I was recently given a hero hd 960 gopro camera with only usb cable.which cable do I need for these two ports I wish to setup but without a live feed mounting this is next to impossible. Which cable do I need for the hd/tv ports as seen on top right photo.
I believe the cable you are looking for is this one on Amazon.
It is a 2.5mm TRRS jack to 3x RCA component cable.
However, this is a very old model of GoPro, and could be hard to find manufacturer's original cables.
