I have a JVC Kaboom NB52B which has no line in (dumb JVC) and I need to connect a laptop to it for an outdoor movie. Anyone know of cable set that will doc on the iphone port or the usb key, this unit support an iphone dock and usb key for audio file ect but I hear many cables just wont work on the JVC boombox. Anyone have a proven cable for this. I've read several sites where a female ipod connector to 3.5mm are hit and miss.

Amazed to find that JVC deleted this useful feature:
