Is Navigation DVD or CD based? how do you like it? Are there voice commands that you can give it?

Also, has anybody wired a bluetooth kit to the back of the radio? If yes, does the radio use ISO plugs or are they custom ones? Is there a MUTE radio lead?

Thanks

 

NAVI is CD based. I like it fine. No, you cannot give the system voice commands. Only she (NAV) tells you what's going on.
Dunno on the BT stuff...

 

Even 2004s are CD based? hm...how is the interface? How do you enter street names and stuff?

 

You enter street names and all using the little joystick-type interface/buttons on the dash.

As for adding BT, your best bet would be to use something like this:
