.opus on JVC KD-X33MBS car/marine stereo? 2019-10-30 16:46:33 The most recent firmware that I have for the above JVC stereo does not play .opus. I was wondering if there is a way to flash it such that it can play .opus files? I'm thinking of how RockBox was flashed to media players...Is this something that is being done or can be done? I'm not holding my breath but thought HA would be a good place to start.
