Here's the link to the ice-link that i used on my nav unit. I checked my original head unit and it has the same plug in terminals as the nav unit. You have to order the one for the Becker head unit and what type of holder you want for your ipod. I used the docking cable and put the ipod in the glove box. Hope this helps.
