andyhyoung,

Apologies for my delayed response ... holidays and bereavement have put radio codes on the back burner.

Not sure where I am up to, but think we have tried both the M and V codes. Neither have worked.

I suspect lack of success might have something to do with the serial number - we are using the one produced by the radio. Perhaps next step might be to check the back of the radio?

If it is okay with you, I will come back to you when we get the balling rolling again!

At the very least you have saved wasting money on serial numbers which are seemingly incorrect
