I have been searching for a few hours for a dual din head unit for my Z and I came across this one at Sony/Crutchfiled store. It is the Sony WX-4500x (I did a search on my350z but did not find any threads on it). Here is the link.

Sony WX-4500x

Here are the drawbacks I see.
1. I am not sure how many pre-amp outputs there are (thiey list one for a sub listed).

2. Does it have XM sat controls?

I am going to call crutchfield on Monday.

Also, for comparison there is one by clarion that

Clarion Dual Din

I just can't believe there are no other us spec dual dins that will work
