Software Update Procedure

7-inch Shallow-Chassis Multimedia Receiver With PowerStack™

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

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.
