I have just bought a H&B CA-5555 in-car MP3 player (from pixmania for £85) with USB port on the front (http://www.hb-direct.co.uk/EN/P_68.html). I have tried to connect a 3.5 Hard Drive via a EASY IDE 2.0 USB adapter but the unit would not play the MP3s properly. It read the ID3 tags and played a second or two of a track but then nothing! So it CAN work but HOW DO I SET IT UP TO WORK RIGHT??? could it be the 3.5 HD? would a 2.5 laptop HD work? or maybe is it the easy ide adapter i'm using? (The H&B Mobile Multimedia AV-512 is supposed to work according to H&B http://www.hb-direct.co.uk/EN/P_46_5.html) cheers in advance jon.
