Hi all, When I return to Stella in a few weeks I will need to update my FA-50 firmware for the recent GPS rollover issue as well as install the hard-wired switch to mute AIS transmission. I am now thinking about what I will need, and wondered if I need password/credentials to clear the memory of the FA-50 before updating. I have the user "service" login/password which allows programming the MMSI for example, but is there another "dealer service" password that I need to effect this upgrade? Many thanks Dean SV Stella A54-154
