Hmmm, this looks interesting.
If it just uses Bluetooth, USB, or TV Out, then it might work, but I think it uses the specialized iPod connector. I'm sure it you have the engineering experience, you can strip the wires and match the Video and Audio signals and match them with corresponding signals from the Pandora.
It says "Built-in original authorized decode Apple chip, plug & play" but I really don't know what that means. Perhaps only Apple products can use it? Someone would have to clarify for me.
But I think it might be possible with some simple hardware modding. Correct me if I'm wrong.
