I have the AVH-4100DVD, I really love this deck, but Its developed a strange problem. I have a dock for my iPhone and the pioneer ipod cable, when ever I play music, either from the ipod function of the phone or from Pandora, the deck will stop playing constantly. Sometime it will stop every few seconds, sometime it will go for a minute, totally random. I think this started when I got the iphone 4.
