Troubleshooting Guide
Symptom
1
Head unit will not read flash
memory.
Possible Cause
The downloaded software was not
unzipped.
There are other files on the flash
drive.
The file folder name was changed
or put into a different folder.
The USB port was installed
incorrectly.
Software Update
iLX-407
Remedy
Refer to Step 2. The .zip file will need to be
unzipped first using your program of choice
(for example, WinZip, WinRAR, Izarc, etc).
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.
Make sure only the file that is shown in step
2 is copied over.
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.
