Hey guys, I just got the 4100nex installed and it is awesome so far. I have a quick question though about the mute function. My last unit I was able to toggle between mute or attenuate and I know many other head units are like this. On this unit there is an option in the sound settings for Mute level and you can change between Mute, ATT, or off. No matter what setting I use it always just full mutes it. Reading the manual more I think this setting might just be for external devices that use the radios "mute" wire which does not apply in my case. Does anyone know if this is the case? If
