Syn3 Updater

AutoInstall Mode Instructions

Updated: 11th May 2022

Syn3 Updater will automatically detect the best install mode for your specific use case based on the information you provide during configuration

There are 3 install modes that will be referred to as Autoinstall, Reformat and Downgrade, downgrade is basically the first 2 combined. 

By default Syn3 Updater will use Autodetect this is the automatic detection mode, this can be overridden by changing the value in the Settings Tab however unless you know what you are doing you should keep this at Autodetect.. 

Syn3 Updater has prepared the USB drive using AutoInstall mode. (you are likely on Sync 3.2+ and are not upgrading maps)

Please follow the below steps to complete the process

  1. Insert the USB drive in to your car and make sure the ignition/engine is on, you should see the following message.

    updating 1
  2. Simply wait for the install to complete, you may see the following message followed by a restart, this is normal and can appear multiple times during the install process.
