When you hold down F2 and turn on the Concert head unit and cycle through the settings, a "Nav 3" (I don't remember if it was a 3 or not) pops up as one of the parameters. Anyone know what this one is for?

Also, the front right tweeter gets really fuzzy at lower temperatures. Is it blown?

Well.. spank me hard.

...or to set the level of volume muting of the stereo when the navigation system gives voice directions.

So they have the Concert with the Nav, whereas we didn't get the Nav till the Symphony.
