so i installed a new amp in my car, for my speakers, and now all of the beeping when you press a button is gone, and there is no more voice that speaks to me...maybe it that theres something that changes where the signal goes out??

maybe you didnt hook it up correct. Am i right to assume that there is no music as well?

there is music, the music if fine...

Well you either have the amp inputs hooked up to the non-fading or rear outputs from the avic. Either of those would cause your problem. Try pushing your joystick in from a source menu and accessing the Audio settings, then Fader, and play around with the fade, front and back. Chances are your sound either won't fade, or it'll fade out when you move it forward. Or its reversed or something. If that is all correct, then your voice promts are turned off or all the way down, and so is your beep volume, and u can set those through the Navi menu.
