Hey guys. Still waiting on my ATS to arrive, so wanted to check with those of you who already got them. Does the CUE system allow for SDXC (bigger than 32gb cards)? Wouldn't mind keeping all of the music collection in the car, regardless of having the phone. Thanks!

Great question and I would have loved to known the answer a few days ago when I ordered a 64 GB SD card (http://www.sandisk.com/products/memory-cards/microsd/ultra-class10-with-adapter/). Given how new the car is, I figured no one would know so I decided to just give it a shot.

Once it arrives, I will let you know!

thanks for playing guinea pig. curious to know. I've already got a few thumbdrives kicking around but a large single sd would do me much better

Unfortunately, it doesn't appear to be working. I loaded it up with about 30 GB of music... put it in and the car just didn't recognize that anything was plugged into the SD slot. I put in a 32 GB that I had laying around with some music on it and it worked.

Another interesting note... it took a really long time for the car to index through the SD card and it appears that it needs to re-do it everytime the car starts? So it literally takes about 10 minutes before you can search for your music. It'll just start playing the first song of the device and when you go into Artists, etc it'll say "Device is initializing". So that was kind of disappointing. As far as large music libraries... it appears that iPod is the best way to go. Hopefully some of these glitches will be worked out in some future updates.

I've had an 80GB iPod classic hooked up (with about 30 GB of music) all this time and it only takes about 30 seconds or so for it to index through that. So you can get listening to that music pretty quickly. I don't know why it takes so long with the SD card.

I've got an android phone with a 32 gig card in it and a 32 gig thumb drive ready to take up some usb space. Guess we'll be going that route if this is as good as it gets for SD cards

Yeah like i said I've been using an 80 GB iPod classic but I just bought a used 3rd gen 64GB iPod touch off eBay that I'm going to try out as my main source of audio. From my experience, the iPod integration is the best option (at least for now). However I think the physical hard drive on the classic iPod is slowing it down a bit and might be causing the skipping that's occasionally happening when changing songs that is discussed in another thread. I had experience with a minor delay when changing songs and navigating menus in another car when I switched to the classic from my 1st gen 16 GB iPod touch a number of years ago. So I'm thinking going back to some flash memory will help that a bit.

I swear this car has a mind of its own.

So this time i went for a short drive and it handled the same 32 GB SD card (which i haven't removed) perfectly. It showed me the yellow spinner in the upper left implying (i think) that it was indexing the device. It was very speedier when changing songs (probably a full second or so faster than my iPod classic) as I expected it would be. It even found the playlist file which wasn't showing up before (that I know other people are having trouble with). All in all, it worked perfectly. When I get home I'm going to try the 64 GB SD card again but I doubt that it's going to work (UPDATE - It doesn't). It didn't even recognize it as a device when I tried the first time... whereas the 32 GB was always recognized it was just taking forever to show any music on it.

I'm wondering if the car stores indexing information on the device (if it's writable) and I just wasn't being patient enough. Because it seems like now when it starts up it has the music available almost immediately.

I agree with the mind of its own bit!

It does seem to store tags for one device only. I have an ipod classic that I use, and I usually use my iPhone over bluetooth. The other day I plugged in my phone into the USB jack to charge it, and CUE recognized it as an ipod. It gave a message saying two devices had been found, and which device's tags should it store. I accidentally chose the iphone, at which point the ipod classic music effectively stopped working - it just sat there as though it was looking for something. I had to disconnect then phone and reconnect it, choose the right device at the prompt, and then it worked. Actually it worked better, because it reindexed everything and played tracks in track order where previously it had played then alphabetically.

I can't get the USB to work at all.

So I suspect it can only handle one media streaming device at a time.

As storage capacity goes up, so does the bugs for awhile. It's why I only have a 16GB micro SD in my phone.

32GB should not have many issues in a regular SD card, but it might.

Why not use USB sticks, or a USB drive? The ATS (with CUE) has one SDcard slot and three USB slots.

