I can now confirm that the gopro cable from amazon records in stereo, my setup is, autocom on bike with pillion to rider mic's and headsets all connected via the autocom to a zumo 660 satnav for directions and listening to music, i have now incorperated the gitup git 2 so it records video and everything you hear from the satnav and also all you hear from rider to pillion and pillion to rider, and now i am happy, all i need to do now is find out what was causing the white blobs on video, a new housing has been ordered so we will see what thats like.
