Simplifies install

Written By A. K., California on Friday, September 11, 2015

Crutchfield Customer Review (What's this?)

Paired with an PAC SWI-RC, this adapter really simplified my installation of a Pioneer AVIC-7100NEX into my 2007 ES350. They allowed my to do most of my soldered connections on the bench and then just plug and play once I had the old radio out. Volume levels are good with the TATO set at high gain. No more than the typical distortion levels noticed.

Pros: Beats cutting the factory harness. Really speeds up the installation while utilizing the factory amps. Integration with the SWI-RC couldn't be any simpler if you are keeping your factory steering wheel controls.

Cons: Would have been nice if both plugs to the TATO where on the same side to make the installation a little cleaner but it's a minor issue.

Simple and painless install!

Crutchfield Customer Review (What's this?)

This was great and I only had to connect a couple wires (3 if I remember correctly) because this already had it all done. It was kind of big so hard to get it to fight right behind the unit because it was a tight space but I got it to work.

Pros: Wiring already done

Cons: Size

Short life span

Crutchfield Customer Review (What's this?)

I am really not impressed with the PAC tato. I am now on my third unit since I installed my App Radio 3. The sound quality is fine, although a little quiet.

Crutchfield has so far replaced the bad PAC units w/o question. Looking at some of the reviews here and on other websites, I'm surprised Crutchfield still carries this product. When this unit dies on me (I prob have about 3 months) I will be shopping a different brand, which seems to have a more reliable unit.

Pros: connections are simple

Cons: junk, bulky, and built to fail.

Cheap, but functional so far

Written By Andy, Michigan on Thursday, June 04, 2015

Crutchfield Customer Review (What's this?)

I bought my nephew a new head unit for his Prius and we spent a weekend afternoon installing it. There were a few snags, but this cheap device was the biggest headache.

The first issue is my fault for not reading ALL of the directions before starting. I removed the old head unit before following the instructions to set balance/fade to center and volume high. Make sure you do this before removing your head unit. It wasn't a big deal to plug it back in, but it was a minor setback.

The second issue is that when we connected it, we only had sound out of the left side. I noticed that if I moved the wires slightly, the right side would turn on. I searched all over trying to find a loose connection. I finally decided to open the little black box that the RCAs come out of. I couldn't find anything in there that was loose, but moving the other big black wire around seemed to trigger the connection issues. After about an hour of working on this, I decided to just wrap it tightly inside the black box and clamp it down. I shook it around and couldn't get the right channel to drop out again. I don't feel great about this solution and don't know how long it will last. This unit shouldn't have made it out of the factory.

I'm sure Crutchfield would have replaced the unit but I was only visiting for the weekend and we had to make it work. Hopefully I won't be coming back in a few months looking for a replacement.

Pros: Works and sounds great

Cons: Fragile and I have no idea how long it will continue to work

failed after a couple of years

Written By meep, no. AL on Tuesday, May 26, 2015

Crutchfield Customer Review (What's this?)

at best, it worked if the balance and fader were left centered. It's a bulky and clunky setup with two boxes wired circularly and then to the radio and the vehicle harness. The sound was clean and it seemed to work fine. After 1.5 yrs the left front speaker started to distort and I thought it was the speaker, so I replaced it. It got worse however and the speaker started cutting out entirely. Then the right front started doing the same. I have re-checked all connections and it seems to be something in the DIN connector on the PAC. cleaned it, even added electrical grease. worked great for another day. I resoldered all of the pins from the 2 main connectors on the PAC. still no improvement. Junk. I like Crutchfield, but I'm buying an amp from somewhere else at a better price as this thing was garbage. I will think twice in the future when replacing these complex factory systems.

Pros: worked well for over a year

Cons: awkward harness to install. fails after a year. doesn't properly balance or fade. seems to be multiple reviews with the same mode of failure. not a brand I will ever use again based on my experience.

Crappy and they know it

Written By Rauenzahn, M, Nevada on Friday, January 02, 2015

I got this adapter at 50% off when I bought my head unit...where did I buy it? Crutchfield. There's a theme here so let me get to it. During the first six months of the install, it worked well, OK. Distortion not great and the potentiometer to adjust gain had no impact when adjusted. Then about 11 months in, the amp started to cut out whenever I hit a bump. Not alot, just some of the time. I waited for a couple of days off work and ripped into it. I found what so many others know-the pin plug jack is plastic, flimsy...well its junk. Anyway, I thought maybe it was me and bent the male housing a bit to tighten the fit. Two weeks later, it's back. Took it apart, taped it tight hoping it would hold up...first good bump, stereo is cutting out at amp. OK, I email Crutchfield. Now before I go on, you all know there prices are not the best-their service well that's where the extra few bucks pays. Except this time. I called and because it was out of warranty by a bit, they offered, get this, a replacement at 50% off..wait, that's the discount found with EVERY stereo! Well before I spend another $ with them, I bought a metro....MUCH better, MUCH easier install, MUCH better quality and sound control. Lesson learned? Don't spend my money at Crutchfield. After YEARS (like 20) of buying I'm done with you all...this item is JUNK.

