Crutchfield Customer Review (What's this?)

Grabbed this little guy about a week ago and just installed it. Crutchfield sent a very nice instruction set specifically for my '01 Camry and that made the install that much quicker. In about 15min's it was installed and 15min later it was tucked away neatly with easy access to the inputs wheneven I need to make a change. Quality is what your source is but the XM sounds pretty good, better than my cassette adapter did and much cleaner to look at. If your considering an external audio source for your Toyota then go for this. It's easy to install and makes life a little cleaner and easier when using external audio devices.

Love it

Crutchfield Customer Review (What's this?)

Having purchased at 2006 Toyota Tundra and having Sirius sat radio, I did not want to replace my manufacture radio. Purchasing the USA spec was a great choice as the sound quality dramatically increased. I am very satisifed and am pleased at the customer service and quality of product that Cruchfield provided.

The directions included were easy to follow even for someone techincally challenged like me. It only took me about an hour to install, primarily because I spent time hiding my Sirius reciever wires behind the radio.

I highly reccomend this product.

15 minute install

Written By Duncan, San AntonioTexas on Thursday, June 14, 2007

Crutchfield Customer Review (What's this?)

It took longer trying to figure where the cable went into the back of the radio than it took to take apart and put together everything! Crutchfields instructions are first class, USA SPEC could learn as theirs are somewhat vague to say the least. I can see where others have had problems.
The steering column controls work like a charm. I would have been upset if I had lost them!

Toyota Tundra '04

Written By Jeff, CA on Thursday, May 31, 2007

Crutchfield Customer Review (What's this?)

I installed this on my Tundra yesterday. Took me about an hour. I was a little afraid to "pry" the dash unit off once the screws had been removed, but a little gentle work with a screwdriver did the trick. Start at the top and work your way around (like removing a bike tire).

The kit plugged directly into the back of the factory JBL 6 disk. I ran the cable into the glove box where the unit is located, and then a headphone to RCA cord back through the dash down to the ash tray. Just pop it out and feed it through a gap on the right front side. Then just pop the tray back in. Voila... totally Pro!!

By doing this, I can store the cord inside the ash tray when not in use (Totally hidden from view) and the cord just disapears into the dash without having to drill any holes. The ash tray can still close with the cord in use as well.

As stated in previous posts, no lost disk slots. Just press CD again to toggle between the Aux and disks. Steering wheel controls still work as well.

I installed this on my 2007 Toyota Tacoma. I replaced the FM modulator with this direct connection. The sound is much better, near CD quality. I definitely recommend this product for any applicable installation.

This purchase from Crutchfield was easy. I will make my next electronics purchase from Crutchfield.

Woks great

Written By stumpjumper, Albuquerque, NM on Tuesday, May 08, 2007

Bought this unit for my 2001 Honda Odyssey. Followed the Crutchfield directions and had it in in no time. Works just as advertised and sounds great. While messing with the cables during installation, I did run into a problem where the radio stopped recognizing the aux. interface. I pulled and put back in the fuse to the radio and that solved the problem.

Works great with ipod, not so great with roady xt

Written By Chilichad, Watertown, SD on Tuesday, May 01, 2007

Crutchfield Customer Review (What's this?)

By reading all the positive reviews I new this would work great with my 2005 Tacoma W/ JBL system.. The installation instructions were a piece of cake. I was done in 25 minutes.. I used the monster cable for both inputs for which I use a mini ipod and a xm roady xt. The ipod sound was crisp and clear. The roady xt really had a loud hissing sound that could not be fixed. Sounded better through FM transmitter. I do believe its a roady xt issue. Tried my old roady 2 and the hissing was gone. Luckily I live where there is no bleed over through the fm transmitter. Overall happy with the product...

A Few Answers For Highlander Owners w/ JBL Changer

Written By Don, Lincoln, NE on Sunday, April 22, 2007

Crutchfield Customer Review (What's this?)

