Post Informational: 2011 Camaro RS USB flash drive tests and summary

I wanted to use the USB port on my 2011 RS for playing MP3's, so I put some MP3's on an old 16GB flash drive and plugged it in and it worked, so I bought a 64GB flash drive and it would not work. I checked the owner's manual and GM web site for specifics on what drive formats and sizes will work, but found nothing useful for this vehicle. All I found was, "not all flash drives are compatible" and "only the 1st 10,000 songs will be recognized." I find this quite frustrating as you know someone at GM knows the exact specs, so why won't they publish them? I also found numerous posts from other users with questions, suggestions, and statements like, "mine just worked" which were not helpful at all. Being a computer geek, I performed a series of tests and the results follow. I hope this will be useful for someone else.

64GB, formatted with factory FAT32, does not work
64GB, formatted with NTFS, does not work
64GB, formatted with ExFAT, does not work
[ thinking the limit was less than 64GB, I tried incrementing ]
30GB partition on the 64GB drive, formatted FAT32, 32KB/cluster, works
32GB partition on the 64GB drive, formatted FAT32, 32KB/cluster, works
40GB partition on the 64GB drive, formatted FAT32, 32KB/cluster, works
48GB partition on the 64GB drive, formatted FAT32, 32KB/cluster, works
50GB partition on the 64GB drive, formatted FAT32, 32KB/cluster, works
55GB partition on the 64GB drive, formatted FAT32, 32KB/cluster, works
64GB partition (full drive), formatted FAT32, 32KB cluster size, works!

So it appears that the factory FAT32 format, with a cluster size that I did not make note of before reformatting, is incompatible, but reformatting with 32Kbytes per cluster works just fine.

Notes on Windows 7:

Windows 7 will only allow you to format drives larger than 32GB with NTFS,
so you need a 3rd party app to format them FAT32. I used fat32format, available here:
http://www.ridgecrop.demon.co.uk/ind...at32format.htm

Also, if you go into the disk manager on windows 7, you will see that the option to delete the partition is greyed out. To delete it, you need to use DISKPART from the command line that comes with Windows 7, but I am not going to post instructions on how to do so, because this is a tool for advanced users and you can easily wipe out your hard drive if you don't know what you are doing. Advanced users can seek info on diskpart and figure it out pretty quickly. If you want to use the full drive you do not need this. You can take a drive with an NTFS format, run the fat32format program above, and reformat it to FAT32 without deleting the partition or volume.

Notes on brands:
Several people post things like "brand X works" or "brand Y does not work." Brand has NOTHING to do with it. As long as the device is USB 2.0 compliant, the radio has no idea what brand you are using. It just sees a USB flash drive.

Let me know if you find this posting useful.

Out of curiosity, how many songs were you able to fit on the 64G drive?

I have not filled mine yet, but I just did some calculations for you. The exact number will vary as the size of the files vary with quality, but my MP3's are averaging about 6 Megabytes per song. Doing the math, that would allow me to store 10,922 songs on this drive, just over the max the radio will recognize.

Okay as one of the old fart generation (those who do not work in a tech related job), you are still speaking greek. Just tell me what flash drive I can buy that will work. That is about as much as I can handle. But thanks for posting this info for the tech savy younguns' as this is a very frustrating issue.

Curious to know what'll happen if you try to index more than the 10,000 song limit.

My understanding is it will begin to omit those entries. I had another USB related question a while back and was able to get in touch with one of the programmers for the radio here on the forums (codeman71). The radio only has a certain amount of memory allocated to index/buffer these songs, the number of max songs (10,000) isn't a hard coded number and may rely on the size of the files.

Here is one of my earlier posts about trying to get the indexing done right. It may be a little unrelated, but still has some good information about the system.

I had a similar issue, but was able to easily solve it. I got in touch with one of the programmers for the radio (codeman71) and found out that the indexing is done when the USB device is first plugged in or if there has been any changes to the amount of data on the device (add/remove music).

As for the order of the songs, it is based on the ID3 tags of the mp3s. I was frustrated as well when a filename would be something like "Pink Floyd - Sheep", but it would either not show up or be listed under "unknown artist" on the radio. Sure enough, the ID3 tags for the mp3s were incorrect. Be sure they are all the same as well as capitalization makes a difference.

Example: Having 2 MP3s with one as "Pink Floyd" and another as "pink floyd" will make 2 separate entries for Pink Floyd on the radio.

