Hi, my friend gave me his old KD AVX1, which is a JVC dvd player that has video input. Of course, I have an iPhone 3G. I did some search and discovered the following product: http://www.yopool.com/usb-sync-dock...-iphone-3g-p-18.html?currency=USD&language=en I assume this dock will enable my iphone 3G to play movies and music on my JVC DVD car player. I don't have any experiences on this kind of thing. I guess plug the RCA cable in the "Line Out" dock and JVC "video in"? The JVC player connects to my car stereo speakers. So, when I call someone, the sound will go through the Line out -> JVC -> car speakers? Thank you for reading and answering. I found another alternative: http://www.amazon.com/IPhone-Dock-S...ie=UTF8&s=miscellaneous&qid=1234137701&sr=8-4 it has video out.. but I fear only audio will work.