I spent quite a bit of time reading the other reviews on both this product, and the USA Spec iPod adapters. There seemed to be a bit of confusion as to what to expect with the six-disc in dash factory JBL system (non-navigation). That is what is in my 2005 Highlander, and it carries the model number "A56382" in small gold letters near the top of the units face - in case this one comes in other Toyotas. The USA Spec Auxiliary Interface comes with a harness that plugs directly into the back of this radio, and fits perfect - nothing to unplug, just an unused square socket, ready for the plug! That harness then plugs into a longer cable that you can run where you like to mount the small box. In this application, there is another plug on the small harness that is not used, and there is plenty of room behind the radio for this other spare plug. I used a cable tie to gather things up a bit, and prevent it from rattling. I then mounted the box with double stick tape under the console, and added a 3 foot RCA to mini-jack cable. Very tidy, and completly hidden. The unit performs fine, and sound quality is as good as playing a CD. The volume level seems comparable, nothing at all like an FM modulator. The steering wheel volume controls work. I was under the impression from some reviews that you would lose one of your cds, that is, CD number six on the changer would now be the iPod, but that is not the case. You hit the "Disc" button, and it says "CD1", and that is the iPod. You hit the disc button again, and the "CD1" changes to "CD", and you are back with your regular changer. It's totally slick, and priced right!

Works Very Well...But Not w/ Roady XT

Written By Nick, Houston, TX on Tuesday, April 17, 2007

Crutchfield Customer Review (What's this?)

I just got this today, read three DIY your articles on how to remove the head unit and got this installed in my 2006 Tacoma Double Cab w/ non-JBL 6 Disc Changer (yes, it worked fine, the radio will say "Disc 1" when it is in aux mode, press disc again and it goes back to the sixth disc) When removing the climate control, be careful if you pry it back w/ a screwdriver b/c there is some clear plastic back there that just snapped and broke apart when I did that, but it didn't seem to be crucial as everything works fine. One thing I wanted to say was that with the Roady XT wired into this there was a lot of hissing noise. I went and grabbed my old Roady 2, plugged that in and the hissing noise was gone and the audio was 10x clearer. So be warned if you're trying to use a Roady XT, I think it has something to do with the base all the wires plug into, must be causing some noise/distortion. I also plugged my PSP in and it sounded fine although the bass didn't come through as loud or thumping as w/ a cd, but perhaps b/c the PSP doesn't have eq options. This is a good product and super easy to install!!

Works perfectly in my 2006 Toyota Tacoma Double Cab

Written By Jason, Modesto, CA on Monday, March 26, 2007

Crutchfield Customer Review (What's this?)

Dispite what the owners manual states, you can use all 6 discs in your 6 disk factory cd changer. Included is an adapter that lets you plug the Auxiliary Interface into the one remaining plug in the back of the radio. Crutchfield also includes a very detailed and long instruction manual. The good news is that the instruction manual is how to get into and replace almost anything in the cab of the truck (dash, doors, etc.) All you need for this project is the first page of instructions (page 2 I believe). Literally took about 15 to 20 minutes, but I had the radio out in less than 5. Here are some pointers:
When you are instructed to remove the Climate Control (doesnt say how though), pull off the left fan control knob and set aside. Insert a flat screwdriver in the opening and place the flat side on the back of the Climate Control unit and pull out. Then follow the next directions as written. I just set aside the radio, still plugged in. I ran the Auxiliary Interface cord down to the passenger side where your feet go. This can be tricky, but much easier if you unhook the "piston" that controls the opening of the glove compartment, thus allowing you to open the glove compartment farther then intended. That gives you easy access to reach up to where the radio opening is and pull the Auxiliary Interface cord down. Then reinstall the radio. Two last bits of advice. One is that the directions call for you to test it before reinstalling the radio. That meant I had to hook up the battery which then caused the alarm to go off. Also, it is difficult to rehook the "piston" on the glove compartment, so procede with caution. My MP3 sounds great!

DF-TOY Shuts Down Randomly on 2006 Corolla

Written By Frank, Saddle Brook,NJ on Friday, March 23, 2007

I installed the DF-TOY Auxiliary pre amp about a week ago. When it works, it works well. However, it randomly shuts down the CD input and switches over to the radio sometimes. Sometimes, it shuts the radio off all together and I have to shut the car off and turn the car back on again to get the radio working again. Then, everything works perfectly again, for a while. I never know when it will fail because it happens at random times. Crutchfield has been great as far as customer service. They are sending me out another unit. I hope this new unit work because I like the product but I can't deal with the problem of having it shut down randomly. I'm also not looking forward to taking my dashboard apart again.

