Perusing the internet may give other odd pieces of information (for example, contained in 'for sale' adverts). You might try contacting JVC support (I do not think they have anything downloadable).

Just installed a 'generic' KS-U57 (same as the KS-U58, but terminates in a RCA, $7 on ebay) that has the same black box--except I cracked the black box open and found that it is empty (only contains soldered connections). I imagine that the authentic JVC is the same.
I have a noise problem (engine static), but it is because my mp3 player is charged by the cigarette lighter--unplugging it eliminates the noise, so as far as I can tell, there is no need for a noise filter inside the KS-U57.

Go to JVC website and type in your Model # and get the Installation/Connection Manual for free. This installation guide includes troubleshooting, electrical connections, and adding other equipment. Hope this is helpful just printed me a copy.

Hi, Normally, your JVC Car Stereo will not allow direct connection to an Apple iPod. However, there are several aftermarket interface adaptor that will allow you to do so: 1. Connect the iPod to a JVC KS-PD100 which in turn is connected to the CD changer jack of the KD-G720 (rear of the unit). Set the stereo to CD changer external input setting and you're ready to go; 2. Connect the iPod to an FM Transmitter such as the Griffin iTrip (w/ Dock connector) which in turn will broadcast the IPod music as an FM signal. Operating the KD-G720 on FM radio setting will receive the IPod's broadcast music. Hope this be of some help to you. Pls post again how things turn up. Good luck and kind regards.
