the Z1 does not have any type of graphical display like that whatsoever. look into the avh-p6800dvd if you are looking for a double DIN unit with awesome visual graphics & displays.
the z1 definatly has an eq. I have mine tweeked perfectly. What a huge difference in the sound it has made. I had a 100% stock system, all i did was the z1, HUGE difference.
while you are in an audoi mode push the av settings button i think it is, then on top there are two tabs one for audio and for system i think. All the audio options are off course in audio.
Man, that's nice.
I have no use for the DVD changer, but I want those visuals!
Not really worth spending $300 more than my AVIC-D1 cost to get pretty visuals right now though. :(
Maybe next year's AVICs will have visuals, or maybe they'll come out with a single disc version of the 6800.
