I know that with mine, the owner had removed his from the unit. I keep forgetting to add one back in, but it's currently not reading one.When I got my Grady 12 years ago........ the ICOM radio had been programmed with a South Carolina MMSI. All my research said it's a one time thing or a factory reset. Not so, I got my new MMSI a few weeks after buying the boat, went to the manual and followed the instructions and it took the new number. The exact details are foggy after 12 years but it definitely took the new MMSI.
