I've written the whole story here:

But the short version is this:
You cannot update the MMSI number in a Ray54 DSC VHF radio without shipping the unit to Raymarine. Nobody else can do it; not you, not a dealer/installer. I would love to be proved wrong, so if anybody knows otherwise, let us know!
You cannot enter three MMSI numbers into a Ray54 radio. You can enter one, and then it's locked.
Boat/US can transfer the old MMSI number to you, if the previous owner releases it. Mac told me about this, which he discovered when he went to obtain a MMSI number for Island Ranger. Indeed, this can be done, but not online; you have to call Boat/US (Kristin Loyd: 800-563-1536).
This helps those of us who buy boats with Ray54 radios installed. It doesn't help those who got one MMSI number from Boat/US, and later applied for an FCC license and received a new MMSI number. You folks still have to send your radio to Raymarine.
