I have read hundreds of threads but can't seem to find one addressing my personal problem. when I plug my ipod in (and I have the pioneer cable which I had prrofessionally installed) the ipod will play and even the skip and and everything will work. Then after about a minute, everything freezes. The ipod keeps playing what it was playing, but the only button that works is volume. Can't change channel, touchscreen is disabled, menu button doesn't work. Any ideas?
