i searched for this but couldnt really find an answer... is there any way to adjust the volume of the menu beep every time i hit a button in the AVIC D3? its way to loud!

yup, there is. I just forget exactly how to get to it, but it's in the manual.

Nav Menu > Settings > Volume > Beep Volume

I did a search for "beep volume" and 3 topics came up where I posted this exact same thing. Next time I do a search for a noob about it, 4 will come up.
