I've completed the tuner kit and installed it today.

After setting up the tuner section of the Empeg to Europe and left hand stalk, the Empeg detects it OK and all functions including the stalk work fine.

The problem is that although the signal strength is at maximum, the reception is very poor and all stations sound very weak. AM is marginally better than FM which only rarely has the stereo symbol displayed and gives no RDS data at all.

I have treble-checked that the connectors are in the correct positions in both the connector body and at the PCB and the coax connection at the PCB looks fine.

I have tested it the whole thing with the car-dock on the bench (with a spare car aerial connected) as well as in the car and I have the same problem.

Does the fact that I get maximum signal strength rule out an aerial/coax connection problem?

Any ideas as to what I should be looking for or anything else I can check?
