I actually ordered a Pioneer AVIC-920BT cause it looks OEM to match the inside of the 370z. My friend had a 03' 350z that I installed this headunit in and it looked great. I didnt like the look of the new AVIC-930BT and 940BT. My brother has a Z130 in his truck and is getting the Z140 soon.
I will post some installation pictures after I get the 920BT in it. Mind you the headunit is about 3 years old, but you can buy Pioneer flashupdates for it that make it use the same firmware as a 930BT. I just like the look of the 920BT over the 930BT.
Here is what one looks like inside of the 370z:
* On a little side note. The reason why we installed this in my friend's 350Z was because the BOSE amp died. So we swapped the headunits. I have to drill through the door harnesses to run new speaker wire to the doors. Pulled out the old bose speakers. Put JL 6.5 ZRs components in the fronts and JL CS's in the rears. He got the highest powered alpine amp at the time that was 5 channels.. dont really like alpine speakers/amps/subs. Ive already been a strict JL or Focal ( when I got the budget ) guy. But I do remember installing everything that day and remembering how much a pain it was to drill through those harnesses just right to get the speaker wire in.