Besides, at (avg) 4Mb per song, a 16GB USB or SDcard already holds 4,000 songs. That covers a very long ride.

Fwiw, I just tried out a 32GB SDcard and it works fine.

Yes, but with the native file system of SDXC, no.

SDXC cards work however you can't use ExFAT (native format) and must change over to something that CUE is compatible with such as NTFS, or HFS+ (CUE is only compatible with FAT, NTFS, & HFS+ per it's manual).
I have a 64GB I'm using right now, and with the exception of some early hiccups while it indexed and a lack of resume another time (there are certainly still a couple bugs with CUE) it seems to work just fine.
I'm going to put more on the card and see what happens, as of testing I only had roughly 5GB's loaded up.

Try that, see how it works for you. In case you're unfamiliar - in windows right click the drive, say format, check quick format, select file system NTFS and hit go.

Yeah, I know the feeling. I think I spent an hour the other night cleaning up tags. Mp3Tag is a great program if you're looking to do a ton of songs

Interesting info: I had posted on the XTS forum a question under "Technical Info on Audio System" as the manual has no reference to such technical specification. May be it's somewhere and I couldn't find it. Don't have my car yet and only had the downloaded manual and there may be other manuals. So it appears it can read a SDHC card but not the next "size" level. As to speed, is you SDHC card perhaps a slow one, e.g. Class 1 v/s Class 10? Perhaps GM can post such technical info somewhere. While some can be fixed via software updates not everything can, and how soon will a car get out of step when products it originally was able to inferface with get updated. e.g. iPhone 4 seems to work better than iPhone 5, what about the next generations of iPhones? Would the car become too soon obsolete? The manual even speeks about potential problem when updating firmware on some devices. I love new technology but start wondering about compatibility towards the future, would hate to have to buy a new car to fit my new phone, or even my present phone with new firmware LOL.

I just spent 4 days getting my all my music onto a 64GB USB stick (including converting .m4ps to .m4a which was a total PITA) only to find out this morning on my drive to work that it does't recognize 64GB flash storage. Yeah, probably should have done a dry run with a few mp3s...

That's kind of annoying considering my music library is 38GB and I was hoping to just have everything on unit. I hope they can provide a firmware update to support 64GB+. I don't really want to go out and buy an iPod classic just for this. :mad:

Thats a prime example why I believe the manual should list such technical information. Every computer I buy states details as what type of ports it has. My last Garmin GPS stated that as to SD cards I need a mini SD card and that it supports all but SDXC as to size. Come on GM, provide this data. Yes existing manuals cannot be updated but the on-line versions can and/or such data could be posted on a Web-site.

You have a total of TWO posts in these forums. Both are exactly the same. You were asked before how you know 128GB will work and did not answer. You may not realize but not everything an anonymous person says on the internet is automatically true. So, again, what do you base your guaranty that CUE will work with a 128GB card?

As storage capacity goes up, so does the bugs for awhile. It's why I only have a 16GB micro SD in my phone.

32GB should not have many issues in a regular SD card, but it might. I did not have any problems with my Class 10 - 32 GB SDHC card other than when taking it out for a further update last Friday night, it slipped out of my hand (it's certainly not in the storage bin) and after all but taking out my seats, I can't find it. Vanished! LOL. So, since my card was almost full, I am thinking of buying an SDXC card with 64GB and using UHS (Ultra High Speed - Class 1), e.g. SanDisk's Extreme Pro which supports 95MB/s thus faster than the USB 2 60MB/s (theoretical speeds of course). But given the lack of quoted specifications I have complained about for more than 6 months, I hesitate spending the large amount of money for such a card just to test such. Come on GM, please do quote the port specification. I don't even know if the USB port is USB 2 or 3 but prefer for music the SD port given the USB stick "sticks" out and both storage bins where those ports are available are used for other storage too so USB sticks can get easily damaged. Customers should not have to guess as to what is supported.

