WOW.  Thats a new one.  I know a lot of truckers have had problems with the factory nav system.  Replacing it with another OEM unit is not the olny option.  We sell a lot of the SmartNav harness so they can use a standard Din radio back in place of the factory PACCAR version.  You will loose your monitor function.  With the amount of issues Kenworth and Pete drivers are having mabe this a a warning to get rid of the

I'm doing a radio install on a 2019 peterbilt 567 heritage. Where can I get a radio to speaker wire diagram and schematics. I need to know what wires go where

You have 2 choices or actually three.  1st choice is to contact your local service dept for your brand and ask them for a wiring schematic.  2nd is to get a few test tools and go at it your self.  It can be done with simple tools and a common sense approach.  3rd and easiest way is to buy the mating harness for your truck and use it to wire the new radios pigtail to it.  All you have to do then is plug it in.  Easy right?
