I purchased the vivid 10 for my 2015 Subaru Forester with Harman Kardon amplifier without navigation . Is there anyway you can create playlist on music player? The music files can only loaded from external usb drive. . I copy music files into the internal memory. The system music player could not load music files from internal memory. Also I notice some white noise(hissing noise) from speakers when you music pause. the noise become even more stronger when It connected to my iphone wifi hot spots. It is like bad radio connection nosie
