I found a post describing success changing the MMSI on a simrad
NAIS 300, and a Raymarine
It doesn't seem to be working on my NAIS 400. I wonder if the password is just different. Does anyone know how change the MMSI for this unit?
And before anyone tells me it is "illegal", I have yet to see anyone provide a link to the actual law or regulation saying programming my own MMSI is illegal. I *have* seen that it illegal to program in incorrect MMSI, which is not what I'm doing. I've purchased a foreign boat
, and now have a new US MMSI. Even if it is illegal, I'll take the punishment, whatever it is, that authorities want to hand me for changing an invalid MMSI to a valid one on my own property.
