Both my AVIC and Dodge are fresh from factory and under warranty. Dodge has the factory Alpine system. When it is cold and until the truck/unit warms up, the left channel cuts in and out. I have pushed my fade settings to top and left to isolate this and when it cuts out, sound cuts out entirely momentarily. Dodge techs have crawled through their hardware and confirmed Aokay. Pioneer tech doesn't know what it could be if it is temperature related. Both are warrantied items, but neither vendor wants to be left holding the bag so they are pointing fingers at each other. Help!

Pioneer units are notorious for this. Been that way for years.

do you have an adaptor in there or is it just a plug. check aftermarket plug for bad connection. jim
