Supposedly you can make the music not mute when the navigation voice is playing (Operation Manual: Page 144) and I know you could do this on the N2 that I had previously in a different car. The problem is, now that option is blacked out on the settings menu. Is this because I removed the mute wire to do the bypass? If so, then I'll have to reconnect a wire to that post on the harness, but where in the vehicle would that go since I have no mute wire on the vehicle harness (that I'm aware of). Any ideas or maybe did I just not fill out some setting?

It's blacked out because you have the AV source on. Turn it off and go back to settings.

I'll give that a shot. Does that feature only work with FM/AM and CD then?

any av source that is playing will be affected if you change the option, fm, am, sirius, xm, ipod, cd, sd, whatever. but like bleargh said, make sure that your av is off in order to change the setting

It works with all AV sources.

And why exactly do I have to turn off the AV source before making changes like this?

Makes no sense...

the same reason theres unneccessary blue boxes on the map...its just how it is

Why does changing certain settings on your computer require a restart for the changes to take effect? It just does.
