I just installed mine today on an 02 alty, i was hoping to install it on my new g35 but the install parts havnt come in for the g35 and i just couldnt resist seeing it installed.
I agree, one of the best features is the built in 6cd changer. i love navi, dont get me wrong, but the 'wow' factor of navi gets old quick, but the benefit of having 6 cds with mp3s queued up just keeps giving...i have 4 cds full of mp3s, rock, hiphop,dance, chill/ambient and 2 dvd's(the office, and chapelle show)
custom backgrounds would be nice..but ehhh...the built in animated backdrops are pretty slick,
