Used when replacing stock Bose stereo in my Maxima. You will need it! Plug in ease of install. A little bulky, I had a lot of wiring behind my stereo to push back in and this antenna wire is pretty thick. Has a secondary port for adding other equipment... which I didnt need.
Pros:
Works as it should
Cons:
Didn't need second port... maybe should be an option for less wires.

Crutchfield Customer Review (What's this?)
 
What can I say? It works and you need it to adapt Nissan's weird two-pin connector to a standard antenna plug. Would've liked it to be a little shorter as there wasn't a whole lot of room left behind the stereo with the wiring kit installed.

Works

Longer than necessary, IMO

What can be said. the adapter works, connects properly to the Aftermarket stereo and the Bose Dual antenna connector in the Pathfinder. It is just what is needed.

Bose Nissan antenna adaptor

Written By Uncle Willie, Thomasville, GA on Wednesday, March 13, 2013
Crutchfield Customer Review (What's this?)
 
The Nissan Bose installation uses a two wire antenna lead on the factory radio. The actual antennas are in the glass of the rear window of a Maxima. When hooked up with the flanges aligned, the radio got poor FM reception and no AM stations. I read a review on this site about reversing the connection, so I tried that, and now the FM works great and AM is unchanged. It's anybody's guess how the factory wires these antennas, and the Bose radio that was in my car has a Clarion label on it, but it was the very finest FM radio I've ever used. I never would have replaced it if it had an USB input so I could use my iPod. The new radio is a JVC KW-NT500HDT.
Pros:
It works, but it's not intuitive how to connect it.
Cons:
Ambiguous instructions

reception diminished, might not be the adapter's fault but....

It wired BACKWARDS

Written By ChrisZeeshutterbug, Louisiana on Wednesday, January 02, 2013
Crutchfield Customer Review (What's this?)
 
After hooking up the stereo, and the antenna (with the adapter clip oriented properly) I got zero AM stations by scanning and one by manual tuning. OK, so I heard most aftermarket stereos are poor on AM. On FM all of the regular stations came in on scan fine, but no weaker stations at all. I drove around a few days like that, but after a second thought I did more reserch on the receiver and the antenna adapter. On on site I found a person who swore that thw antenna adapter on Nissans is wired backwards and works much better in reverse. OK, I was good at taking the dash apart now, so I went for it. it IS TRUE!. When the adapter is put in with the clip on the smooth side (backwards) I get 6 AM stations (still none on scan) and EVERY FM dial position has a station on it (with scan)!
Pros:
Works well when plugged in backwards
Cons:
Wired bacwards

Doesn't work on Pathfinder

Written By clayr, wilmington, nc on Tuesday, January 31, 2012
Crutchfield Customer Review (What's this?)
 
The product is fine performance-wise, but the description should include that it will not work on a Nissan Pathfinder. There is a metal heating duct (or a brace-not sure) behind the radio unit, which is bypassed by the stock antennae cable's L-shaped design. This adapter cable, when plugged into the radio, does not allow the radio to fully seat into its proper place. You will need an L-shaped connector for the pathfinder.
Pros:
other than the design issue, it works fine!
Cons:
Does not fit 2007 model Pathfinder.

Why the extra lead?

Written By Steve M., Phoenix, AZ on Saturday, July 02, 2011
Crutchfield Customer Review (What's this?)
 
This adapter worked fine for connecting the new Kenwood KDC-348U to Infiniti's proprietary antenna connector, but I have to wonder why they had to provide both male and female radio-end connectors. Yes, I know, some aftermarket radios have male leads, some have female; but, this configuration makes it just a bit harder to find enough room under the dash. I zip-tied the whole thing together to shortened the overall length and to keep that extra lead from just flopping around. A lot of extra wire and hardware just to avoid having to inventory 2 different adapters - I would design this with a single, male end- connector for the radio and provide a female-female sleeve for those radios that have a male-end antenna connection.

Crutchfield Customer Review (What's this?)
 
This was probably needed on some higher end models. Did not use because it was not needed on my 1995 Nissan Truck.

I bought this for an '03 Maxima with the Bose system. It works. Buy it. Not much else to say.

It fits and works well the only thing I dont like is the extra adapter ( takes up too much space) other than that no complain.

Crutchfield Customer Review (What's this?)
 
I recently used this to connect the factory antenna on my 1997 Nissan Maxima up to a Clarion replacement deck. Worked well with no issues and antenna operation/station capture is good.

Reception is horrible. I saw another review on here saying to flip the connector around and it should pick up better reception,....it worked but only gave me one extra station so.now I only can get 4 stations in the heart of Phoenix. Any ideas how to fix this? [ Andy  Apr 19, 2014 ]
