i just got a brand new iPod with the dock. the dock has a line out which is the main reason i got it. so i don't have to worry about the headphone jack causing distortion. well the exact opposite is the problem. the line out bypasses the volume control. and the output must be hot enough that it distorts at the head unit.
when i looked in the book the speccs about the aux input on the head unit had a o with a | thru it that said 3.5 and someone said that might mean impedence. i can't find any information on the iPod's line out from the books. i'm going to get on the phone with apple to try to get some more details.
is there something i can do to lower the level so it doesn't distort the head unit?
