I like to use the USB port on my 2013 CT200H non-navigation audio system to listen to music MP3s. But have run into what seems to be a limitation in the size of a USB memory stick that the device can handle.I have a 16GB stick with mp3's that works reasonably well. And the number of sub directories,files etc are well within the capacities cited in the user manual. But if I use a 32 GB stick I get a USB #4 error message. I can't find any error message numbers in the documentation. But if I take the same files and put them on an 8 GB stick then it works correctly.

## Can anyone direct me to documentation or other details of the audio system or where they might be available.

Another aside is that when I look at the memory stick, formatted at the factory, with
fdisk on linux I get the following partition layout which is rather odd in that supposedly
it is one partition of type DOS and shows up as 4 subpartitions and the unknown
types:
Disk /dev/sdd1: 14.5 GiB, 15504310272 bytes, 30281856 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

I have a 32GB SanDisk stick in mine and it works fine. What's annoying though is that it lists albums in the order I put then on the stick, not in alphabetical order. Given that there is no screen it can take forever to find a specific album.

I agree on the long time it takes to list the albums. I also have a 32GB stick. Is that maximum? Is it any idea to get a 64GB or 128GB stick? On my old car I had a (quite inexpensive) Kenwood stereo and it could even handle 256GB sticks.
