Apologies Glen, I forgot to insert the link to
MGMarc's post which I have now done.
My theoretical diagnosis is based on the following:
- The faults didn't exist before you installed the DAB unit.
- All the faults involve equipment linked to the K-bus.
- It's known that one poor K-bus connection results in odd behaviour from other equipment connected to it.
- Pushing an old aerial down the back of trim without line of sight is risky!
