With that setup, do you only get radio audio or does the audio from the background come in too? I've seen cables that split the audio, one to head set and another to a device (voice recorder/cam/whatever). I'll look into it. Not a top priority yet, but certainly within a few hours.
I'll check out your videos... I didn't have any plans to put mine on YouTube, but purely to use them as a learning aid for personal use. However, I will absolutely check with the FI before I even purchase a GoPro.
Thanks, so I realise, it keeps popping into my mind at odd times...
