I have a 2005 Infiniti G35x and have been wishing for years that the car had come with an AUX plug, or iPhone/iPod interface for almost the whole six years that I have owned it.  Several years back when looking for a solution, I found an interface that claimed to work, however it required the removal of the dash.  This was not an exercise that I was interested in undertaking, nor paying for. Removing the dash did not look like an easy task, not as simple as in many cars.

Fast forward a couple years…  A couple weeks ago I get my yearly XM radio renewal (another topic I will discuss in future post) and decided I needed to get my iPhone talking to my Infiniti pronto.   I quickly found out that several vendors now sold Infiniti/Nissan to iPhone/iPod interfaces.  Interestingly, USA-Spec was touting an interface that connected between the cars existing XM Radio and the in-dash stereo.  And, on the G35x sedan, the XM Radio was conveniently mounted in the trunk.  This unit also works with many other Nissan and Infiniti cars, but please take a look at the manual here to insure compatibility with your auto.

So, I purchased the unit from Amazon, and got it two days later (thank you Mr Prime).   In preparation, I cleaned out my trunk and did some searching for the XM tuner.  After popping the trunk, you will find a trim panel across the top of trunk.  Carefully remove several of the plastic pop-rivets using a blunt knife and lower the trim panel, it will still be attached to the piece that covers the rear-seats.  On the upper right-hand side you will find the XM tuner mounted in a rack on the bottom with the connecter located on the right side.  This connecter is removed and the connecter from the PA 15 – INFI is mounted in-between the two.

I simply snaked the control unit cable under the rear seats and up along the drive tunnel.  You can be ultra-clean and run under the carpets, or go ghetto and just thread it out the ski pole opening.  Once everything is connected, connect your iPhone and run through the simple setup instructions in the manual.  This will allow you to choose via playlist, artist, or song.  In addition you can run in direct mode, the cool part of this is it allows you to access any audio application on your iPhone, including Pandora!  Lastly, there is also an Aux interface that allows you to plug in any device that can connect via a 3.5mm AUX jack.

While the manual does a pretty good job walking through all the options, walking through playlists/artist/songs can be a bit tedious if you have large song collection, but a little bit of practice will help.   The audio quality is very good, the integration is surprisingly good considering USA Spec has basically just hacked the system to make your iThing look like a XM tuner or CD Changer.

In the end, USA Spec has a real winner.  As mentioned, I found the sound quality to be excellent, and installation was a breeze.  If you run into any issues, just leave me a message here and I will try to help out.
