Harman Kardon's Go and Play iPod boombox {Engadget}

Dec 11th 2007 3:11PM My ipod classic 80Gb's video output doesn't work with im9 so I'm thinking buying this speakers because they are compatible with my ipod. Plus, I've tried my ipod in a Apple Universal Dock and it wouldn't work either, tried on Curry's where they tested it in different Tv sets and got the refund imediatly despite the fact that in Apple store's website they say it's compatible. I bought the video cable in Currys as well.
I don't know if this product includes the cable but I wish the composite video output could work with mine because I need to make presentations in big flat screens with my ipod. Anybody tried the same with ipod classic 80 Gb ? please tell me how it went.