I had an iPhone previously and it worked perfectly with the setup. I now have Android (love it), but have to use it in UMS mode to simulate a USB stick. I'm working on an app for Android to mimic the functionality of the iPhone. When the iPhone/iPod is used, the device itself is piping the music to the radio unlike the Android/USB method where the radio directly reads from the media.

Also be aware that when using a USB stick with the radio, there is around a 10,000 song limit.

The bottom line is almost any flash drive will work, but it may not work right out of the box. Worst case you could print my post and take it to a computer shop and have them reformat it as above. I would not expect them to charge much, if anything. But if you buy a smaller drive, say 16 gigabytes or less, it will probably work out of the box.

I have a couple 16GB Sandisk Cruzers from Amazon and they all work great. Deleted the lock files that were on them and sinc them to my PC with Windows Media Player, all ripped to MP3 at 128kbps.

Been awhile since I've formatted a USB drive, but I wonder if you can make the same change to the block size while formatting for NTFS as you did for FAT32? I would imagine that it has to be able to read NTFS flash drives...

Major problems, incompatible files

While this thread started out very positive, it's going to end very negative. While my tests with a few test mp3 files worked just fine, after copying several thousand files to the flash drive, nothing will play. "No supported data found"

I started searching, and someone posted that the radio does not support special characters in file names. Mine had parenthesis, hyphens, spaces, etc. Someone else wrote that the radio does not support file names with more than 100 characters in the name. Some of mine had up to 137. So I mounted on the flash drive on a Linux machine and wrote the following Perl script to rename all the files, remove the special characters, and truncate the length of the files to 80 characters:

#!/usr/bin/perl

# rename all music files on a thumb drive to a format
# compatible with the 2011 Camaro radio format.

# where the USB drive gets mounted:
$basedir="/media/CAMARO/music";

# length of file names to truncate to (takes last N characters):
$lengthlimit=80;

chdir($basedir);
@allfiles=`find . -type f -print`;

$maxlength=0;
$renamed=0;

$count=$#allfiles;


for $i (0 .. $count)
{
$file=$allfiles[$i];
$file=~ s/\.\///;
$file=~ s/\n//;
$newfile=$file;
if ($file=~ /.*[A-Za-z0-9]mp3/) #missing .mp3
{
$tempfile=$newfile;
$tempfile=~ s/mp3$//;
$newfile="${tempfile}.mp3";
}
$newfile=~ s/\s/_/g;
$newfile=~ s/\~/_/g;
$newfile=~ s/\!/_/g;
$newfile=~ s/\#/_/g;
$newfile=~ s/\$/_/g;
$newfile=~ s/\%/_/g;
$newfile=~ s/\^/_/g;
$newfile=~ s/\&/_/g;
$newfile=~ s/\*/_/g;
$newfile=~ s/\(/_/g;
$newfile=~ s/\)/_/g;
$newfile=~ s/\-/_/g;
$newfile=~ s/\=/_/g;
$newfile=~ s/\\/_/g;
$newfile=~ s/\|/_/g;
$newfile=~ s/\[/_/g;
$newfile=~ s/\]/_/g;
$newfile=~ s/\{/_/g;
$newfile=~ s/\}/_/g;
$newfile=~ s/\;/_/g;
$newfile=~ s/\:/_/g;
$newfile=~ s/\'/_/g;
$newfile=~ s/\"/_/g;
$newfile=~ s/\</_/g;
$newfile=~ s/\>/_/g;
$newfile=~ s/\,/_/g;
$newfile=~ s/\?/_/g;
$newfile=~ s/\`/_/g;
$file=~ s/\`/\\\`/g;
$mylength=length($newfile);

if ($mylength > $maxlength)
{
$maxlength=$mylength;
$maxname=$newfile;
}

if ($mylength > $lengthlimit)
{
$pos=$mylength - $lengthlimit -1;
print "mylength=$mylength, lengthlimit=$lengthlimit, pos=$pos\n";
$tempname=substr($newfile, $pos);
print "truncating $newfile to $tempname\n";
$newfile=$tempname;
}

if (!("$file" eq $newfile))
{
print "$i: renaming $file to $newfile \n";
system ("mv \"$file\" $newfile");
$renamed++;
print "------------------------------------------------------\n";
}
}

print "\n----------------------------------------------------------\n";
print "\ndone!\n";
print "\n#of files renamed: $renamed\n";

