Hello. I know that Belkin makes a plug and play for the ipod. My dad has one. This plug and play amplifies the sound playback in his car and makes the sound more full. It plugs into the base dock part of his ipod instead of via the headphone jack like in a lot of cases. Does anyone know if there is a plug and play for the zune? Or something that amplifies the playback for a zune? Thanks.
