2019 4Runner, brand new G13 unit. Panasonic 86100-35364 OEM, no JBL sub. I have adjusted system, BT, and radio volume to 20. All sound sources (iPhone/carplay, radio) have very low volume, even with sound dial turned all the way up to 30. Please help.

Tips:
1.
Download above update file via your computer/laptop.
2.
Format USB drive to FAT32 Format.
3.
Copy the file “update.zip”&“hmcu.img” to the root directory of USB drive.
4.
Insert USB drive into the unit via USB cable;
then it will pop up automatically a window of update.
Alternatively, please manually go "Settings > System > System updates/MCU updates" to start the update.

When I download from the links above it's a zipped folder called update, not a file. When I extract the files from the update folder, there is not a file called update.zip. The unit will not find the mcu or update file.
3 days now and I can't drive my car. Why is an update needed on a unit that is brand new?
@Bill Anderson
Hello.
For your information, it doesn't need to unzip or rename after the download.
Please just copy 2 files to the root directory of USB drive directly.
We'll release the new firmware/MCU erratically to ensure a better user experience.
