Actually yes... we nearly. My wife has a 103BT and the exact same problem. She bought a Lexar 16GB memory stick and just gets "unit error". When we try my PNY 16GB memory stick it works great!

Odd thing is that her Lexar works fine in my Mondeo (Sony). Seems like the Lexar doesn't support a protocol that the Alpine needs.

It came formatted as FAT32, and I've tried reformatting it with no luck.

Anyone any ideas?

I know this thread is a few months old now, but in case anyone else searching for answers comes across this thread (as I did), then I thought it would be useful to report my experience with this issue...

Tried a 32GB LEXAR ECHO ZE (the low profile one) and it throws up the same 'UNIT ERROR' message on an Alpine CDE-111R, tried reformatting as FAT32 (even though thats what it already was) but no use.

Then bought an 8GB Verbatim Netbook USB drive, which is actually smaller and sticks out less than the Lexar one and it works perfectly, without any need of reformatting and thankfully without the annoying flashing LED the Lexar ECHO has!

I don't think the shear size of the Lexar drive can be causing the error, as others have reported successfully using flash drives larger than 32GB by other manufacturers with Alpine HU's, so it would seem there is some inherent incompatibility between Lexar's/Alpine's hardware.

Resurrecting this topic because I may have solved the problem. I went thru the same issue with my HP 16gb. It continued to give me unit error until I somehow got it to work after playing around with the file organization. Right now, I have 8 folders with no more than 350KB worth of music & its working fine. I can only assume that somehow each folder is limited in size capacity because I have roughly 400+KB in a file & it didnt work. Ill continue to post more info as I continue to add music to the thumb drive.

Please can someone help me out? When I create a folder on the root of the USB with files within it (MP3's). What do I name the folder/s? I have tried New folder 1 new folder 2 with no joy. Even just 1 2 or 3. All I can do is play MP3's on the root, but not folders. Any help would be MUCH appreciated. Thanks :lease:

did someone find the solution for the UNIT ERROR on the usb drive when plugging into Alpine car radio?
My usb played fine until I added a few more mp3 to it and now get this error message
Alpine could not help me but they said I can play up to 100 folders with 100 mp3 in each which is 10,000 and I have only 2000 on it:lease:.
HELP please.

I made an account specifically for this, so I hope I can help someone with this:

I had the exact same problem with the CDE-118BT and an old 1GB flashdrive I had lying around. Kept getting a "Unit Error" on display. So I turned to the manuals online and couldn't find one specifically for the 118BT, but I found one for the HD138BT http://www.brandsmartusa.com/pdfs/manuals/20158895.pdf

In there on page 8 of the EN version it states:

"The USB Flash Memory supports only 512 or 2,048 bytes per sector."

On page 36 it says:

"Corresponding File Systems
This device supports FAT 12/16/32 for Flash Memory formats."


As well as:

"Playing back MP3/WMA/AAC
MP3 files are prepared, and then stored to a Flash Memory Device. This
unit can recognize at most 100 folders and 100 files per folder stored in
Flash Memory. Playback may not be performed if a Flash Memory
Device exceeds the limitations described above.
Do not make a file’s playback time more than 1 hour."


So that's what I did. I took the 1GB flash drive that was giving me grief, reformatted it to FAT32 with 2048 bytes per sector.
Put my music back on, and now it works.

I can't say for sure this is what did it, but I hope it helps.

Hi,

recently after reformatting a SanDisk USB 3.0 16GB unit, I encounterd the same Unit Error message showing up on the display of my Alpine cde-112ri.

I tried to reformat with varius combinations of filesystem and default allocation unit size, although unsuccesfully.

The only tool that did the trick was HP USB Disk Storage Format Tool (link). I read about the tool on a SanDisk Global Customer webpage (link).

Hope it'll help!

Best,
Luca
