Nav Pilot 500 software upgrade

[plotzki]

I am trying to find the software upgrade for the NavPilot 500. I only could find the software for the Processor FAP-5002 in the Furuno website, but not for the control head FAP-5001 and the heading sensor PG-500. Does any one know how to find it?

Is it safe to upgrade only the processor, can the controller show the new features without upgrading it too?

Thanks,
