Zapping Simrad/Navico AI50 MMSI

[Wandering Star]

Does anyone know how I can remove the stored MMSI number stored in my AI50?

I gather the manufacturers gave up supporting this model ages ago but presumably the fix was supplied as a SD card fix and just wondering if anyone still has a copy of the file or could loan me the SD card with the file on it - or possibly point me at a business who could do the job?

Thanks.

Maybe too late but this has cropped up on the web
