Hey guys as the title suggests I can't get the sat nav to work correctly.

It won't let me put a full post code in?? It works on locations ie Manchester Airport but won't allow a full postcode to be entered its all greyed out. I've tried it on old postcodes I know have been around a long time too.

Only had the car a few months. Does anyone know if this is just an update required or something more sinister. It has a 2014 maps dvd in the head unit.

Not sure if it's related but the aerial signal is poor for dab too.

Photos below. Thanks in advance.
