Crutchfield Customer Review (What's this?)

This works just like it should. You plug it in to the Sony head unit and can play your MP3 player through the unit. There are no settings involved. Literally just plug and then plug your MP3 with a cable and then play your music. My unit is a Sony cdx-f5000.

Pros: Simple Effective Reasonable price compared to buying a new stereo.

Cons: None

Worked for me

Crutchfield Customer Review (What's this?)

Plugged it up to a XM ready CDX-CA705M in my boat and nothing happened. I soon realized that I put it in the wrong way and when I turned it around and snapped it in, switched the stereo to CD2, I became a happy man. Works great and I can now use stereo controls to control volume versus fighting with iPad or iPhone.

Sony PAC Unilink Adapter on a Sony DSX-S210X

Written By Jim R, Ridgecrest, CA on Tuesday, December 03, 2013

Crutchfield Customer Review (What's this?)

This was suggested by a Crutchfield Tech so I could add an XM radio or other source to the Buss RCA cables. After also reading the reviews here, I thought I would take a chance. It did add a CD player option, but nothing works on the Buss cables. After calling Sony, their tech told me that sometimes they will work and sometimes they won't....... He suggested I buy another stereo with an aux cable option.......Not what I wanted to hear!!

Pros: Unfortunately none

Cons: A wasted $30.!!

Easy, cheap, great sound, but often must reset

Written By Anonymous, Albuquerque, NM on Wednesday, January 09, 2013

Crutchfield Customer Review (What's this?)

Super easy to install. I installed it on a Sony CDX-MP30 unit, which is 11+ years old. It works as advertised, but I must reset the unit fairly often when I power it on in order for it to recognize the "CD2" input. This could be because of the ancient Sony unit. Would have given it 5 stars but for the reset issue. This is not a big deal. I just hit the rest button each time just before attaching the faceplate. Note that you must supply the audio cables from the head unit to your iPod, etc.

Pros: No brainer install. Way cheaper than a new head unit. Sound quality equal to playing CDs.

Cons: Often need to reset the head unit for it to recognize the connection to the iPod/iPhone.

Stupid Simple Solution

Written By Jaron, Utah on Tuesday, May 22, 2012

Crutchfield Customer Review (What's this?)

It just plain works. No special wiring or anything. Unlocks the BUS jacks for any RCA or 3.5mm hookup you want.

Pros: Simple solution. Plug in and that's it. Dead cheap. $30 is less than you'll spend on "quality" FM transmitters. Seems to have a lengthy backward compatibility list. Works on my old 2002 - 2003 CDX-MP40 unit.

Cons: As listed elsewhere, the display gets stuck to CD2 ( I can't even switch back to the clock. ) I'm not sure if that's a limitation of the adapter or the dash system so I won't dock any stars. Also the dongle will need some space of its own above/behind/below the head unit ( this may or may not be a problem with your particular vehicle. )

Failure after 3 months

Written By DP256, Charlottesville, VA on Monday, February 13, 2012

Crutchfield Customer Review (What's this?)

This product worked well for about 3 months then stopped working; should have noted the other reviews that stated the same. Typical of Sony, unilink does not play well with others. Trying the Sony XA-300 this time. Love Crutchfield! very much, their support on my last stereo install was above and beyond.

Pros: Cheaper, functional

Cons: Early failure of unit.

Works on old Sony CDX-5000x, with a catch

Written By ak, Lakehurst, NJ on Monday, January 16, 2012

Crutchfield Customer Review (What's this?)

I had an old Sony CDX-5000X with the Audio Bus in. The PAC unilink adputer was able to plug in, but I needed to clearance the strain relief with a grinder. It was very minor and was because the head unit had an indentation to put the plug in. Turning on the stereo I was able to select FM1, and then CD2 for the source list. The only catch is that if you also were playing a CD from the CD1 input and shut it down from that screen, you won't see the CD again. The only way to get it back is to remove power from the head unit, remove PAC adapter, then power head unit back on to remove CD. Then remove power, install PAC adapter again, and finally restore power. I expect some difficult with an old head unit and audio in, but at least it works if I follow my process of always returning to the FM1 source before shutting off the radio. It other wise works fine with my iPhone.

Pros: It works, simple to install, allows you to use Bus In on my old head unit.

Cons: Strain relief was too big for head unit, may render CD1 disabled if shut down head unit in wrong order.

It works great!

Awesome product! Does exactly what it is supposed to do.

Great product!

Crutchfield Customer Review (What's this?)

This product worked great on my Sony CDX-C7050X. Easy install. Just pushed Source and
then Mode to get it to go to CD2.

At one point, however, my head unit malfunctioned and I could not access any CD or CD
function. I removed my faceplate and reset it. Worked fine. Not sure if it was adapter or not.
Still highly recommend this.

