Is there anything specific you find inadequate, or just the sound overall is "meh?" I'm curious if it's a speaker issue, or perhaps even the amp, or a combo of both? I don't believe you can replace the head unit as it appears to be all one piece, so I'd be curious how aftermarket would address that scenario. Perhaps an add-on or something? I haven't received my truck yet, so haven't had a chance to really push the system to see what I can do with it sound wise, but definitely appreciate the feedback.I've found this sound system to be terribly inadequate. I'd never pay $2K for it if I had the choice (came with my car). I'm a bit of an audiophile and really appreciate high-quality, rich sound. This particular system doesn't do it. I don't know how the other premium system sounds but it might be worth looking into. My local high-end car audio shop told me I'd need to spend around $5K to essentially strip out the Harmon Kardon system components and get a quality system in place.
According to the specs it does have a CD player and I think I remember seeing one in pictures.If I'm not mistaking thats just the sound system meaning the quality of the sound/song.
I think 2017 do not have dvd/cd anymore. My 17 Ghibli does not assuming 17 Levante does not either.
