Just posted a thread about my volume turning down on its own, I know this isn't where this thread goes but I want to see if others who view this forum have any suggestions. Thanks

 

Can you check the settings, I know many factory radio increase volume with speed, yours sounds like the opposite?

See if you have the setting where the volume increases with speed and for the hell of it turn it off, see if that does anything.

Also see if you have an auto mute button, I know on aftermarket stereos, I have a button that decreases volume instead of using the volume button.