Excellent Product 2006 DC Tacoma

Written By chris, Las Vegas on Saturday, March 03, 2007

I bought this for my 2006 Double Cab Tacoma to add connections to my Garmin Nuvi 660 Navagation and Sirius Satalite radio. This products plugs right into the factory head unit and allows you to switch between inputs with the track up/down buttons. Sound is perfect with no noise. The steering wheel audio controls are not affected and work perfect.

The Best Addition to your Factory Radio

Crutchfield Customer Review (What's this?)

I have a 2001 Toyota Highlander with {JBL} 6 disc factory radio. Took me 20 min tops to install. This product works awesome, you just press the CD button on your radio and it uses the 6th disc position, you still have 5 disc left plus if you are like me the thousands of songs from your I-Pod or other mp3 player. Plus you have a 2nd AUX for your XM-Radio or other product you might have. As I said before it works awesome with mine.

Crutchfield Customer Review (What's this?)

i bought this for my girlfriends 2003 camry xle with the jbl 6 disc in dash changer. the installation was a breeze with the instructions from crutchfield. 2 panels came off to expose the bolts for the stereo unit. after unbolting it, the auxiliary interface plugged into the slot for the external cd changer. before putting everything back together, i turned the car on to test it and by going to disc 6 on cd, track 1 is input 1 and track 2 is input 2. you only loose use of disc 6, discs 1-5 work just like before the interface was installed. great sound quality, make sure that your ipod's sound is turned all the way up. i drilled a hole into the center organizer for the y-cable to run through. there was enough room in the dash for the interface to sit freely without screwing it down anywhere. when we are not using it, the cord tucks into the hole out of sight. the entire install took 30 minutes (i am pretty handy though). i went with this option for her ipod instead of an ipod specific one because of the 2 inputs. now we can also use it for a portable dvd player or laptop, anything with a headphone jack. great product!

Works Well, Easy Install in 05 Corolla CE

DF-TOY does work with 2006 Factory Radio with built-in 6 disc Changer

Written By Greg, New Jersey on Saturday, November 04, 2006

The product works 100% as advertized. I have a 2006 Tundra with a factory radio that has a 6 disc changer built into it (non-JBL model). Using the supplied CAS-TA and CAS-TYi cables everything plugged together without problem. On the back of the radio the CAS-TA cable plugged right into the open connector for an extra external CD changer.

Upon pressing the radio's CD button I am able to play any and all of the 6 CDs loaded in the radio using the radio's disc selector button. Pressing the radio's CD button once more causes the radio's LCD display to now read CD1 instead of CD. The display shows Disk 6 - Track 1, which is AUX 1, as playing. Pressing the track selector causes Disk 6 - Track 2 which is AUX 2 to play. Pressing the radio's CD button again causes the LCD display to revert back to CD. Whatever CD and track was previously playing starts playing again, right in mid-song.

Others have stated that the sound level from an iPod using the iPod's earphone output and the DF-TOY's AUX input is not very loud. I found this NOT to be true. In my factory radio, the volume level from my Nano is just as loud as that from a CD.

Hope this helped people on the fence. The sound quality is fantastic and Crutchfield's 100% refund policy makes it a no risk decision.

Outstanding Product

Written By Gary, Marysville, WA on Sunday, October 01, 2006

I purchased this along with a Sirius Starmate ST2. The install steps very exact to my car (I have a 2007 Toyota Corolla S). 1 screw and 4 bolts later I had everything out that I needed. The unit plugged directy into my factory 6-Disc changer and everything is functional.
I have my Ipod and the Starmate hooked up together and can use everything.
On the Toyota stereo, input #1 is set to Disc 6, Track 1, and input #2 is set to Disc 6, Track 2. You do lose one disc, but when you have satellite radio and a stereo, it seems a waste to have the 6 Disc changer.
Thanks to Crutchfield for detailed instructions with pictures! Overall a great product and the sound is leaps and bounds better than any FM transmitter.

USA SPEC Auxiliary Interface

Written By Fritz, Marin County, Calif on Monday, September 11, 2006

Crutchfield Customer Review (What's this?)

Near-perfect experience installing on a Scion xA with exemplary documentation and telephone support from Crutchfield. The only glitch, not major, was getting the front panel alligned and back on, but I don't exactly do a lot of this. I found that if I unscrewed the Scion's translucent storage compartment below the radio, I could easily run the cable down to the ashtray, remove the ashtray itself, and wedge the unit's metal case in the slot from behind. A convenient place to plug in. One thing to note: the Scion radio "thinks" the unit is a CD changer. So if you play an actual CD in the actual player, the unit isn't recognized.

