I am curious exactly where others have mounted the USA-Spec device. For now, I have mine loose, under the stereo and A/C controller (in front of the gear shift). I'm planning on getting some double-sided tape and just sticking it to the bottom of the A/C controller. I'm afraid it might get too hot if I leave in on the bottom, since that's just above the transmission, and I've felt that area get hot before.
Hi Chris or any others who have installed the USA-Spec device - I am about to purchase and install the PA11-NIS for my 2007 350z Touring roadster. I was curious if you ever settled on where to mount the USA-Spec device - did you leave it loose or tape it? I was thinking it might work to put it in the passenger storage net on the passenger side. Did you have to drill a hole or anything else to run the wire from the back of the radio to the input on the USA-Spec? Thanks for any advice or pictures of the actual completed install! Hopefully I'll be putting mine in next week...
