Introduction
This installation manual is designed to take you through the step-by-step installation of the firmware version
iLX-407_1.0.11(2021.08.10) update for the iLX-407. Please familiarize yourself with the owners manual (found at
www.alpine-usa.com/support) and if you still have additional questions please call 1-800-TECH-101.
This firmware update corrects issues with the following:
Fixes wrong status display of Sub.W Level & Sub.W Phase.
Step 1: Format The Flash Drive
1-1 Only flash drives formatted to FAT32 can be read by the head unit. This means that your flash drive can
not be formatted to anything else including NTFS, exFAT, etc.
1-2 In Windows the drive can be formatted by right clicking on the drive in file explorer and selecting format
as shown in the pictures below.
Caution!
Do NOT turn off vehicle’s ignition or head unit’s power switch while updating. Some modern vehicles may
shut down the ignition (ACC) if the engine is not running for some time. If you are not sure if this applies to
your car, leave the engine running while the update is in progress.
Do NOT remove the USB flash memory while updating.
Do NOT press any buttons while updating.
Do NOT update while driving.
Failing to follow any of these cautions could cause damage to the head unit.

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.

Step 3: Copy The Update Files To The Head Unit
3-1 Plug the flash drive into the USB connector of the head unit. The USB extension is typically ran from the
back of the head unit to either the glove box or center console areas of the vehicle depending on the
original installation.
3-2 Turn on the vehicle’s ignition to power on the head unit. Do NOT turn off the igntion or the power of the head
unit while the system is updating!
3-3 The “Update” screen will automatically pop up. Select “Yes”. The file update preparation portion will start and
takes about 2 minutes. The head unit will then reboot.
3-4 The update process will then automatically start. This process should take about 2 minutes. The head unit
will auto reboot several times when the update has finished. That will take about 2 minutes. Once the popup for
the software is installed comes up press the “Ok” button
3-5 Remove the USB drive. Check version iLX-407_1.0.11(2021.08.10) in the about settings. As always, to get into
the setup menu engage the parking brake, release the parking brake, and engage the parking brake again. Then
go to “Restore Factory Settings” in the about section to do a factory reset.

Troubleshooting Guide
Symptom Possible Cause Remedy
1
Head unit will not read flash
memory.
The downloaded software was not
unzipped.
Refer to Step 2. The .zip file will need to be
unzipped first using your program of choice
(for example, WinZip, WinRAR, Izarc, etc).
There are other files on the flash
drive.
The flash drive should be freshly formatted
(refer to Step 1) and the only files on it
should be the downloaded files as shown in
Step 2.
The file folder name was changed
or put into a different folder.
Make sure only the file that is shown in step
2 is copied over.
The USB port was installed
incorrectly.
Make sure the port is working correctly by
plugging in an iPod or flash memory with a
few MP3’s on it and seeing if it will play the
music. If that’s not working then there’s no
way for the update to work. Try plugging the
flash drive directly into the tuner without the
extension cable.
