Nav/Radio not working

Hi all,

Back in the fold with a 2010 D4; the radio/nav is not working, the system starts with the landrover logo then turns off, you can hear a relay click, this cycles every few minutes, but screen remains dead.

Ive checked the fuses, which all appear ok.

IID tool gives error code; lost communication with audio unit. If fault is cleared it comes back immediately

Can anyone advise where to look next?

I’d be thinking the head unit (thing with CD)

Check fuses 67 and 68 if you haven’t done so already.

thanks for the comments; have triple checked all fuses this am and done a hard reset, still no joy. Thinking i may have to source a replacement head unit- anyone know the variances between part numbers for these?
