It doesn't look like it. Isn't that a new model this year?

Keep in mind that installing a RioCar/empeg is very little different than installing any other DIN-sized head unit plus amplifier, so if you can fond someone who's installed anything, then their experiences should apply.

I wouldn't be surprised, though, if the Infiniti has a Japanese-style DIN slot (if it has one at all) that might make installation more difficult than if it had a real-size DIN slot.