----------------------------------------------------------------

Thinking it will work now, I insert the drive into the car. No supported data found. The cussing begins. Back to searching. someone else posted that they thought the max file length was 32 characters. Again, why can't we get an explicit declaration from GM??? So fine, I write another perl script to rename every song to song1.mp3, song2.mp3 ... songN.mp3:

#!/usr/bin/perl

# where the USB drive gets mounted:
$basedir="/media/CAMARO/music";

chdir($basedir);
@allfiles=`find . -type f -print`;

$renamed=0;

$count=$#allfiles;


for $i (0 .. $count)
{
$file=$allfiles[$i];
$file=~ s/\.\///;
$file=~ s/\n//;
$newfile="song${i}.mp3";

print "$i: renaming $file to $newfile \n";
system ("mv \"$file\" $newfile");
$renamed++;
print "------------------------------------------------------\n";
}

print "\n----------------------------------------------------------\n";
print "\ndone!\n";
print "\n#of files renamed: $renamed\n";


----------------------------------------------------------------------

It has to work now, right? Wrong!!! No supported data found. More searching. Posts say that the radio only supports certain bit rates, like 128Kbps, but my tests were with 256kbps mp3's and they worked. Again, GM WHERE IS THE LIST OF SUPPORTED FORMATS???

Even if I can determine what bit rates work, there is no way I am going though all of my songs, checking the bit rate, and re-encoding them to a supported bit rate. I'm about to give up and subscribe to SiriusXM.

As a programmer, what disgusts me is the (lack of) error handling in this GM radio. If they only support certain formats that is fine, but if they encounter a song they cannot play, they should simply skip over that song and go onto the next one, not invalidate the entire drive!!!! If I had access to the source code I could fix it myself, but I probably have better odds of getting hit by lightning than for that to happen.

I have always loved Chevrolet, but that love is fading fast because of this.
No documentation on supported formats in the owner's manual or the GM web site, very limited mp3 support, yet I can download Winamp for FREE that will play almost any mp3 on the planet. GM, you blew it on this one.

This is a little off topic, but I have a 64gb flash drive. I used it and I still have space but it contains:

All of our super8 films that were transferred to DVD format. 1973 - 1991
3 DVD's worth (6 hours). I added audio and titles to them.

I have another 4 VHS tapes of footage from my brothers graduation, my graduation, my wedding and our wedding party. (8 hours)

2550 600 DPI photos from 1975 - 2003 (5.4gb)
2622 Digital photos from 2004 - 2012 (6.3gb)

Some random other photos like a few of my parents in 1967, and I still have 24gb free.

I find that simply amazing that I have been able to fit pretty much my whole lifes moments on a 64gb flash drive.

When you ask how many files you can fit on there. Based on this you can easily go over the 10,000 file limit.

In english. Don't buy a 64gb flash drive and expect it to work without doing something on the computer.

A 16gb flash drive works.

The last part about 128 bit rate is a setting if you use CD's to make your own MP3's. The higher the bit rate, the better the file sounds, and the bigger it is.

When I first created mp3 files back in 1995 - 1996 128 was the highest the software I had would do. I believe the highest bit rate is 384 now, and the higher the bit rate the larger the files.

It has to work now, right? Wrong!!! No supported data found. More searching. Posts say that the radio only supports certain bit rates, like 128Kbps, but my tests were with 256kbps mp3's and they worked. Again, GM WHERE IS THE LIST OF SUPPORTED FORMATS???

Even if I can determine what bit rates work, there is no way I am going though all of my songs, checking the bit rate, and re-encoding them to a supported bit rate. I'm about to give up and subscribe to SiriusXM.

As a programmer, what disgusts me is the (lack of) error handling in this GM radio. If they only support certain formats that is fine, but if they encounter a song they cannot play, they should simply skip over that song and go onto the next one, not invalidate the entire drive!!!! If I had access to the source code I could fix it myself, but I probably have better odds of getting hit by lightning than for that to happen.

I have always loved Chevrolet, but that love is fading fast because of this.
No documentation on supported formats in the owner's manual or the GM web site, very limited mp3 support, yet I can download Winamp for FREE that will play almost any mp3 on the planet. GM, you blew it on this one.