This is awesome

I am kind of guy who goes to toyota dealer even for a oil change.I was searching for an aux interface for my iRiver and found this one. It took about 1:30 hours to install on my 2000 Celica GT, and when I turned it on the quality was unbeleivable.

I didn't expect such an increase in quality. Highly recommended. It could be my iRiver,my factory speakers produces so much bass,that I have to sell my JL amp & Subwoofer.
Installation guide from Crutchfield was excellent.Just follow it step by step.

USA SPEC Auxiliary Interface

Crutchfield Customer Review (What's this?)

Exceptional piece of equipment. I did not know there was such a product available on the market until I came to Crutchfield. Don't even think about buying an FM transmitter (which by the way costs more). The sound quality on the Auxillary Interface is excellent. The FM transmitter will not even come close and you don't have to worry about interference. Installation was also very easy because of the instructions provided by Crutchfield. I am a bit leery about online reviews about products, but in this case take my word for it, this is an excellent buy.


Written By Joel, Chicago, IL on Monday, June 05, 2006

I have the built-in Toyota 6CD changer, and it still works after plugging in this part. Simply hit the 'Disc' button to go to CD (the changer), then hit it again to go to CD1 (the aux input). Volume is great, and the sound is CD quality when using my iPod. I was able to drop the wire into the compartment below the gear shift in a my 2006 Matrix, so the module is out of sight but easy to reach. Installation took about 30 minutes.


Written By Tom, Belmont, CA on Tuesday, May 02, 2006

I have a 2005 Toyota 4Runner and have tried both cassette adapter and FM transmitter for my MP3 player (Creative Zen 30GB). I am blown away with how well this adapter works - truly CD quality - no trade-off whatsoever. Despite reading reviews that said it was a 10-minute install, it took me about 1.5 hours, but it was not difficult, just a little tedious (plus I took time figuring exactly where I wanted to route the wires). As a complete music fanatic who spends a ton of time driving (40,000 miles in the last year), this really is the best $70 I've ever spent. If you have any doubts about this, trust the hype!

Easy install 01Toyota Tacoma prerunner

Written By big kitchens, Prattville Alabama 01Toyota Tacoma prerunner on Thursday, April 06, 2006

I have a i pod and a roady xt.I have been using a tape adapter for my i pod for about a year now. I finally got xm radio a month ago and decided to buy this product. wow! It meets and exceeds my expectations. The ipod sounds as good as my cd player. I will warn anybody with a 01 tacoma make sure when removing the dash trim to get the radio out, that you 1st remove the air conditionar control cover. You will find two hidden screws underneath the cover.I almost broke the trim trying to get it off.
I used two belkin mini y connectors to hook up the ipod and xm. You can not beat the price at $5.00 each, and thinner than the monster cable.

2005 Tacoma with JBL 6-disc changer

Written By Tim, College Station, TX on Saturday, March 11, 2006

Crutchfield Customer Review (What's this?)

For Toyota owners with the JBL 6-disc changer, you CAN use the AM/FM radio, the CD player (all 6 discs), plus a satellite radio AND an MP3 player - all with the steering wheel mounted controls! Pretty fantastic! It's a snap to remove the ventilation controls (provided you have an interior panel tool) and the factory radio comes out with 4 bolts. An easy 30-minute job. The factory radio from my 2005 Tacoma had an additional empty plug in the back, so I was able to use the aux interface cable in that spot. I think both the Crutchfield site and the USA SPEC papework state that you CANNOT use the 6-disc changer after this install - not true (at least in my case). Great product! The volume is low with the XM radio, but that's not the aux interface's fault.

USA Spec for a 2005 Toyota Tacoma Double cab

Written By Ryan, PA on Tuesday, March 07, 2006

I have a 2005 Toyota Tacoma Double cab without JBL audio sound. It has the 6 disc in dash changer and this product works great. I mounted the unit on top of the facory deck bolted to the top case cover- in the center biased twards the rear. it took some more dash diss-assembly but I could not find a good place to mount the USA spec unit.
The XM going into the unit sounds great and I still have use of my 6-disc factory cd changer and AM/FM radio with stering wheel controls. Like all other reviews you have to turn the volume up on the XM or Ipod for it be heard.
Installation was a snap only finding a good spot to mount the usa spec adapter was a hard one to do.

