFDBB?
