I've had the main unit out of the glove box today to fit the reverse camera but now I have no DAB reception. All the cables look to be connected properly.

Does anyone know which of the many Fakra connectors supplies the DAB signal to the main unit?

Have you touched the dab connection by the aerial at the rear of the car .1aerial /2inputs ,dab and fm ,I think

Nope, not been near aerial at rear

If the code is the same as the last Fakra on my 2011 Octy it is Black DAB, Blue Satnav White FM and purple Phone

Bizarre, but all working today for some reason. I'll chalk that down to "WTF"!!!