Great Product

Written By Eric, Long Island, NY on Wednesday, February 01, 2006

I installed this in my 2004 Corolla for use with my XM Myfi receiver. The installation was quite easy; the hardest part was hiding the wires. I also needed a ground loop isolator, which I installed between the Myfi and the interface. It turns out, when the Myfi was hooked up to the car power adapter, I experienced a very high pitched hum. With the isolator installed, the noise is gone. The second set of inputs on the interface is used for my wife's ipod Nano. The audio quality from both sources is excellent, and this device really is a great improvement over the built-in FM modulator of the Myfi.

Device was defective

Written By Ken, Mesa, AZ on Tuesday, January 17, 2006

Crutchfield Customer Review (What's this?)

I'm traveling and was hoping to be able to install this to avoid the constant hunt for a clear station for my XM radio's FM modulator.

I installed it in my 2004 Toyota Sienna. The stereo could see both input tracks and "stop and start" them but there was no sound from either input. And, Crutchfield was then out of stock so I'll have to travel back home without one and then see if I can get one that works.

I should mention that the connector on the Y cable that plugs into the back of the radio doesn't fit well in my factory stereo. It's almost a force fit and the latch tab on that plug broke off.

It's really simple to install although they don't provide any pictures of the Y cable that identify its connectors by the names they call them in the instructions.

The device sounds like a really good solution to my problem so I hope I can get one that works.

Quick Installation, Amazing Results

Crutchfield Customer Review (What's this?)

The auxillary interface was easy to install, taking me less than 10 minutes to professionally mount it behind the head unit in my 2000 Camry. The wires matched up perfectly with the connectors on my head unit, and after maxing out the volume level on my Roady 2 (XM Radio), and turning up the volume just slightly on my Camry's head unit, I had CD quality XM Satellite Radio coming from my speakers. The sound that this direct connection provides is just so much more clear and vibrant, and I no longer have to worry about FM interference ruining my favorite song (this is even more important when traveling between cities where unused FM frequencies change quite often).

USA Spec Adaptor Works Great!

Written By Mike, Fort Worth TX on Friday, January 06, 2006

Crutchfield Customer Review (What's this?)

Installed in my 1998 Toyota Avalon without a hitch. Unplugged the cassette deck (like I need that) and plugged the adaptor into the back of the CD/radio head unit. The cord was just long enough to run it under the shifter center console into the storage compartment where I mounted it. Took me about four hours but looks very custom with no wires hanging. I place my Archos Gmini 402 portable multimedia center in the storage compartment and plug it into the USA SPEC adaptor. I use a right angle Monster cable so as not to place stress on the jack exiting the MP3 player.

I used velco strips to attach the interface to the inside of my glove compartment so I would be able to use the inputs for other devices if needed. This product sounds amazing with my ipod and it blows any fm-transmitter or tape adapter out of the water. This is a definite MUST HAVE for anyone who travels with their ipod!! A++++++

USA Spec for '04 Corolla

Written By Josh, Redding, CA on Wednesday, October 19, 2005

I ordered this part to connect my XM Radio and iPod to my stock head unit. It works great! Sound quality is better than a tape adapter or that FM mod by far! I own a 2004 Toyota Corolla, and I was able to plug the adapter into the back of my stock head unit without removing any dash pieces or the head unit itself! I simply removed the glovebox, reached my hand way up inside the dash (it's a tight fit), and after a few tries I managed to plug it in! I bought a RCA to 1/8" connector cord (not included) to connect the unit to my XM radio, iPod, etc. The volume output was slightly lower than a CD, but only slightly. (All you have to do is adjust the volume a little.) This part is highly worth the $60 for anyone who likes to listen to their iPod, XM radio, laptop, etc. over a car stereo.

What a great product. The directions are clear and precise. I am pretty much useless when it comes to installing anything in the car. I was a little hesitant but as soon as the parts started coming out as described in the manual I became comfortable and was able to install everything. I purchased a monster Y-cable and hid the wires in the side panel (also described in the Crutchfield manual). I do not carry CDs in my car anymore and all I have is my iPod Nano and it sounds perfect. Thanks

Crutchfield Customer Review (What's this?)

