Show Settings
The Show Settings screen will show you information about your vehicle, the GT, and your current vehicle settings. This screen will also indicate if
the GT tune is currently installed or not installed on a vehicle.
Uninstall Download
This option will allow you to uninstall the tune from your vehicle. This process is very similar to installing the tune, so be sure to take the same
precautions listed on pages 32-35.
You can find more information about uninstalling the download on pages 38-40.
Update Firmware
This option will update the software on the GT itself from the files on the Micro SD card. This is an important final step to the update process. See
pages 20-27 for more information about updating your GT.
