Aveo 2011| Problem when connecting through USB port

The problem occurred recently, after I bought an 8GB flash drive.

Previously I used a 2GB flash drive which worked flawlessly (filled with around 1.5GB of music). As soon as I got my hands on the 8GB flash drive I immediately transferred all 1.5GB of music on it, connected it to the car stereo through the USB port and it worked great.
Yesterday I added additional songs to the flash drive and it was now filled with 3GB of music. When I connected it again to the car stereo it took it a lot more to read the files and after around a minute of playing it would simply freeze or it would just show the NO FILES error message.

My question is: is there a limit to the flash drive size that is supported by the stereo? (for example it supports flash drives up to 4GB or something)


Additional info:
- the flash drive is formatted as FAT32 filesystem
- the flash drive is connected to the USB port of the car stereo with a regular USB male-to-female adapter
- the cable is not damaged in any way

Almost three years later, here's the (not so) definite answer to my question - yes, there seems to be a 4GB flash drive limit on stock Aveo radios. I haven't tried many flash drives to be honest but from those I tested (around three 8+GB, two 2GB and two 4GB), all three which were 8GB or more didn't work and showed the error, and all 4GB or less worked, regardless of how much data they carried.
