Hi - have had my ipad for 6 months or so now and have just purchased a component cable to connect it to my ipod dock, so I don't have to listen to my music from my iphone. My iphone works perfectly with the dock, but when I connect the ipad I just get a message up in the left hand corner saying 'dock connector'. I must be doing something wrong, but not sure what. Help please! I've gone through the user manual, but can't get any information.
