I just updated my iPod touch to OS 4.0 what ever that means, now my music don't play through the interface! I went back to where I had the interface installed, the guy knew exactly what was going on. He told me I need a new part for the simple. He doesn't know how much it will cost, but the part should be in by the end of the week. I think it sucks that u have to keep spending money just to have the convenience of the iPod.:mad.:
