hello; I don't know for sure on the thumb drive (stick) but when I rip the CD I have the setting as windows lossless.What are the music file formats on your thumdrive? For example are they .mp3 or a lossless format?
When I moved the songs to the stick I used file explorer to drag a song to the stick.
The Honda salesman has been texting some suggestions. He says to format the stick as FAT 32 and to use either MP3, WMA or AAC.
I will try to check again but think maybe I use WMA.
