Starting a new thread to separate it from the navigation thread.
Thanks UoMEngineer for providing all help and updates on the subject and the Navigation thread issues.

*UPDATE IS LIVE - Sync3 3.4 for 2019+ Mustangs that are currently running v3.2 or 3.3 or a prior version of 3.4 on the MY2020.

Latest Version:
3.4.x (21098) -> July 2021


Previous Version:
3.4.54 (21020) -> May 2021
3.4.50 (20282) -> Dec 2019

First Version:
3.4.43 (20136) -> July 2019


Only version 3.4.43 has the 'infinite loop' issue based on the autoinstall.lst, and the instructions below do not need to be done to the file. Follow the Ford instructions to update 3.4.50+.

The following instructions are for 3.4.43(20136) only:
For Sync3 with Navigation:
Currently after install, the system will reboot.
If the USB is kept in, it will install the same files again. This is endless.
It will not stay on the 'Safe to remove USB" screen and I'm not sure if Ford will fix the script to add in the delay line.
Remove the USB when instructed and let the system reboot.
You should be on 3.4 after the reboot.
If you would to avoid multi-reboots, edit your Autoinstall.lst file in notepad and change the last line:
Options = AutoInstall
Options = AutoInstall,Delay

For Sync3 without Navigation;
may require multiple reboots.
Waiting on someone to report back the contents of the Autoinstall.lst file.
The last option line in the file should also have the delay(like in Nav) in order for the install to stop on the last step.

Update does not fix the displayed map version to the installed version.
It's not a real-time/file check update. It will continue to display what is already there.
It will update the MAP version in Sync 3.4 when the map pack is installed.
If you have to do both, upgrade to Sync3.4 first, then install Map Update 1.19.
If you have Map 1.19 already installed, after you upgrade to Sync3.4 you can reinstall the MAP update to display the correct file.

Anyone looking to do this get the best specified USB drive you can get. I used an older one for a previous update and it added significant time to the process compared to what others were reporting.

Tried doing it over Wi-Fi with car not running. Didn't finish before it shut down to save battery.

Will do it via USB later. Good excuse to go for a spin!

The Synch update shouldn't take more than 15 minutes, no? Can't imagine being anywhere close in size to the nav maps.

Just checked my VIN, and I'm up to date, so obviously not live yet.

Who has verified it to be live for "their" vehicle?

Hmm, yea, it says mine is “up to date” with v3.3.19052. Why is it live for some people and not others with 2019s?

Mine says "Your SYNC system (SYNC3 v3.2.18016) is up to date." What gives?
