Largely based on the recommendations in this forum I changed my phone case to the smaller Incipio case and acquired the iBolt dock for my Galaxy S III. The 9 foot cable if plugged directly into the phone does play audio through my AUX in, and does charge the phone. If I plug the 9 foot cable into the dock, the blue light does come on.
When I connect the short connector to the phone, even with the blue light on, I get no audio, and it does not charge, S-Voice does not launch and the phone does not recognize it is docked. In short the dock itself appears to be defective.
As I say, with the 9 foot cable connected directly it charges and audio works so I am fairly certain it is the short connector having the issue. Very disappointing. For now I will just plug the 9 foot cable directly in and use the dock as a glorified hands free holder but I have to say I don't think I will buy another iBolt product.
