Our take on the PAC AAI-NIS2 Auxiliary Input Adapter

by Ken Nail

This AAI-NIS2 adapter from PAC lets you play your portable MP3 player or just about any other external source through select 2003-up Nissan and Infiniti factory radios. Hookup is simple — the adapter's included cable plugs directly into the back of the factory radio. Your factory radio must have either a "SAT" or "RADIO" button to use this adapter. Warranty: 1 year.

Note: You must use the satellite radio input of your stereo to use this adapter. Please enter your vehicle information or call a Sales Advisor at 1-888-955-6000 to find out if this adapter is compatible with your vehicle.

Features

Overview: The PAC AAI-NIS2 Auxiliary Audio Input Adapter allows direct input of any preamp level audio source to Nissan and Infinity factory radios that are satellite ready. This adapter eliminates the need for sound degrading solutions like an FM modulator.

Compatibility: The PAC AAI-NIS2 is compatible with 2003 to 2006 Nissan and Infinity vehicles that feature a factory radio that is Satellite ready (XM or Sirius).

Note: There is a switch on the AAI-NIS2 that will allow this unit to work with or without the factory Satellite receiver present.

Two Auxiliary Inputs: The AAI-NIS2 will accept up to two separate external audio sources such as a DVD player, VDP, MP3 player or Satellite Radio using the interface's two sets of stereo RCA auxiliary inputs. The two auxiliary inputs will be selectable from your factory radio.

Installation: This interface plugs into the back of the factory radio using the supplied harness.

Note: Unit does not install in rear of vehicle.

Steering Wheel Remote Compatible: The AAI-NIS2 is also compatible with your factory steering wheel remote controls when used with the optional PAC SWI-X steering wheel adapter (sold separately). The AAI-NIS2's yellow/black wire connects to the optional SWI-X's yellow wire for operation.

Quick and Easy

Written By Glenn, Austin, TX on Wednesday, May 12, 2010
Crutchfield Customer Review (What's this?)
 
I installed this in my 05 Altima SE-R and it works perfectly. Had the dash apart and hooked up to the radio in less than 5 mins. You do have to turn the radio up a bit, but the sound is crystal clear. It also doesn't come with the Y adapter to hook it up to your mp3 player, so make sure you go out and get one before you start the install so you can hide the wire.

Great Product

Written By Drew, Greensboro, NC on Monday, October 05, 2009
Crutchfield Customer Review (What's this?)
 
Installed this on my '05 Altima SER with the Bose Premium Sound System with the SAT button and it works great. As I believe it was said before, you have to turn the sound up on your device so that it will be close to matching the same level of your radio/CDs. Sounds good, and was fairly easy to install.

The Crutchfield master sheet that comes with it does a very good job showing how to remove the head unit to install the device. I was a little confused at first with which plugs were which, because they looked very similar, but from what it looked like, the plugs on this device an only go in one place, so there's not a whole lot of confusion there. Good product. Would definitely recommend it.

2003 Pathfinder, Great Product!

Written By Upsyd0wn, Forest Grove, OR on Tuesday, April 14, 2009
Crutchfield Customer Review (What's this?)
 
I have a 2003 Nissan Pathfinder. It has the Bose stereo with RDS in the top right corner 6 disc changer built in with the tape deck on the bottom. It doesn't say if it is Satellite ready or not on the radio, but I bought the PAC AAI-NIS2 adapter and it plugged right into the back of the radio giving a WAY better sound quality then a FM tuner or tape adapter. After installed I just click on the radio button and two new things show up "SAT1" and "SAT2". There are two sets of RCA's that come with the adapter, I hooked my ipod plug up to the "SAT2". Worked great, I recommend it! (oh, Installation: The plastic vent assembly above the radio can be "gently" pulled out, I put a wide flathead screwdriver on the side and worked one side loose then did the same on the other. Once out you can see there are two phillips screws above the radio, remove these then gently pull around the outside of the rest of the plastic around the radio, it is just clipped in. Once that plastic is removed the radio is held in by 4 more phillips screws. The rest is just unplugging and plugging in things, should be easy to figure out!)

This product works very very well. I have this in my Infiniti G35 coupe 06 and it works perfect. This product has two rca's which is very important to me and both work perfectly. This coupled with the Bose stereo sounds amazing. I have this with a Sportster 5 sirius set and the difference between this and the direct FM adapter is completely different. The sound is perfectly clear and there is much more fidelity. I would definitely recommend this product to anyone not wanting to change there factory deck but still have the ability to hook rca's up to it

Works & Sounds Great

Written By yeti402, Sterling, VA on Friday, January 02, 2009
Crutchfield Customer Review (What's this?)
 
This device does what is described and sounds great in my 2005 Nissan Murano. As other reviews have noted, you will need to turn up the volume on the iPod to get the level you want, and once you do, its fantastic. The only complaints I have is that it does not charge the iPod battery, display music info (title, track, artist), or have any navigation control through the factory headunit; since this device acts as an AUX input. Otherwise, its a fantastic solution to have superb sound quality from your iPod in you SAT ready vehicle.

