Hi,
I have a JVC KV-AVX33 installed in my Honda Fit with a center channel by Alpine. It is an older model than yours with the facility of playing DVD-Audio,
something that JVC is no longer including in car players, a shame
.
But with Audio Muxer I can encode all surround music I have, including the dozens of self made DVD-A's in my collection, and I carry them all in flash players (DataTraveler by Kingston). By now I have 1 32Gb, 2 16Gbs and 2 8Gb, with mpgs (surround), wavs or mp3s (stereo).
2 things are very important:
a) Your JVC will not accept an HD like My Passport, it has to be a solid state flash player, because they don't need to drain energy from the USB port on the JVC.
b) Don't mix mpg with other kind of files in the flash player. If you have one wav file and 2090 mpg files, JVC will recognize only the wav file and will not play the mpgs.
I don't burn music disks any more.
Have fun.
