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.

Written By Steve, San Diego, CA on Sunday, July 21, 2013

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.

Pros: Works

Cons: 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.

Pros: Works, connects easily, does what it is supposed to

Cons: Motorola connector not as tight as desired. A short strip of electrical tape makes sure it won't work loose

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

Written By JV, San Jose, CA on Thursday, January 10, 2013

Crutchfield Customer Review (What's this?)

it connected fine. from some of the reviews below I guess I can't complain. I've always heard that reception is diminished with aftermarket decks but wow. A lot of the stations are now almost inaudible. But then again the particular stereo purchased was not for it's radio awesomeness.

Pros: connects and works as advertised

Cons: 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

needed this. perfect

This was perfect for installing my new radio and the one I had was to short to allow the radio to come out further. Plus this was free when I purchased my Receiver.

Written By rbkrazy, Irving, TX on Thursday, April 05, 2012

Crutchfield Customer Review (What's this?)

Plugged in and worked as it should. I didn't give it 5 stars because the retainer clip that prevents it from becoming unplugged did not fit perfectly. It does not affect the function of the adapter at all. Mine is plugged in and working great. I would buy it again.

Pros: Cheap, easy

Cons: retainer clip not perfect

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.

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.
