I was using the Avic Z1 then upgraded to the latest maps making it a Z3.

One difference I noted is that before the upgrade, when the voice navigation lady was speaking, it would slightly mute the audio that was playing (either radio or HDD or whatever).

Now, after the upgrade, the audio plays at the same level , and the lady is speaking at the same time.

anyone else experience this? Anyone have any idea how to fix this?

The sound for both are fine, its just a little overwhelming hearing the music and the navigation at 100% at the same time.

Thanks

Go into your system settings, the option is in there. I believe it's called "Mute Set" or something like that, you'll see some options that are "Nav/Phone", etc.

I'd go out and look at my own unit but it's 4 in the morning and I just don't feel like it. It's not hard to find though.

@CaptainInsaneO : Thanks! You knew exactly where to go!

Glad you got it sorted.
