OK, I got a new Alpine and all the adapters and I don't hear ANYTHING from the speakers. I got the VW wiring harness, antenna adapter and iPod control cable from Crutchfield. As per the wiring instruction sheet, I matched color for color, but wiring red to yellow, yellow to red. I did not use the white/red wire or the pink wire from the wiring harness. I'm very frustrated, after spending at least 5 hours trying to figure this out. The unit has power and I can switch between radio and the iPod. It even acts like it's playing the iPod, but as with the radio, I get absolutely no sound, not even static. Any ideas? Am I supposed to use one or both of the wires it said not to use? Do all of the speaker wires have to have a good connection for all of them to work (kind of like christmas tree lights, if one goes out, they all go out)? If I can't get it to work, I'll have to make an appointment with Best Buy (where I got the head unit as a gift) to get it installed by them, which will be the icing on a really crappy cake.
