I have a 2006 Azimut 43 Fly and simply cannot find anywhere the "black box" of the Simrad SR81 VHF radio needing attention. It is not where Azimut say it should be, behind a vertical panel in the guest cabin. Does anybody happen to have experience of this model, please?
Any information will be gratefully received.
 
I should add that I was unable to trace the wiring with a signal generator. It occurs to me that if I hold the transmit button down on one of the remote handsets, the central "black box", to which the antenna cable is attached, might give out some sort of local emission. It would be great if its possible to detect the position of that emission with a marine portable handset, a mobile phone, a walky talky, a mains ac detector or even a hand compass. I was off sick for the first few lessons in electricity at school.
Any comments, please?

Does the radio work at all? Maybe the black box part isn't even present?

You could try tracing it with a tone generator (888 Tone Generator Cable Tracker and Continuity Tester) but I imagine that won't get you a lot further than just manually following the cables.
 
My Azi has Shipmate handsets on both helms. I never needed to look for the base set fortunately. In the 2nd cabin, there was the mother of all fuse boxes. Well over 100 fuses. Had to find the one for the radio once. It was a mission. I had the wiring diagram in Italian, and although I could handle that bit, the diagram had little resemblance to reality.
My best guess is the base set is behind the lower dash panel?
 
Thanks for your replies.
The black box is there and working because one of the handsets transmits and receives. A signal generator did not seem to work. The cables disappear under a mass of other wires in the lower dashboard, but I can see the black box is not there.
Do you know if the black box gives any detectable emissions? I imagine there will be none from the antenna cable due to the screening.
 
I got hold of the correct Azimut hand book in Italian and it also said it was under the ceiling which I removed with great difficulty and high hopes – empty!

I finally found under the port side dashboard, carefully hidden behind the Raymarine autopilot box and and cleverly painted matt very dark grey, exactly the same colour as the surroundings, rendering it invisible to a torch inspection!

This all took several days but I now know my boat even better!

Thank you for all of your comments, especially Rafiki who was, in fact, right.
