I've done lots of thread-searching but haven't found a fix; any help would be appreciated.
I am in the process of upgrading from APM 2.5 to APM 2.8. My problem is that I cannot get the GPS / Compass to work. It is (they are) a Ublox Neo module(s).

I have plugged in two different GPS/Compass modules: one gives 'GPS: No GPS', the other 'GPS No fix'. I am unsure whether plugging them into the flight controller has friend them - the power LED's are unlit.
The compass connector has been pugged into the I²C connector and the connector below the GPS connector.
The connector is inserted like so:
I am sure I must have missed something obvious but I'll be blowed if I can work out what it is...
