Well the question has been answered. The problem with no power to the radio was down to my incompetence and nothing to do with the radio or the Morgan wiring. Took the radio back to the shop who had a look and said 'have you connected these' answer no, so got home and fitted everything this afternoon.
DAB radio is brilliant as is the bluetooth and usb connection.
Apologies to Morgan for thinking it was them and many thanks to everyone for pointing me in the right direction.
In case anyone is concerned please don't worry, I don't do my own servicing!
