If u need any help just ask
A quick google search finds me this http://witespyquad.gostorego.com/ublox-6m-gps-module-no-mounting-backplane.html
I haven't dabbled with the GPS side its pretty much experimental so dont get your hopes up too high about position lock and return to home.
I could never get my cc3d flying right, neither could Phil or Dave, the kk2.1 IMHO for me was better than the cc3d however the Naze is another step up the ladder!
