I found it on a website.. Idk if I can post it here.. It was pretty straight forward tho. I tried updating my Sync to Lincoln's official latest release from their very own website. It failed and broke my voice commands.
I ended up finding the 3.4 version online and used it basically just to fix what broke. Only problem is I occasionally get this error message. (Pictured)
So now I have Android auto and Apple car play but the software update requires the updated compatible usb hub all... I found it on ebay and its in the mail. I'll see if its good soon.
HC3Z-19A387-E is the part number I ordered.
