At certain points during the update installation, the screen in your vehicle may go dark as the system reboots. You will also hear audible “Installation Complete” messages. They refer to specific phases of the installation, not the overall upgrade process.
- Ensure you have already downloaded the updates to your USB.
- Please ensure that your car is in a well-ventilated area. Your vehicle will need to be turned on, with the engine running, for about 20 – 30 minutes to complete the upgrade.
- Plug the USB in and wait until the screen displays “the update will last about 30 minutes” message. Press OK to start the installation.
- Wait at least twenty minutes to check the screen. Press OK and remove the USB if the screen displays “You have successfully updated your SYNC™ software to Gen3 – Vx.x” message. The upgrade is complete.
