Comand 'Device Unavailable'
My CL63 is showing 'device unavailable' on comand screen and I have no audio. The only thing I can get to work is the sat nav (but still has no audio). I am suspecting its the HK amp, is there anything I can do or check before I order a new amp or send for repair and realise its not the problem after all.
I have already done considerable internet research but often it seems dead amps cause blank screens, my screen isnt dead, just no audio and 'device unavailable' message.
Many thanks