PAC Unilink Adapter For Sony

Written By Matt, Bellevue, OH on Wednesday, September 01, 2010

Crutchfield Customer Review (What's this?)

The PAC Sony Unilink dongle is an excellent way to connect a portable MP3 player to an
older Sony head unit which lacks the auxiliary input of newer models. It works great with
my Sony Mobile ES CDX-CA860X, and enabled me to use the RCA inputs
originally intended for a CD changer.

Installation is simple and straightforward, however there were two things that I hadn't
expected - After installation, the head unit did not power on. After removing the faceplate
and pressing the reset button, everything returned to normal. Another unexpected
problem was that the CD2 input doesn't seem to be an available source if there is a CD
in the head unit. Ejecting the CD allows CD2 to return as an available source.

Crutchfield sales and support were top notch as always, with fast shipping and a good
price for this adapter.

Worth a shot

Crutchfield Customer Review (What's this?)

I purchased the PAC adapter in order to plug in a Sirius radio. The original adapter worked at first and then quit. I returned it for another one. The second adapter worked great for about a week and then quit. It started working again, however, I decided it was not worth the hassle of not knowing when it will work.
I love the concept of allowing the aux. plugs in the back. I may have just had bad luck with this product. It may work for you. I have decided to stay with the FM transmitter. The sound quality is much better with the PAC, but as I said, mine wouldn't work consistantly. Best of luck to you.

So far, so good.

Crutchfield Customer Review (What's this?)

I was searching for options for adding an auxiliary input to my Jeep for an external XM radio and Ipod at times. I have previously used a hard wired FM modulator and liked the performance with it but it was big and required wiring and an external (to the radio) control box that plugs inline with the antenna. So, I wanted something a little simpler with great sound. I have an old Sony CDX-M600 radio that was going into the Jeep because I like it and it still works very well. I stumbled upon this product and figured what the heck, I can try it and see if it works and if it don't then I can return it. Let's just say I won't be returning it.

I haven't had a lot of time to fiddle with it but I got my head unit installed (the Sony) and plugged the patch cord into the audio inputs on the back of the unit. With my Ipod plugged into the patch cable, the miracle of sound came out of the stereo playing my favorite tunes. All I had to do is navigate to CD2 with the source button and there it was. The adapter fools the head unit into thinking there is a changer plugged in so it makes up track numbers and disk numbers somehow.

Bottom line is it works and works well, I am glad I found it and tried it.

On a side note, the compatibility list does not include my specific Sony head unit as being compatible. If your head unit is not listed you may have to just buy it and try it like I did to see if it will work. You will not be disappointed.

A GREAT little device!

Crutchfield Customer Review (What's this?)

I drive a 94 Isuzu Trooper with a Sony XR-CA350X deck in it, and wanted a way to play my MP3 through my stereo without replacing the head unit. This adapter activated the RCA inputs in the rear and allowed me to use a 3.5mm to RCA cable to play the audio from my MP3! It is dead simple and fit great. The sound quality is that like ONLY a hard-wire connection can offer.

The website said that this wasn't compatible with my deck, but it works perfectly. My advice to those who are put off by the fact that the website says it won't work is this: if you have RCA inputs labeled "Bus audio in" and a din connection on your SONY deck, this will most likely work for you. Just make sure that you have the space (the cable isn't LARGE, but sometimes it gets a little cramped back there) behind your deck!

Works Perfectly

Crutchfield Customer Review (What's this?)

I have a Sony CDX-C5050X receiver and the Unilink adapter works perfectly. I had been searching the internet far and wide for a way to hook up my mp3 player without using a stupid FM transmitter. This is the only item I found that would work for my Sony Stereo, and it's $100 cheaper than most other options.

Worked on the CDX-C90

Written By Sean, Missouri on Tuesday, March 18, 2008

Crutchfield Customer Review (What's this?)

Worked fine on the Sony CDX-C90. I hit the mode button and it came up as CD2.

I only had one complaint about the adapter. When you connect the right angle connector to the C90, the dongle goes up. Its flexible enough to not be an issue for me, but it might be for someone else.

Great Product!

This product extended the life of my Sony receiver. I was about to buy a new receiver with an AUX input so I could listen to my MP3 player, but the PAC Sony Unilink adapter kept me from having to do so.

Just a word of caution. This product caused my Sony MEX-BT5000 to constantly reboot or cycle power. Since I have taken it off the problem has gone away. You would think Sony products would be compatible... go figure.

Crutchfield Customer Review (What's this?)