I have this unit installed in a 2003 Corolla with the factory head deck. I recently signed up with XM radio service and first tried the built in fm modulator.Too much noise! I wasnt satisfied with the quality so I went with the hard wired fm modulator.Still too much noise! Still not satisified I found this little adapter to directly hook it up into the cd changer input. I have had it installed for about a week now and am very happy with the job it does. Aside from a little engine whine which may be part due to the cable I used to hook to the XM reciever, it really sounds great. Is also has another set of inputs which I hooked up to my mp3 player. I had a cd changer hooked up but I think that the mp3 player will take place of that. I dont have the problem with the low volume that some of the reviews have been mentioning. The only reason I gave it a four is because of the whine which you cant hear when the music is on. The unit is real simple to hook up and requires no power. It is small enough to stash behind the dash. I recommend it.

Works great.

I installed the DF-TOY adaptor in my 2005 Toyota Tacoma Double Cab w/ JBL Sound System. I was able to easily pull the climate controls, remove the stereo, and plug the adaptor into the back of the stereo. The steering wheel controls do still function perfectly with the adaptor - allowing me to toggle between sound sources and even between the Aux1 and Aux2 inputs using the track up and down buttons. I use one source for my XM Roady radio and the other for my iPod. You will need to turn up the volume for the XM source - but this is due to the output level of the XM Roady and NOT of the fault of the adaptor.

Works As Described

Crutchfield Customer Review (What's this?)

This item works exactly as described and installation is easy--once you get the dash apart. If you have to turn the volume nearly all the way up on your music player (which can cause distortion) the remedy is simple: Get a portable headphone amplifier. Put it between your player and the input to the DF-TOY. This system works great! The sound coming out of my Toyota factory stereo is fantastic. I actually look forward to my daily commute (30 minutes each way!)

USA SPEC Auxiliary Interface

Crutchfield Customer Review (What's this?)

This adapter is wonderful! I used it today in installing a OmniFi DMP1 in my 2001 Avalon and the sound is just perfect. The volume is matched exactly with the radio and CD player, and sound is very clean. No distortion from over driving, no noise, nothing. Switching the inputs using the track up and down controls is also a breeze. From the standpoint of some one that made an auxiliary input from scratch to work with a '97 Avalon, this thing is worth every penny.

One thing that I'd like to mention for people looking at getting one of these: You CAN still use your CD player if you do not have a factory changer. Nowhere really gives any info on if you can or not, but I'm happy to say that you can.

2005 Corolla

Written By Eric, WI on Thursday, July 21, 2005

Installed in a 2005 Toyota Corolla 2005 with the factory 6 CD/radio. All the plastic dash pieces are a bit tough to get apart but the Crutchfield instructions are excellent. To access the interface from the the radio just press the CD button on the radio and it will change from CD to CD1 and accesses the interface. There is space for all the wiring. I installed the interface box with a screw into the little plastic bracket where the carpet is clipped up. I enlarged the exisitng hole in the dash compartment closest to the heater control and passed a Y adapter wire's (not supplied) mini jack end into there- makes a great spot for the iPod.

Great Product - Easy to Install on my Matrix 2005

Product is working great. It took me less than hour to install. I have it hook it up to my XM radio and Ipod and getting great sound from it.

Pretty Good, Easy To Install, Works as Advertised

Written By Mike, Somewhere in NJ on Friday, June 24, 2005

Crutchfield Customer Review (What's this?)

Installed in about 5 minutes, following the master sheet instructions ... so easy. Didn't even have to remove the head unit (lots of space to get my hand in and plug in the cable). The only downside (and what keeps this from getting 5 stars) is the volume level issue. Even with the audio output on full (from my Sirius Sportster) the volume level to the head unit is low. But as long as I have the head unit output volume high, it works great.

Simply Great

Crutchfield Customer Review (What's this?)

Some people have a little concern about the low sound levels from this unit. However the problem lies with headphone output if you use a "Y" adapter. For ipod, I bought a cable made by Nyko, one end plugs into the dock, the other end is RCA that plugs into the unit, so no sound is lost at all. Sound level is normal. Installation into my 03 Camry was so simple, the whole process took about 15 minutes! Overall, great product. Buy the Nyko iPod stereo link if you want to use your iPod in the car.