Finally...No Static!

Written By Dawn, Stafford, VA on Friday, July 11, 2008
Crutchfield Customer Review (What's this?)
 
I got a new Sirius receiver for Christmas and the signal strength for the wireless FM modulator was much lower than my previous receiver. I was getting so tired of all of the static. This adaptor works GREAT!! Not only do I have absolutely no static or interference on my satellite radio, but I can also now plug in my Zune and play it through my car stereo. Sure, I have to turn the radio volume up more to be able to hear it, but it works great and that is a small price to pay to not have to hear the annoying static anymore or pick up other people's satellite radio through my radio. It was fairly easy to install also. The box fits perfectly behind my nav screen.

Did not work.

Crutchfield Customer Review (What's this?)
 
I got this to
install in my 2006
Altima with a Bose
system. The install
was easy, the master
sheet was right on.
When I hit the SAT
button, all I got
was the SIRUS Radio
ID, no AUX input. I
called Tech Support,
he worked with me to
see where I went
wrong, but it would
not work.
Crutchfield was
great, they sent a
replacement next
day, but the same
results. Oh Well, I
guess I need to
replace the whole
radio.

Great Product - Nissan Murano 2007

Written By Dave, Gainesville, Fl. on Monday, March 31, 2008
Crutchfield Customer Review (What's this?)
 
As written in the previous reviews, this item was easy to install and works well with the factory stereo. I had to call for support for the panel removal necessary to remove the stereo. This was the only frustrating part of the whole endevor as it took me about 20 minutes to get through to someone. But they were very helpful and directed me appropriately.

The volume difference between the cd/fm and the sat radio is significant. You have to turn up the volume pretty hight to get a good response thus increasing the THD to more than I would like. That however does not even compare to the frustration of static from the fm transmitter.

Im running my Ipod and sat radio from this device and they both work fine. Definitely recommend

Works fine in an 2006 Infiniti FX35. Audio level is a little lower than normal radio or CD, but not by much.

PAC AAI-NIS2 Auxiliary Input Adapter

Written By erkishhorde, California on Wednesday, February 06, 2008
Crutchfield Customer Review (What's this?)
 
Keep in mind that this unit requires your vehicle to be satellite ready. My Frontier is not and the vehicle check by Crutchfield doesn't catch this. For some reason when I clicked the Installation details it didn't tell me anything about that so I bought it and ended up returning it when it didn't fit.

Props to Crutchfield for their great customer service.

Works great.

Written By Mike Mc., Philadelphia, PA on Tuesday, December 04, 2007
Crutchfield Customer Review (What's this?)
 
I was tired of poor FM reception from the modulators I have for my iPod, so I had to find some sort of direct connect option. My 2005 Nissan Pathfinder had the upgraded Bose system that sounds good, so I really did not want to go with a new receiver and try to integrate that into the system's speakers and sub-woofer. In research, I came across this device specifically for Nissan and Infinity factory radios. I have always trusted Crutchfield, so I placed my order.


The install is easy enough on the Pathfinder. You must pull out the cup holder trim, the gear case trim and the radio trim, but it is really easier than it sounds. I did not need any special tools, just a properly placed screwdriver for leverage and then one screw above the radio. Took less than 10 minutes. Then you can get the radio out which you must do to get at the connections on the back. Crutchfield's instructions are 100% accurate.


The wiring harness for this unit plugs into the back of the radio and the 2 inputs you have removed plug into the harness. Then you can put the radio back. The wiring is run down below the radio and the "black box" of this unit was placed under the radio out of the way.


I drilled 2 holes through the back of the recessed shelf in the trim below the radio to run the 2 RCA cables out to the interior. I then re-installed the trim and tried outr the unit. Alternatively, you can run the wires out from under the dash or even through the glove box if you want.


At first I only got sound out of the right speakers. I found that the connection between the wiring harness and the PAC box was not secure. A little pressing in resolved the issue and I got left and right.


The steering wheel controls work for audio source selection with SR CH 1 being the main niput and SR CH 2 being the second input directly on the box. The RADIO button cycles through FM, AM, CD and now SR. The A-B-C button while in SR mode switches between inputs CH 1 and CH 2. You can set presets for these, but SR CH 1 must be on the A presets and SR CH 2 must be on the B presets.


Sound quality was great. I did have the iPod volume at max to get the level similar to radio, but radio is a bit louder. That being said, there was no problem with not enough volume when driving.


2 inputs means you can connect an iPod and a Satellite plug & play unit at the same time so you do not have to switch cords while driving. And best of all no more FM static and reduced audio quality.


I recommend this highly. It works.

If your using an FM transmitter and your tired of all the annoying static (especially here in NYC) then this item is great. It's very easy to install. It takes about 30 minutes and the sound quality is awesome!
