The group MMSI is established by modifying the MMSI
assigned to one (1) of the group members. The last digit
of that member’s MMSI number is dropped and a zero (0)
is inserted at the beginning. For example, member MMSI
number 366123456 becomes group MMSI number
036612345.
Group MMSIs can be entered and changed any number
of times without encountering the need to have your
radio reset.