You may not realize but not everything an anonymous person says on the internet is automatically true. So, again, what do you base your guaranty that CUE will work with a 128GB card? After reading your post, just out of curiosity I tried my Patriot Supersonic Magnum 128GB USB 3.0 Flash Drive, after changing the format to NTFS and it worked without a problem in my XTS Platinum. Of course not knowing if it is a USB 2 or 3 port, I don't know what speed it uses (a USB 3 stick is backwards compatible to run in a USB 2 port but, of course, at USB 2 speed). It certainly was a lot faster to load my music on it in my PC then when loading it to my (now lost) Class 10 SDHC card. Percy615 post, however, refers to a 128GB SD card, and I am very much interested in using a SDXC UHS-1 card (<- because of speed advantage), 64 or 128 GB capacity so, in the absence of GM having quoted port specifications, I would be interested if someone actually has used successfully such a card in CUE, before buying one. Yes, for listening a normal class 10 SD card is o.k. but giving present CUE method of re-indexing each time the car is started whether or not the info on the card or stick has changed(while voice control is not yet working (*)), any available speed advantage would be of benefit. (*) Based on my experience, "shuttle" seems to change from ON to OFF ONLY each time I physically had removed the card/stick it would seem CUE can tell if the card had been removed. If my assumption is correct, why can CUE not be programmed to simply use the previous indexed data if the card or stick was not removed and forgo the re-indexing?

Because it seems like now when it starts up it has the music available almost immediately. Having tried your SDXC card twice unsuccessfully, I wonder how it was formatted? If not in a format listed in the CUE manual, it would make sense that it didn't work, but if formatted as NTSF and it didn't work, then we all would know that the SD port doesn't support a SDXC card - since GM unfortunately is not responding to the legitimate request from users to provide such information. A shame! So if you didn't re-format the Card as NTSF, perhaps you can do so, give it another try and report the outcome. Note my previous comments when using a 128 GB USB 3 stick which worked after formatting it as NTSF. But while that worked for the CUE USB port (speed still unknown), the SD port would be a different issue. I am not an expert, but I believe port capabilities are also hardware related and not just software. As to your question of storing indexing info on the device, it does not, as you can easily check when taking out the device and perusing it on your PC. Based on info I received from Cody (a CUE engineer), CUE does keep indexed data and uses it the next time you start your car, hence the fast reaction as to usability, but it (presently) always starts a re-indexing job at every car start and until that is finished voice control for your music does NOT work and CUE will tell you so if you try voice control. Obviously, if there have been changes made on the device, the old index while working for the unchanged portion as references are still correct, (as it did in my case where I had placed all albums/songs for a specific artist on a favorite button which was the sample issue I had mentioned), it would make sense, that that would not be the case as to new/changed data until the re-index is completed.

CDN XTS,

My 64gb SDXC card is formatted as NTFS and is definitely still working. I use it every day. However, I have been hit or miss on the micro SD -> SD card adapters. One worked, one did not. And the adapter that didn't work for me DOES WORK with a standard micro SD card (i.e., not an SDXC one). So just be wary of that. Let me know if there's anything else I can do to help.

Thanks a lot for your feedback. So you got your SDXC card working. That's good news for me and I am sure for many others. I can now go out to buy one. Not that readily available around in the Greater Toronto Area. I really don't intent to use a micro card in an adapter. Have a 32 GB SDHC one which I use in my Garmin GPS and use the adapter when using it in my PC. Garmin clearly stated the requirements. Micro up to SDHC but not SDXC so I knew what to get. But since the XTS has the normal size SD slot, I intend to purchase the rather pricy 64Gb Sandisk Extreme Pro SDXC UHS-1 Memory Card with a "theoretical" speed up to 95MB/s (beating the USB 2 "theoretical" speed of 60 MB/s), just to help speeding up that constant indexing. It's unbelievable that GM forces us to do these tests and communicate them to assist others, rather than simply quoting those port specs. No excuse for that. Thanks again. Great help.

