Just purchased a used 2010 Civic and want to get a USB stick to play in the radio. Is the 2010's interface a USB 2.0 or a USB 3.0 (no sense purchasing the more expensive USB 3.0 stick if it won't read any faster than a USB 2.0)

Does the radio have to read the entire stick and store it, if so, is there a limit to the memory size of the stick? I know there is a 'number of folders' limit and a 'number of files' limit, but is there also a memory limit? (Again, no sense purchasing a 64 GB stick if the radio has to read it all into memory if the radio's memory is limited)

 

Using a 2.0 or 3.0 USB stick you shouldn't have any problems just make sure you've formatted it right. As for the memory size I seen friends use all different sizes (2gb-160gb) but I think testing would be needed.

 

I tried just formatting the USB 3.0 32GB flash drive in Windows as FAT32 but it wouldn't work and the radio gave me an "UNSUPPORTED" error. I did some searching and found this DIY - 2012 Civic Formatting USB Stick for use with i-MID | 9th Generation Honda Civic Forum
After performing the steps at that link, the flash drive now works.
