If you installed T style on your Auto AC Fusion and experiencing low volume but your AC is functional on the new unit, please use the software below to fix the issue.
Or if your factory radio does not come with an amplifier but you have an Auto AC, please use the file below.
Steps to update the system:

2. Plug in the flash drive to the radio, then go to settings on the top - go to system info - MCU update - MCU update
3. A progress bar should appear. Once it is completely, the radio will automatically restart.
