Crutchfield Customer Review (What's this?)

Make sure you hook up the blue wire to the blue remote wire coming out of your radio. If you do not hook power up to the blue wire your reception will be awful. The instructions are poor and do not tell you to hook it up. I had to search the Internet and find that indeed you needed the blue wire connected to the remote wire in order to get a good signal.

Pros: Great product

Cons: Poor instructions

Pros: Easy to hook up

Cons: Not clear directions about whether the blue wire needed connecting but tech support call cleared that up...it does need to be connected.

2010 Nissan Altima
Crutchfield Customer Review (What's this?)

In the Q&A on 14/Mar/14, David asked a legit question about the blue wire function. The reply by Crutchfield was totally useless. I had to research myself. Simply enough the blue wire connects to a switched +12vdc via the stereo. This powers the factory Nissan antenna amp. Without this connection, the factory antenna is almost useless. Why this couldn't be directly addressed by Crutchfield is beyond me.

Pros: Unit works well when properly connected.

Cons: Instructions suck

You gotta have it...

It fit my 2012 Altima perfectly, and does exactly what it's supposed to do. Quality product. Note: don't forget to hook up the blue wire to the remote turn on output wire from your stereo. The Altima has a powered antenna and needs this to function properly.

Pros: Quality product, perfect fit.

Cons: None.

Hook it up right

David from Texas on 8/6/2015

2013 Nissan Altima
Crutchfield Customer Review (What's this?)

It works now that I have it hooked up right. Initially I did not have the blue wire of the harness attached to the blue/white trigger wire from the radio, this acts as the antenna boost signal. Initially had pretty poor reception. Crutchfield tech support pointed out the error when I called and I changed it around. Sounds great now. Its nice having people to bounce questions off of.

Pros: works well

Cons: wire color doesn't match required vehicle wire

My kenwood unit would not pick up a channel until I hooked the blue wire to an excess power wire coming off the unit. There wasn't much in the way of directions with this, but I hooked it to the power antennae wire(think you could use amp on wire too) and it gives me more stations than I ever could find with factory antennae.

DallanC from Utah on 3/31/2015

2014 Nissan Rogue Select
Crutchfield Customer Review (What's this?)

Giving this only 4 stars as instructions do not state you need to run power through the blue wire. It took me some time googling to figure this out. Reception is terrible until you power the antenna receiver. Beyond that, its a super simple connection to a head unit.

Pros: Extremely easy connection to head units

Cons: Instructions don't state to connect power through the blue wire. This must be done to power the antenna amplifier otherwise your reception will be terrible.

Perfect fit

Necessary, but you need to know that you have to wire the blue wire in a 2009 Nissan Versa to the remote or Aux cable. You need the 12VDC for the Antenna amplifier.

Pros: important cable.

Cons: No instructions.

Crutchfield Customer Review (What's this?)

It's a clever product, but it does not have instructions. I thought the blue wire was for a motorized antenna (which I don't have). So when I installed the head unit I had no reception. I went on you tube to find out that the blue wire has to be connected to a power source.

Pros:

Cons: Needs instructions explaining the blue wire

This installed perfectly, but be sure to cap the blue wire if your antenna is not powered. The factory cut is good but I put a cap on mine just to be sure there isn't any loose copper with the rest of the wiring.

Good antenna adapter for my Nissan Versa's car's antenna connector to my Pioneer SHA-DA120 AppRadio 4 head unit. Easy to install, simply plugs into the car's OEM connector and the other end plugs into the radio.

Pros: Makes adapting replacement radio to wiring harness easy.

Cons: There is a blue wire that needs to be connected to the car radio's aux antenna or amp power circuit, which is blue/white. The instructions, which are supplied with the package do not indicate this.

I installed the Kenwood DPX500BT stereo from Crutchfield in my '09 Nissan Versa base sedan,got the antenna adapter free. Crutchfield techs told me that the blue wire goes to the antenna power wire on my radio because the Versa OEM stubby antenna has a signal booster that has to have 12 volts applied to it to be able to receive radio stations clearly.

This is a very solid built cable. The only issue I had was that there were no instructions stating to crimp the blue wire into the harness (matching the "Accessory" cable). The radio will still work but the reception is almost non-existent. Don't forget to do this like I did. Not worth taking a star off for my own stupidity though.

Pros: Quality built cable

Joe from Arcadia, FL on 2/1/2013

2009 Nissan Versa
Crutchfield Customer Review (What's this?)

After I installed my head unit, I noticed that my radio reception was terrible. I neglected to connect the blue wire to the remote turn on wire, I figured I didn't need to because my antenna is not motorized. YOU CANNOT skip the blue wire. You must attach it to your head unit on either the blue/white remote turn on lead or the blue accessory lead. Without doing that, your reception will be terrible (but will work) and may make you think it's your radio or speakers. No idea how it fixes it, but it seems to be a common issue with the Nissan antennas/adapters. Coupled with the new HU, it makes a huge improvement in existing reception over the old HU."

