So I tried some music on a flash drive in the USB jack. The MKC allows browsing and selection by ALbum, Artist etc. When I removed the flash drive and plugged in Android cellphone which also has the same music albums. I couldn't browse. I had to start from the phone and select one song at a time. Also, there seems to be a conflict on selection with SYNC 3. It's all very confusing. Can someone explain?
