What Radio should i get?
 

I found a guy selling the Kenwood Excelon DNX-9960 for $700 should i do it? and will if fit perfect with my 370z?

yeah those are nice and you wont have a problem fitting it

Any double din will fit "pioneers you might want to get the dash kit the are a tad smaller than the kenwoods. Kenwood gets my vote though.

hard to install my self?

Buy it. It's the most incredible unit you can buy. I've got one installed along with the CMOS300 rear view camera.

Check out this thread. I just posted some pics this morning.

For $700, you're not buying it, you're stealing it.

NOT if you get the wiring harnesses and fallow the colors of the wires.