Great product - better fidelity than a cassette adapter - no hiss

Written By Jeffrey, Roseland, NJ on Wednesday, May 11, 2005

Crutchfield Customer Review (What's this?)

Nice product. Crutchfield documentation was very thorough. Installing on a 2003 Rav4 was a snap. I suggest removing the kickplate by the passenger side and snaking the wire from the radio. There is plenty of slack. The adapter sits nicely behind the kickplate and is easy to get to if you want to add another device. Connections very easy. Sounds great. I was using a cassette adapter but this is much better as the cassette adapter would sometimes move out of alignment. Plus, no more hiss from the tape head, no wire dangling from the head unit. Yes, you do need to add some volume, but there is no distortion.

Works Excellent With 2005 Scion XA/XB/TC

Written By Saul, Antioch CA on Wednesday, April 27, 2005

Crutchfield Customer Review (What's this?)

This unit works as advertised. I installed it in my 2005 Scion XA and it sounds great. If you run an input wire to Belkin's Ipod Car Adaptor, it has a built in line out amp that will correct for volume level differences. Otherwise volume needs to be a little higher than the radio but perfectly accepatable.
I would highly recommend this product to anyone looking to add inputs. It works great with my Ipod and Sirius Satellite Radio.

Easy Install onto '05 4Runner

Written By Tim, Los Angeles, CA on Thursday, April 14, 2005

Crutchfield Customer Review (What's this?)

After the initial work of finding the right bolts to take off and the correct places to tug at the various panels to get to the back of the JBL stereo on the 4Runner, installing the USA Spec Aux Interface was a cinch. It looks clean and feels as though it was built with quality in mind. My only complaint is that my notebook and MP3 player needed to be cranked up to maximum volume levels to get a decent volume out of the speakers. Not a big issue because the signal is still very clean. This is not a surprise since it is not an amplifier and there's probably considerable loss through the 1/8" to RCA wire and the USA Spec interface wire. In conclusion, this product does what it promises and does so without much fuss.

2005 Toyota Matrix

Written By pgsavage, Asheville, NC on Wednesday, April 13, 2005

Crutchfield Customer Review (What's this?)

I must say that I am extremely pleased with this product. I have used it to connect my 4G iPod to my factory Matrix stereo and it works great. I have use of my iPod as well as my CD's due to the fact that the cd changer is indash and not a seperate unit. It only took me about 25 minutes to install and the instructions were clear. My only complaint would be that the volume is not as high as when I play cd's, but I don't blast music so it is really not a problem for me. I have rigged it so the unit sits in my glove compartment and I have the mini-jact cord come out of the glove compartment and hook into the iPod. Sure I have a random wire coming out of my glove compartment but in my opinion this is not at all an eye sore. I can then stash the whole unit in the compartment.
Big reccomendation. Lacking the 5th Star only for the volume aspect.
I prefer it over the iPod specific model baecause once plugged in I still have control over the iPod and can make OnTheGo mixes and not have to be at the mercy of the "Toyota mixes" the other unit forces you to make.

2003 Tacoma Double Cab

Written By Doug, Memphis, TN on Thursday, April 07, 2005

Crutchfield Customer Review (What's this?)

This unit works perfectly with my factory unit. Sounds great with my XM Roady 2. You do have to turn the volume up a bit, but there is no background noise. Since there are 2 sets of inputs I will have to get an ipod to hook up. My only gripe is the cable takes up alot of space but I was able to hide it all behind the dash. Crutchfield gives very good instructions about how to disassemble the dash area. I would recommend this unit to anyone.

USA SPEC Auxiliary Interface

Written By Robert, Laguna Niguel, CA on Wednesday, April 06, 2005

Crutchfield Customer Review (What's this?)

My 2005 Highlander: The unit took fifteen minutes to install. Unlike most products from Crutchfield, this one did not come with a sheet to explain how to get to the back of my factory headunit. One call to Crutchfield tech support and the rep read from some notes on file on how to do it. (Pry the frame from around the center stack of instruments, remove the six 10mm hex screws, slide the unit out, and plug in the harness.) The easiest car audio installation I've ever had.

