I tried to play music from a USB flashdrive and got intermittant music followed by a message "check device".

Has anyone experienced this?

I just tried it out in mine and it worked fine. I believe the manual states only 8GB - 16GB flash drives are compatible. I just tried out an 8GB one formatted in FAT32 and worked just fine.

Mine is a 32 GB, but I think it is a 2.0 high speed....not likely compatible.

According to the manual, it's not. You can surely find a cheap compatible one on Amazon though. Could have sworn I read about a size limitation of the drive itself somewhere in the manual but now I can't locate it.

Mass storage class USB memory can be connected. USB storage devices that can be played back are accompanied by the following restrictions.
. Maximum directory layers: 8 layers (including the ROOT)
. Maximum number of files in a folder: 255
. Maximum number of folders: 512 (type A audio)/255 (type B audio) (including the ROOT)
. Maximum number of files on the device: 130,560 (type A audio)/2,500 (type B audio)

. ATAPI subclass USB cannot be played.
. High Speed USB 2.0 cannot be played.
. A USB memory that is powered by a source other than the USB power supply (for example, an AC power adapter, etc.) cannot be operated.
. A USB memory that is connected to the memory card reader or multi card reader cannot be operated.
. If the USB memory consists of two drives or more, the system will recog- nize only one of the drives after con- necting the USB memory.
. The contents stored on the USB memory may not be played in the same order as they appear on a personal computer.
. A personal computer cannot be used even if it is connected to the system using a USB cable.
. If the USB memory has a security function, the contents stored on the USB memory cannot be played by the system.
. A USB memory and an iPod® cannot be connected to the system at the same time.


EDIT Found more info on the USB in another portion of the manual:

Thanks....I have a 4GB I will try tonight.

Thanks for the post, I need to pick up a 8GB flash drive for my new Crosstrek, I guess I can buy a normal USB 2.0 8GB flash drive as opposed to a high speed 2.0?

Why would they not use USB 2? Seems very strange to use an antiquated connection, when USB 2 is the standard, and even that is switching over to USB 3.

Cars in general are way behind tech. Most laptops don't have DVD or CD drives anymore but cars still have them.

Remember 8 tracks? It's just always been that way.

Maybe this is a dumb question, is there a difference between USB 2.0 and Hi Speed USB 2.0?

The above seem to contradict each other if there isn't. AFAIK, USB 2.0 offers higher thruput rates than the older USB 1.X standard, but is there a 2.0 standard and non-standard High Speed USB 2.0 USB drives out there?

I don't see thruput rates listed on many pages that sell USB drives...

Has anybody with a 2013 model of Imprezza/Crosstrek find in the manual where it says the 8GB limit? I'm flipping through section 5 of my Crosstrek manual and I don't see any mention of the 8GB limit.... (I have tried an 8GB USB 2.0 memory stick and it works fine...)..

I'm using a 32GB SanDisk flash drive and it (mostly) works fine. It reads files correctly, play the music as it should in the alphabetical order of the folders. I'm still trying to figure out the magical theory behind the actual amount of files and folders. Everything I've found online makes no sense with limits on the number of folders, the number of files, the drive capacity, etc.

The main problem I'm having is the car stereo seems to have an undetermined limit of files or folders that can be accessed. Right now I have 281 folders and a total of 4,321 files totaling 27.1 GB. Similar to Bologna's post, the car does stop reading after right around 255 folders (not including sub-folders), but it definitely reads past the 2,500 file limit. So what is the actual limit and what is it really based on?

Also, according to Bologna's post, there are different specs for "Type A" and "Type B" audio. So far I cannot find anything online specifying a A/B difference in music files. Can anyone clarify the difference?

I guess I'll just try to get less than 255 folders in the root directory and see if that works. I wish there were definitive guidelines considering all of the available information is contradictory.

I am also using a SanDisk 32gb flash drive. Everything seems to be working fine. Type A/B I think refers to the radio not the music files. Type A is the non-premium sound system, Type B is the Harmon-Kardon premium sound system. The Nav system has different instructions all together.

What I found was that if I put 255 files in a folder, it sees them all, any more and it won't see some of the files. I don't have nearly as much music as you do, but what I do have is all playable.

I just purchased a 2013 2.5 base model and tested a 2GB thumbdrive I had ... which works, but I noticed the folder names aren't being displayed on the radio display as they appear on the actual thumbdrive. For example:

Folders on thumbdrive as they appear on computer:

2012_02_23
2012_02_24

The same folders on the thumbdrive as they appear on radio display:

1
2

Anyone know if this is typical for the base model radio display?

I had mine on a 4GB drive made by OCZ that did not work, but I switched it to an 8 GB drive made by Crucial and so far it is working perfect! Very happy.

It shows my folders just as they are labeled.

Interesting about the 4GB vs. 8GB.

You're profile says you have a limited (I've got a base model), so I'm assuming you have a large lcd display vs. the standard radio display (approx 1.5" height x 6" width). If this is the case, my suspicion is the larger lcd displays may have a more sophisticated interface into the USB ... unless you're saying you also have a "standard radio display"?

That threw me off at first, too.

"Type A" versus "Type B" are not differences in the music files -- they
refer to the audio head units. (See Owner's Manual pages 5-5 & 5-6.)

"Type A" is the standard unit in OB/Legacy base & Premium trim levels.

"Type B" is the H-K unit -- standard in Limited, optional in Premium.

2014 outback usb port

There seems to be lots of confusion about # of songs on a drive. I’ve spent the last 2 hours working on this and this is what I’ve discovered.

you can have 255 folders on the usb drive…
each folder can have 255 files (which translates to about 125 songs per folder [+ 125 files in folder index - 1 file per song] )
I can set for random play and it will jump from folder to folder playing songs.
when not set for random…. when it gets to end of folder it will automatically jump to next folder.

when all songs were in root folder…it was only playing the first 125 songs. I am using an 8GB drive. it now plays the 500+ songs loaded on the drive.
