iPod interface issue

[bhaven]

I installed the IPod interface in the 03 JCW car with Harmon Kardon. The problem is nothing comes up on the iPOd screen except the minin wings logo. On my other 03 S without H/C stereo I installed the same interface kit and the iPod screen showed title, album cover and running time of each song. Has anyone else run into this problem. Brad
