Is it possible if you hav the factory nav option?
Where can I buy the Kit?

Thanks

 

yes, to get it direct from Japan contact J's Garage: yosi@j-garage.com
I dont know if Grubbs Inifniti has the parts in stock yet. Last I heard there were delays with them so you may as well get it from Japan.
If you have a 2005 you might want to go over to the A/V forum and see what parts they're going with.
If you have a 2004 6MT, it should be pretty straight forward. See parts list below.
If you have a 2004 5AT and the titanium colored center trim (its the same on both willow and graphite, except for the willow edges).. it should be straight forward too 9again, see below).

The part #s that most people went with are what you need:

68260-AM913 (Double Dash Titanium)
27500-AL501 (AC Controller)
68475-35F00 ( Dash Pocket)
68470-60M00 (Radio mask)
28038-AL700 ( Bracket)

If you have the interior colored center trim on graphite or willow then I dont know the part #s for the dash.

Either way, expect to spend roughly $400.
To get the Navi audio cues into your spekers you will need a special adapter and a different wiring setup. It might be best to add this signal into the line going to your amps, but I'm not sure. Ask around on the AV forum.
