First, let me apologize. I know this or a similar question has been asked before but some of the threads were kind of old and I can't seem to find a clear answer. I bought a 2014 LTZ two weeks ago. The USB port is being all kinds of difficult. First, all of my music is on a 2nd gen iPod Touch. When I plug it into the USB nothing happens. I mean nothing. Doesn't tell me it's unsupported, doesn't recognize the iPod on the MyLink, doesn't even charge the iPod. I've also tried 3 separate USB sticks and none of them were recognized.

However, when I plug my Galaxy S4 in, it does charge the phone. So that would lead me to believe that the USB port is functioning.

I spoke to the Infotainment people and they told me 2 things. First, you can't use Android devices to play music through the USB interface. It will apparently only work with AUX or Bluetooth Streaming. Second, they said it might be a song compatibility issue. iTunes downloads everything in .m4a and that's not a recognized format (which makes no sense at all). So I converted one album to mp3 format and put it on a USB stick. NOTHING.

Does anyone have a current fix to this problem? I'm tempted to go buy a new USB stick since the ones I've tried are at least a couple of years old, but that couldn't possibly be causing a problem could it?

Try formatting your thumb drive to FAT32 (not exFAT, or anything else). A lot of infotainment systems are only compatible with the very dated FAT32 file system for whatever reason, but Windows will format USB drives to exFAT (a newer, better file system) as the first option. If your thumb drive is larger than 32GB you'll either have to accept a smaller size, or look into the workarounds to make larger allocations for FAT32 in Windows.

Ah ok, I'm gonna go get a new USB drive then. The ones I've been using to test are just small office ones, and are FAT16. I'll go get a larger one capable of FAT32 and see if that works. Thanks for the suggestion!

Ehhhhh, I'm not so sure about that. True, it's not going to work like a iPod, but I think most Android phones will emulate a USB stick (although you have to do some things on the screen first).

But that said, I prefer to just leave a USB drive plugged in.

Also keep in mind the usb jack will not charge the newer smart phones with their larger batteries, the usb jack is current monitored and if over the usb 2.0 1/2 amp spec the jack will shut down, got to charge with the right cord and 12V outlet-the new smart phones are using the usb pins to determine how much to charge the phone-at what rate and you need the apple or Samsung cord or they will not charge at the fast rate, the usb jack is out of the loop charging wise and once a overload is detected it will not allow data either

You can reformat your existing drive quite easily. Start Menu --> My Computer --> find your disk --> right click --> format, then make sure FAT32 is selected for file system, leave the default allocation size, enter the label you want, and make sure the quick format box is checked.

You may be right. I didn't really test it as my main goal was either the iPod Touch or a large USB stick. Although for my Mac I have to have the Android File Transfer app downloaded for the phone to be able to talk with the computer. So maybe that's where the issue is?

Ok here's another question for you. My wife has a 2013 Equinox. Her iPhone 5 works perfectly fine in it. Charges, plays iTunes, everything. But when I plug it into my car I get nothing. No charge, no recognition. I'm assuming the MyLink software is the same, but if not you'd have to assume mine was the newer version. So how come hers will play and mine won't?

Don't know about the equinox usb ratings but the newer phones can charge at up to 1.5A and the usb spec in the cruze is only .5A and if exceeded will shut down the jack both data wise and charge wise, it's possible the phone can be almost charged and be under the shutdown threshold and work OK and another time needs over the threshold and not charge, the new phones also use the usb data pins to tell what rate to charge at and the apple and Samsung OEM charge cords have resistors to set the charge rate, there are 2 types of usb cables now-one is a charge type and one is a data type

Ok, good to know. Thanks a lot for the info! Last question. If the charge rating is exceeded and the jack shuts down, does it automatically reset itself after a period of time?

FAT16 and FAT32 will both work. It's the exFAT (mentioned by zen_) that won't work.

I think it resets as soon as the overload is removed or next key cycle, got to use a usb data cable for music through the usb jack or stream if you have Bluetooth media interface on your model, I think 2015s all have it

Ok, well I've now tried the flash drive formatted as FAT16 and FAT32. Neither work.

I'm just so frustrated with the whole thing. It will charge my Android phone, but won't recognize anything else I've put in (iPod, iPhone, USB drive). If the Infotainment people are right and Android is not compatible for streaming music through the USB, then I've got to assume the problem is not actually the USB port but whatever interface the car uses to recognize music devices.

I don't really know where to go from here... I guess I'll have to take it to the dealership.

Sounds like a plan. I suspect either a defective connection that has a open data line, or the interface isn't enabled for some reason.

I would suspect that as well. It could be that the data pins are bent in the connector, but the power pins are okay. You might need a new cable from the headunit to the glovebox. Look at the connector to see if it's mangled. I posted the pinout below.

You guys may very well be right about that. The connector has looked off to me from the beginning and there seems to be much more "wiggle" room than there should be. But when the Android powered up I figured it was just me. Thanks for the picture, I'll definitely check that when I get off work. Got an appointment with the local dealership Friday morning, so hopefully this will be my last week with this problem.

IIRC, the power leads may be longer than the data leads, so if it's not seated all the way, it could cause that.

Chatta, if you get a chance post a pic of what it looks like just for curiosity. It could be the iPod cord as well, or a combination of both. Working in networks, the first think I always check before anything else is the physical connections before I check the device/firmware. Here, we can use the same troubleshooting steps. Rule out the "physical", then go to the higher levels (USB drivers/kernel) if the connections are okay. Let's remember that these mobile phones and ipods are just micro-miniature computers.

Sidenote question and might be off topic. Has anyone here replaced the USB cable, or is it integrated into the headunit's wiring harness? I wonder how easy it would be to swap out.

I've only seen the console end - I think it's a separate wire. Probably not too hard to change once you have everything opened up, but it's not a generic USB cable as it needs to lock to the back of the port. Bottom line, dealer part.

I didn't get a chance to work on it last night, but I'll try and post a pic tonight. I have tried 4 different iPod cables and my wife's iPhone 5 cable, so if there's a problem with the connection I think it's probably the car. I don't know if it's part of the headunit's wiring harness. I do know that the USB and AUX are two separate wires coming from the arm rest and they seem to run down different sides of the center console (USB comes around to driver's side and AUX seems to stay on passenger side). So maybe that means they're separate from the wiring harness?

Never did get a picture, but wanted to let you know it looks like you were right. Took it to the dealership last week and they said 2 of the pins were bent down. So they're ordering a new USB cable. Thanks for the input!