OK, I can personally vouch and say that the radio fully supports 320kbps quality and is allowed to have common special characters like dashes in the FILENAME. The radio identifies and sorts the MP3s based off of the ID3 tags, NOT the filenames. The only limitation I have come across is the ID3 tag version. If you try to use some of the newer versions, it will not work. Try dropping the ID3 tag version down to 1.0 or 1.1 (cannot remember). If you have your self a Linux box (right on!), EasyTag is a good app to do this with. I've been where you are already, so I know exactly what you are experiencing. It's the ID3 tags bro, not the filenames.

Thanks for all of the good information! I'm still fighting with the stupid USB trying to get a 2GB flash drive and a couple dozen MP3s to work. I've tried every combination of format and cluster size, and no luck so far.

To whoever mentioned NTFS, I wasn't able to get the system to recognize NTFS no matter what I tried. Using Fat32 with various combinations of cluster size I was at least able to get it to tell me no supported data found, so I'm thinking NTFS is out (unless there was a firmware update on the radio I'm missing).

Tried eliminating all variables from the filenames and still nothing (I have 2 folders now, labeled "1" and "2" with songs named "1.mp3" through "12.mp3" in each, and still nothing.

I was wondering if the fact that they are 320kbps may have mattered, but sounds like at least some people were able to get that working.

Good info on the ID3 tags, I'll have to check on that and see if it makes a difference.

I get the feeling there may also be some variations in the radio firmware. I know there was at least one TSB that involved replacing the PDIM module and flashing the firmware. The instructions on the TSB to check the software version don't want to work on mine, so I'm thinking a trip to the dealer is in my near future.

What a pain...

My car came without a USB port so I bought an Android based head unit. That was OK up to 16GB SD and USB drives, but I wanted FLAC capability as well as to use any kind of drive or file format.

I got fed up and built a windows 8 PC for the dash, and now have both 64G and 265G SSD's and can transfer songs over the home WiFi or buy directly from Amazon onto the car.

Just an update, I finally got it to play for the first time. Apparently not all USB drives are created equal. I was testing using a 2GB flash drive by a noname manufacturer (branded with another company's logo and given away at trade shows) and that was at least part of my problem.

Tried out an old 1GB Lexar I had laying around and it worked perfectly (FAT32, 16KB clusters). Doing some additional testing with filenames and ID3 tags, but it's worth noting that at least some USB drives simply will not work.

I bought a Kingston 64GB off Amazon for $35, it worked great until I took it it to work to folder all of my music but in the process we had a commercial power failure at work & the PC I was using was not on a UPS so needless to say it wiped out this thumb drive. I sent it back to Amazon for a full refund & used that money to get a Sandisk 64GB @ Walmart for the same price & was able to get 9422 songs on it so far without any problems of it not being recognized by the audio system in my Camaro.

I tried two other drives one of which was another Sandisk 64GB but it's not being recognized whereas the Adata 32 GB does get recognized. The 32 GB will be my next source of music when I run out of room on the first Sandisk.

Btw, I downloaded a free program on the internet that converts just about any music format(YouTube, CD-cda, etc) to MP3 format then I burn the MP3's to the flash drive.

I have had no major problems with the 32gb Sandisk Cruzer right out of box. It is full with around 3500 songs. The mp3s range from 128kbps to 320kbps. Most are either 192 or 320kbps. Only minor issues I have found are that all folders alphabetize in 2-3 chunks...so all folders are not alphabetized in one nice list. One other minor issue is when I turn on car the USB is not always recognized. I have to unplug flashdrive and plug back in....then it stays recognized for another week or so.

The 64GB is the size of the USB drive. Imagine it as the rooms in a hotel, the larger the size the more people you can house.

64GB (Gigabytes) is equals to 64000 MB (Megabytes) is equals to 64000000 KB (Kilobytes).

Each song approximately 3-5 minutes of time are usually around 4-6 MB.
So you take 64000MB dividided by the the maximum size of 6MB and you'll get approximately 10922 songs before your USB is full.

The FAT32, NTFS, ExFAT are the type of algorithm (pattern) that the content of the USB will be saved in. Think of it as reading/writing a language whether it's English/French/German.... etc on a document.

As per 32kb/cluster. Think of it as a neighbourhood. You can fit 32 houses in a neighbourhood before you'll have to expand and build a new block of houses.

I hope that makes more sense for you. Should there be any further questions, please feel free to ask me. Thanks.