Sweet!!! This device saved me hundreds of dollars!! I've been on a quest to "directly" hook my i-pod into my 3 year old marine stereo system. I've hit dead end, after dead end, with the so called experts. up until now!! This small plug "turns on" (activates) the RCA input jacks on my unit's rear panel (they are dead without it). No more listening to tunes via the flunky FM transmitter route. This direct hook up is THE WAY to go.
I also had a great experience in dealing with the Crutchfield team (first time). They were very knowledgeable and helpful!! My order even got here a day earlier than expected!! Thank you soooooo much!!

PAC Sony Unilink adapter

Written By Ballpython, Overland Park Kansas on Thursday, December 14, 2006

Crutchfield Customer Review (What's this?)

I bought this for my cdx-ca700 CD player so i could use my iPod in my car. Every other adapter i found was at least $75 or more. This allowed me to use the Auxiliary inputs on the back of the deck so i would not have to use another FM modulator or buy another radio. I had to modify the connector so it was not at a right angle. It would not work due to an extremely tight fit preventing a good connection. I just removed the plastic houseing around the plug, straightened the connector, and taped it with electrical tape. now it works perfectly every time i listen to my iPod

PAC Unilink Adapter For Sony

Written By John, St. Petersburg, FL on Saturday, November 18, 2006

Crutchfield Customer Review (What's this?)

I was wanting to play my music from my MP3 player through my Sony's Aux Input but everyone was telling me that I would need to buy more stuff from Sony to make them work. (It says AUX IN on the box but you have to pay them more money to use it.) Instead I bought this from PAC and it does exactly what I wanted. I recently bought an iPod and I'm using it for that now without having to buy anymore stuff from Sony to use it with my receiver. That is when I realized that I can use any audio device (i.e. DVD player, other MP3 player, MiniDisc player, or even my guitar) in my car without needing to buy anymore stuff from Sony or anyother company.

The one and only problem that I have with it is that I can't view the clock when it is on CD2 even though it is showing fake CD tracks times. This bugs me because I tend to be late to work a lot. I can deal with this by wearing a watch.

I thought it was awesome that you didn't have to pay the $100 for the XA 300, so it's pretty much a cheaper alternative to the XA 300 as long as all you wanna do is hook up your mp3 player.

Great option to the expensive XA-300

Written By wrxdude144, Philly area on Friday, August 04, 2006

Crutchfield Customer Review (What's this?)

Last year I got a satellite radio to hook up to my 2000 vintage Sony ES stereo. I quickly found out that the aux inputs were not what they seemed to be. And I also found out that Sony's 'solution' to the problem they created, the XA-300, would set me back $100.00.

After putting off purchasing the Sony XA-300, I found a reference to the PAC aux input adaptor through an internet search. The link brought me to the Cruthfield product page, where I found the solution I was looking for, for $30.00.

I purchased the PAC adaptor, and in two days Crutchfield had it delivered to my door. The adaptor is a plug on one end, and a short cord terminated by a small plastic piece. The adaptor plugs into the CD changer input on the back of the Sony unit. Installation took me all of 30 minutes, including taking out and reinstalling the stereo (I already had the satellite radio hooked into the aux input.) The most difficult part of installation was figuring which way to plug in the adaptor.

I put everything back together, and turned on the head unit. I pressed the Source button to switch to CD, then pressed the Mode button to switch to my satellite radio. It came on as expected, showing up as CD2. Track and time info were also being displayed, which of course is meaningless with satellite as the input. But still, it works great, and makes a huge impact on the sound I get from satellite.

Sure, the XA-300 gives you two aux inputs, a USB connector, and headphone output. But all I wanted was to hook something up to my Sony aux inputs, and the PAC does that just great.

Hands-on research

What's in the box?

Download owner's manual

  • AUXON-SONY 5.75" right angle Unilink adapter cable

Product Research


Overview: This cable makes it appear that a CD changer is connected to the Unilink connection on a Sony head unit with CD changer controls. By making it appear that a CD changer is connected to the Unilink input, the audio from an auxiliary source, such as a portable MP3 player, can be fed into the BUS AUDIO RCA inputs of the head unit. If your Sony head unit has the Aux Lite feature, this adapter isn't needed to input audio from an auxiliary audio source. When this adapter is used, a Sony CD changer cannot be connected to the head unit.

Compatibility: Compatible with Sony UniLink head-units that are changer controllers that use a DIN cable as well as RCA inputs for its CD changer connections. For proper functionality, the head unit must also be "Sat Ready" and support scrolling text.

Connections: The right angle Unilink connector simply plugs into the CD changer data port on the back of a compatible Sony head unit.

Note: One end of the adapter is terminated with a right angle Unilink connector, and the other end is terminated with a small box with circuitry that allows the BUS AUDIO RCA connections to be used as an AUX input.
