Is your 30 gig iPod a new 5G or the old style? It makes a difference. I?m fine with the speed of the Nav controls. I can tell you that the older firmware and the older iPod it was slow, with the new firmware the older iPod is faster and the newer iPods less than 1 1/2 years old are faster yet.
I would some times like to use the iPod controls, I do have about 8.5 gigs of music and 18gigs of videos and the iPod plugs in to my DVD rear ent. system. So I will be able to start and fast forward movies and look at the iPod display to.
The extra harness was for applications that had a CD changer.
But I was told that the extra harness would also help with the noise if I had any. So far I have no noise. Let me know if that extra harness helps out any. Also see if it lowers the sound quality of the iPod any. You might try to move the X2i around it could be picking up some interference from something close by. The data wire on these dam GM?s are not shielded.
Good luck.
