2013 386 With Factory Stereo & Nav System

I have a 2013 with the stereo interconnected with the factory in-dash nav system. The stereo head unit took a dump and Peterbilt wants $1300.00 for a new one. My local car stereo dealer says they cannot install an alternative stereo without major wiring hacks, which could wreak havoc with the other systems integrated through the dashboard display.

Does anyone know of a adapter harness or does anyone have any insight on how I can work around this? I don't care if I lose all the other functions on the in dash screen, I just want to be able to put it all back as it is when I turn the truck in at the end of the year.

Thanks in advance

 

It's out of warranty so that's a no go. Big Rig Stereo does not list a harness/adapter. The problem is that the CD player doesn't work, the USB port is broken and Friday night the auxiliary input broke too. I really don't want to give up all my music while I try to get the thing fixed. Today I'll get the Sirius that's built in activated instead of using my XM through the aux input. I won't have baseball on Sirius or my ipod through the aux input.

My local car stereo shop looked at it & said it would take a major wiring hack to fit an aftermarket stereo, which would almost certainly require a major wiring harness replacement when I want to put everything back stock. Many of the stereo controls are actually controlled through the nav center screen and they were afraid the truck might start throwing weird codes if the nav center is taken out of the loop, so to speak. The nav center screen also presents engine gauges, truck information and other stuff that is obviously coming from the ecm. They thought of putting in an FM modulator but the antenna input can't be found, it is not a normal antenna cable/plug and apparently goes in to the nav center, not the head unit.

My carrier has been kind enough to let me have the truck for the last year of its lease while I deal with the legal BS of my truck being totaled. I just make their cost of the lease payments & run it as an o/o. I could buy it for the residual when the lease is up, but there is no way I want a new truck after my experiences with this & my Cascadia, so I just want to keep it stock until I turn it in.

I looked at the head unit last night- It's made in freaking Italy! Magnetic Marelli- the same people that made the electrics for my Ducati. No wonder it's fragile & expensive. Whatever happened to Made In America?
