UPGRADING A 1.X, 2.X OR 3.0 SYNC UNIT TO 3.2, 3.3 OR 3.4 WILL MAKE IT IMPOSSIBLE* TO GO BACK TO AN OLDER VERSION, DO NOT COME COMPLAINING TO CYANLABS ASKING FOR HELP TO GO BACK TO 3.0
* it's possible with hardware flashing but this is out of the scopes of most users and these guides.
So we have confirmed we have SYNC 3 and configured Syn3 Updater correctly, now we can get started on the actual upgrade process.
You will see a detailed overview of your current configuration at the top of the page, always make sure this is correct before preparing your USB
If the current version is incorrect Syn3 Updater may not be able to create a working USB, use the settings menu to update it
Just below the "Current Configuration" you will be asked to select a USB drive. Select a USB drive which has the required amount of storage space, Refer to the table below or the in-app advice.
|Region||Navigation Variants||Non Navigation Variants|
|Europe||32GB USB Drive||8GB USB Drive|
North America & Canada
|16GB USB Drive||8GB USB Drive|
|China||??GB USB Drive||8GB USB Drive|
|Australia & New Zealand||16GB USB Drive||8GB USB Drive|
|Rest Of World||16GB USB Drive||8GB USB Drive|
Once you have selected your USB Drive move on to "New Sync Version". Select your new region, we would highly recommend you keep the same region as your current region however it is theoretically possible to change this if you modify you AsBuilt also.
Once you have selected your region the "Version" dropdown will be populated with versions, select your desired SYNC version.
You will see a list has appeared under "Select Packages", here you can manually deselect some packages that you may not need, for most users it is recommended you leave this as is and simply press Start
You will see your install mode at the bottom left, if your install fails it's likely this is incorrect! for pre 3.0 SYNC 3 to 3.4 you need reformat, if this hasn't been automatically selected you likely set your current sync version incorrectly.
Once you press start you will be prompted a bunch of questions, once answered you will be taken to the "Download" tab.
Here you will see a bunch of files in the Queue and the progress bar will slowly progress as the files are downloaded and validated, if the download or validation fails 3 times the process will be aborted.
Once the downloads have completed and the files have been validated, they will be copied to the USB drive automatically.
You can see a detailed log of what the application is doing at the bottom of the window.
Note that the screenshot below shows 127.0.0.1 as this is our testing environment used for rapid download testing.
Compared to Syn3 Updater 1.x and FordSyncDownloader the download and validation process is much faster, at twice as fast from our internal testing.
Once the download, validation and copying is complete you will be asked the following message.
It's usually a good idea to say Yes at this point as this will automatically update your SYNC current version for future use to the new version that you have just prepared.
Finally you will be shown the following message box and once you press OK you will be taken to the relevant part of our SYNC 3 upgrade guide.
Check the USB drive and you should see the following files
You may or may not also have a reformat.lst file, this is used for reformat and downgrade modes!
