Step 2: Copy The Audio Update Files To The Flash Drive
2-1
Extract the downloaded files using a program like WinZip to your computer. If you don't have a program
that handles zip files on your computer you will need to install one.
2-2
Once extracted you will see a folder named DA20. Copy the unzipped folder to your flash drive by copy and
pasting or dragging and dropping the file. The pictures below show the folder on the flash drive with the firmware
file inside of it. Note: You can NOT change the file names or folder names. The head unit will not recognize the files
if you do. DO NOT just copy the files to the drive. You need to copy the folder.
Notes:
*Do NOT store any other files on the flash drive. If there is anything on the drive besides the update folder it
will not read correctly.
*Certain manufacturer's USB memory may not work. If so, try a different manufacturer's USB memory.
