Hi thanks for that, we have now tried that and that fuse is ok too.
It is a Sony unit which is functioning, was in another Mondeo and was fine in it.
What happened is that the standard Mondeo unit worked fine until it was taken out to find the serial number. We had to get the battery changed and when that happened we needed the code for the original unit. Then we decided to put in the other unit that we had from a previous car. Only to find it would not work for some reason.
Hi Brian yes all fuses are ok
