2011 CTS with Nav and Bose. Recently when I plug in a USB drive with some MP3 files on it, the system shows AUX and Searching and then a window pops up with 'This USB is not supported. Disconnect the device.' I tried formatting the USB drive and putting just one MP3 file on it but I got the same result. I have successfully done exactly this operation in the past and I could both play the files and record them to the HDD! Any suggestions?

Try a different usb flash drive to narrow problem to HU or flash drive. Not sure what operating system your car uses, but from time to time I've seen systems have an issue with an external device be fixed by using another, then back to original and it works fine. It is possible the slot you are plugging into is worn or your flash drive is and the \y are not getting along. You could also try and extension cable(or a different one if it already uses one)

Hello GR8RYD,

Have you taken your vehicle into the dealership to see if they would be able diagnose what is causing the issue between your HD and your CTS? I am sorry to hear that the error message keeps popping up for you. If you would like my assistance in setting up an appointment, or working with the dealership to address this issue, I would be more than happy to assist you. If you are interested, just send me a private message with your name, contact info, address, VIN, mileage, and dealership you would like to work with. Thank you very much for taking the time to read my post. I look forward to assisting you with this concern.

Good suggestions. I have tried two different USB drives with the same result. I even tried formatting one and putting only a single MP3 file on it but got the same results. I would be surprised if anything was worn out as I have used that USB port in the console maybe 4 or 5 times since I have had the car and it did work the first 2 or 3 times I tried it.

Thanks! I have a very good working relationship with Sewell Cadillac in Dallas already. I have a short list of other minor items for them to look at the next time I am down in that area so I will just add it to that list.
