Locate the USB drive that you recently used to install the SYNC software update (or run the SYNC Version Checker) in your vehicle. Insert it into your computer's USB port.
On the next step, you'll upload a log file that SYNC placed on your USB drive when you successfully installed the software update or finished running the version checker. This file lets us know which software version your SYNC system is running, and we'll update your account accordingly.
Can't find the USB you used for your last update?
Use the Version Checker tool to help determine which software version your SYNC system is running.
