Turning audio off isn't really a concern for me. I'd rather have the audio, and no reason not to. I like the Fitcamx because it blends in and isn't obvious. Which is good, because then others don't suspect it. I've seen people change their behaviors when they see a dash cam in other vehicles. About the only thing Fitcamx doesn't have is the parking mode . but that's another feature that isn't a big deal for me.I had to look up the FitcamX because I haven't heard of it before. I think it's cool because it looks integrated, but I like the features of the VIOFO A329 and the corresponding hardwire kit better. I set up my dashcam on the passenger side up near the top of the windshield and rearview mirror, to where I almost can't see it when I'm driving. I also bought the VIOFO remote to easily toggle audio recording on and off.
