My sound skips/hiccups randomly, more so with the navi on. It is annoying as all hell. I searched and havnt found a solution... I guess the firmware update didnt fix it either (I havnt updated yet, if there is one available). I have the AVIC-F700BT. Previously had the AVIC-D3, didnt have any issues like this with the D3...

I too have the same problem.

Also, none of my voices for US English work, so what I was thinking was the problem is that NAVI is telling me to turn right on the next street, stopping the music to tell me that and then turning it back on.. Problem is I don't hear the "Turn Right" part either.

Ive noticed that mine does that as well when approaching a turn. I have not modded any of the voices yet but I do have the voice volume turned down all the way. It is in the nav software.