I plugged the interface cable into the harness, plugged the other end into the interface unit, plugged my iPod RCA cable into the interface, velcroed the interface under the dash, reinstalled the instrument stack, turned everthing on and it worked perfectly. Like the other reviewers, I found that the radio needed more volume when running the iPod but as my 16 year old son said, "Who cares?" I hear no background noise.

Great product. Instructions on operating the unit come with the package and are very clear. Buy it! You'll smile all the way down the road.

Yes, it works in a Scion

Written By Harrison, Worcester, MA on Friday, March 25, 2005

The first unit that I was sent had a faulty wiring harness, but as usual, Crutchfield's tech support folks were on the ball and ultimately got in touch with an engineer at USA SPEC to work out the problem. The replacement unit worked immediately. If I could recommend a feature to the guys at USA SPEC, I'd tell them to add a line amp to the thing as well--the sound from my mp3 player is much quieter than the signal from the tuner and CD player. But, I've accomplished what I set out to do--got my portable tunes going in my Scion Xa--and Crutchfield made it happen. Thanks, guys!

Great solution, while it worked (2005 Highlander)

Written By Brian, LA on Thursday, March 24, 2005

Crutchfield Customer Review (What's this?)

I initially was gonna put in my 8 month old Clarion with inputs in the back, but the aftermarket installation kit (2 Din to 1) was pretty ugly. A rep suggested this product and I assumed it would solve my problems and could ebay my Clarion.

I'm glad I didn't sell the Clarion 'cause after 3 days of using the adapter it stopped working. I unplugged it and plugged it back in and viola it worked again... for a day. Try again and got another day.

Had the thing swapped with a new one. Got 3 days out of it, then a day, then 5 minutes. Spoke with Jim at USA Spec and he said he'd look into it, but that it might take a few MONTHS.

Don't wanna live without my iPod that long, so back it goes. Now I'm stuck with a bad looking installation kit and no hope in sight.

Great idea, too bad it doesn't work.

Double Edged Sword

Written By Busyguy, West Palm Beach, FL on Saturday, February 19, 2005

Crutchfield Customer Review (What's this?)

Crutchfield's representative recommended this for my 2004 Toyota Solara as a way of enhancing the clarity of my Delphi SkyFi2 XM satellite radio. The unit allows you to avoid the wireless FM modulator thereby improving the clarity of the reception. Now it sounds clearer and more like my home digital cable stations. A definite and noticeable improvement. Commuting 40 miles to work, I no longer have to re-tune the FM Frequency station to find the best reception. It is consistently strong whereever I am. Had it mounted in the glove box and can now plug in my portable cassette player when I want to listen to tapes.

I am using the interface with my stock Toyota head unit. Unfortunately, I must now increase the volume level to hear stations. (e.g. used to listen to XM at 28-36 dcb, now it needs 51-58 to achieve the same volume) The only drawback is that at this increased volume level, I can detect a barely audible high pitch "dog-whistle" like sound since the stock radio has a heavy demand on it. Some people might not even hear it unless it is pointed out to them. I'm planning on adding an amplifier in the near future (50 RMS x 4) and will update my review.

Overall, I like the unit, would recommend it, but make sure you've got enough power to truly appreciate its benefits. Suggest you use gold-tipped "Y" mini plug for improved contact.

Product Research


Compatibility: The DF-TOY allows you to add two auxiliary inputs to the factory radio in select Toyota vehicles. The adapter plugs into the factory system using the supplied cables, avoiding wire splicing and modifications. Since the adapter is controlled by the factory radio, the available controls should be described in the factory manual.

Note: The adapter is not compatible with vehicles that have factory navigation and DVD systems. The adapter takes the place of the CD changer, so you cannot have a CD changer and the adapter connected to your vehicle at the same time.

Mounting: The adapter can be secured to any flat surface using the supplied mounting screws.

Connections: The adapter has two auxiliary inputs (Audio Input 1 and 2) on the left side panel. Each input consists of left and right RCA audio jacks. On the right side panel, the adapter has a round 8-pin jack that interfaces with the supplied CDL-TY cable. The adapter end of the cable has a round 8-pin connector that plugs into the adapter. The opposite end of the cable has a rectangular 12-pin (11 pins present) female connector that plugs into the back of the factory radio. For some newer model vehicles, you will need to plug the CAS-TA cable into the factory radio and then connect the CDL-TY cable to the CAS-TA cable.