UPDATE: Just received my new 64GB SD card (SanDisk Extreme Pro SDXC UHS-1 card) - which has a theoretical write/read speed of 90/95 MB/s respectively - based on the capability of the HOST device, which, as to CUE has unfortunately never been revealed by GM (*). As to my PC, my multi SD drive is connected to the USB 2 host device, so I didn't expect a faster write speed than to my USB 2 stick. Was I ever wrong!!!. I reformatted both the USB 2 stick (a 32 GB Verbatim Store N Go) and SD card, from exFat with a 128 kilobyte allocation unit size to NTFS with a 64 kilobyte allocation unit size (largest available on NTSF). Using for this test doubleTwist to transfer 3993 songs (of over 4,000 in iTunes based on 4 selected playlists) took 44 minutes for the SD card but 123 minutes for the USB 2 stick. Generated information on both devices was identical including a byte by byte comparison of those 4 playlists. Of course given doubleTwist re-generates the total layout of iTunes by Artists as previously posted on May 22nd http://www.cadillacforums.com/forums/cadillac-user-experience-cue/286639-audio-playlists-artwork-issues-feedback-solutions.html and the generation of well over thousand of additional folders and of course having to totally re-generate the iTunes playlists to facilitate this major re-arrangement, makes any calculation of MB/s transfer rate irrelevant as obviously much CPU time would need to be used for this re-arrangement. Nevertheless, the comparison of the generation/transfer time needed was impressive (USB 2 stick almost needed 3 times as much time), even though the SD drive is connected to a USB 2 host. As stated the "read" speed of CUE is a total unknown. (*) Given the SD drive in CUE is connected together with 2 USB drives from the same physical unit in the center console to CUE, I would assume the "CUE host" supports the same read speed. Yet given the large totally unexpected difference in write speed between those two devices, hopefully the read speed will also be beneficial in favor of this particular SD card to speed up the constant indexing. This of course does confirm again that CUE can handle a 64GB SDXC UHS-1 card as per this thread's question, which information is still withheld by GM (*) (if formatted per requirements for USB and SD cards which has been documented by GM). (*) Come on GM, get with it! Why do we users have to test such and report it for the benefit of other uses on this forum but potentially be out of funds if a purchased device for use on CUE doesn't work? And I assume most users are not reading this forum and are in the dark. (Even the CUE expert who recently updated my CUE system, did not have such basic technical information either).

Well, the good news for you Mac owners out there is that if you format your 64GB USB stick with the HFS+ filesystem (default Mac), IT WORKS. I just assumed it woudn't be able to read HFS+, but indeed it does. Next test will be my 64GB SD Card with HFS+.

Edit/Update: Yup no problem with a 64GB SD Card (Class 10 in this case as well!). Just format it with your Mac (use Master Boot Record Type, but use Mac Journaling filesystem, don't use case sensitive, or encryption). Copy your /Volumes/.../iTunes Media/Music/ directory to your SD Card. (So you'll have /Volumes/mySDCard/Music for example..)

Export all of your playlists as xml, open withTextEdit (or Xcode if you're so cool) and find/replace:

Find: /Volumes/<your particular path to..>/iTunes Media/Music/ and replace
ReplaceAll with: /Music/

Bonus points for running a sed script from a terminal and posting your command line here. ;)

I noted something similiar a few months back, I download top gear UK and play it either on my PS3 or Panasonic Plasma, had been using a USB 2.0 stick for this for a while. I decided one day to pep up my computers by using readyboost and went to Fry's and bought 3 32gb USB 3.0 sticks one for my work desktop readyboost, one for my home desktop readyboost, and one for Top Gear. What a dramatic increase in speed (top gear stick) vs my old stick, my home machine does not have usb3.0 but it seems that usb3.0 sticks allow you to access the maximum capability of your host usb2.0 controller. I'm guessing that is what you experienced with the SDXC card, i've yet to try this new stick in CUE though.

Based on test information on the internet using various brands of sticks and PC system, all USB3 sticks in a USB 2 port were somewhat faster than USB 2 sticks in a USB 2 port, but rather minor to the vast increase in speed when using a USB 3 stick in a USB 3 port. And we still don't know what kind of port CUE has.
