I get a responce of "GPS Module Not Replying" ( or something like that).
And I did exactly the same thing.
I expected the power supply to the unit to power everything however there are two power feeds
1st - to the unit which you have already connected.
2nd - to the LGC2000 gps unit (as mark-f says). The idea is that the LGC2000 gps unit takes so little power you can have it supplied unswitched (Apart from battery master isolator) then it can keep locked on to satellites and is ready to go when you switch on the plotter.

EDIT: See you've got it all sorted now