2008 Nissan Xterra
Crutchfield Customer Review (What's this?)

This adapter fit our 2008 Nissan Xterra perfectly. We did not connect the blue wire to anything though, because I don't think it's necessary. FM radio works fine, we haven't tried AM.

Pros:

Cons:

Worked as advertised

AlanJ from Florida on 6/16/2012

2010 Nissan Altima
Crutchfield Customer Review (What's this?)

Matched the 2010 Altima's factory antenna connector and the radio plug-in connector exactly. Don't have a power antenna, so the blue wire wasn't needed (just taped it closed).

Pros: Exact fit.

Cons: none.

Just connect the blue wire to the matching wire on your radio, plug the Motorola connector into the radio and the vehicle antenna lead into the matching adapter connector and you are done!

Frontier 2008 CC 4 AW

Walter W from Colorado Springs on 4/15/2012

2008 Nissan Frontier
Crutchfield Customer Review (What's this?)

Excellent product. The blue wire is necessary to supposedly help boost reception in our 2008 Nissan Frontier. The blue wire on the antenna adapter can be attached to the "remote turn on" or "amp turn on" wire on the new radio. In this case the AVH2400BT Pioneer HU had a blue/white stripe wire labeled "remote turn on".

Pros: A must have to attach to the Nissan antenna.

Cons: The only problem is being sure what to do with the "blue wire". Crutchfield had the answer.

Works like a charm!!!!!!

Crutchfield Customer Review (What's this?)

Be sure to connect the blue wire for Nissian Altima. I used to amp turn on lead and it worked much better. Without the connection of the blue wire it did not work - static.

Pros: easy and cheep

Cons: requires research to find what wire to connect the blue lead

Good antenna adapter

2008 Nissan Versa
Crutchfield Customer Review (What's this?)

This works great, just make sure that you are attaching it to the correct wire that is on the wire harness for you car. I have a nissan versa and I figured that because the wire was blue, that I would attach it to the corresponding wire. I then got nothing but static. I called up tech support and they were great and informed me that it needs to connect to the blue wire with the white stripe on it.

2009 Versa

Old Guy from Leesburg, VA on 8/14/2009

2009 Nissan Versa
Crutchfield Customer Review (What's this?)

Works fine. The Versa has an amplified antenna. The blue wire needs 12 volt power (switched) from the radio. A master sheet for the Versa with this information would make this a 5 star rating.

Pros:

Cons:

Fits perfectly, but WARNING!!

Ronald from Fort Wayne, Indiana on 4/12/2009

2007 Nissan Versa
Crutchfield Customer Review (What's this?)

Fits my '07 Versa perfectly, but make sure you connect the blue wire to the power antenna/remote control wire from your head unit. Otherwise you will get poor reception. I speculate that there is some sort of a preamp connected to the car antenna that requires the power.

Pros:

Cons:

Does not FIT on 08 Altima 2.5S

Flavaj78 from San Jose, CA on 3/26/2009

2007 Nissan Altima
Crutchfield Customer Review (What's this?)

Mine did not fit. I ended up not using the harness at all. I just used the antenna connection inside the harness and that ended up fitting to my OEM antenna wire. I also spliced the 'Power Antenna' wire to the OEM Radio wire.

Crutchfield Customer Review (What's this?)

Much like a previous reviewer I too had a faulty adapter sent to me with my DNX5120. After contacting Crutchfield they sent out a replacement and the 2nd one worked perfectly. The adapter is very cheaply made so it is hit or miss at best.

Edward from Southern Alabama on 1/28/2009

2008 Nissan Pathfinder
Crutchfield Customer Review (What's this?)

This adapter was sent by Crutchfield used to connect a new Kenwood headunit to my 2008 Nissan Pathfinder. Once all installed I had problems with the radio reception. Reception was very weak and almost not at all. First thought was the problem was within the head unit. But after a call to Crutchfield tech support, we were able to determine the problem was not the Kenwood unit. Crutchfield sent out a new adapter. After installing the new adapter, the problem was resolved. Reception was restored. Maybe I just got a faulty adapter.

Pros:

Cons:

Doesn't FiT

Frederick from Bensalem, PA on 7/31/2008

Crutchfield Customer Review (What's this?)

The female antenna adapter socket did not mate with the male Nissan Antenna connector. I had to "Push" the antenna coaxial connector through the shell and connect to the nissan male connector "outside of the shell and then put tape aound the connection to hold it together. Also had to connect the switched power from the receiver directly to the nissan cable line which powers the Nissan antenna amplifier since I was not using the connector shell of the adapter. Over all a poor fitting adapter, but without it you cannot make the antenna connection.

Cons:

Needed this "power" adapter for my Nissan Altima. I'm "old school" so when I saw the "power antenna" lead on the adapter I didn't think I needed to hook it up because to me a "power antenna" pops up when you turn on the am/fm radio. But it must be hooked up because the Altima has a "powered antenna". So make sure you hook up the lead! [ Tim E.  Jan 31, 2016 ]