Pros: Nice packaging...well sealed in package. Required scissors to remove...

Cons: It's junk. Crutchfield knows it. Amazon knows it. I know it....NOW you know it...

Cons: Bulky, hard to get it to fit neatly in dash

Great interface, follow the instructions

Written By Dr. Choc, Greenwood, SC on Friday, September 26, 2014

Crutchfield Customer Review (What's this?)

Just used this interface to install a Kenwood head unit in our 2004 Toyota Sienna. I did experience some volume loss as others have noted, but the volume adjustment described on page 2 of the instructions solved it for me. A few things I wished I had understood better as an installation newbie: (1) Even though you are purchasing this wiring interface, you still have to make a few (approximately four) wire connections between this interface and the aftermarket stereo, because the interface is specific to the vehicle but not the radio--I just used a wire stripper, crimp caps, and electrical tape; (2) Match the wires color for color; the instructions may use different terminology for the wire function than the radio's manual uses, but the yellow wire goes to the yellow battery wire on the radio, and the red wire goes to the red ignition wire on the radio--not just "accessory"; (3) The 11-pin harness and the bullet connectors are used only if you have additional wiring components. I'm sure all these things are elementary for anyone who has done this before, but they weren't obvious to me when I opened the box and saw all those wires. Overall the installation was easy. Just follow the instructions carefully and don't overanalyze them.

Pros: Works great, does exactly what it says it does.

Cons: A little bulky but actually did not require as much space behind the the head unit as I expected. The instructions could be a little more clear on a couple of points.

Needs more structural support

Written By DJ Jason, Chicago, IL on Sunday, September 14, 2014

Crutchfield Customer Review (What's this?)

I had to buy another TATO after my first one failed after only 15 months. The cable coming out of the DIN plug lost connection to the front left speakers, even though it was carefully secured behind the dash board. I had to buy a whole new TATO (at full price) to replace a cable that failed on my original TATO (which was purchased at a discount with the original radio purchase).

Cons: Bulky Necessary to get audio from HU to amp Added wiring

Crutchfield Customer Review (What's this?)

Overall I understand the unit needed this interface, but Holy Cow, what a space hog behind the unit in the available space. Took a lot of manuevering to figure it so the unit fit back into the limited space.

Pros: Functionality

Cons: Size! And length of wires. With longer wires I could have placed this added unit in another behind the dash location, run the wires between locations just fine and been done with the install in 1/2 the time. As it is, this is a big Space Hog! But necessary ...

Had to get this because my 2004 Toyota Sienna came with the factory JBL system. (I couldn't just hook up to the speakers. ) This adapter was a snap to use & made this simpler than any other car audio install I've done. About 20 minutes total.

worked perfectly

Written By heyzarling, Hustisford, WI on Monday, August 11, 2014

Crutchfield Customer Review (What's this?)

This gadget has worked perfectly for me thus far. Maybe a little larger/more cumbersome than I'd like, but I had plenty of room so didn't matter. For what it's worth, I needed the output using a Sony head unit and the car's built in JBL amp (Prius), so the dip switches were appreciated; I went straight to +7 and it sounds entirely adequate.

Pros: Easy, inexpensive, works as described.

Cons: None

No big problems with installation or execution

Written By JonS, Denver, CO on Monday, June 30, 2014

Crutchfield Customer Review (What's this?)

Installed in a 2004 Toyota 4Runner along with a Pioneer head unit. After a call to a very helpful tech support guy at Crutchfield, installation went perfectly smoothly. I am no stranger to working with my hands or with electronics, but I have to admit some intimidation heading into the project. This adapter really helped, though the instructions could have been better. The only problem I had - and it was minor - was stuffing all the components into the dashboard in a way that allowed the new head unit to fit correctly. The various parts of this adapter are relatively large (I'm surprised they couldn't be made smaller), and there's only limited room back there. In the end, everything fit, though, and it's working just fine. Make absolutely sure to turn the factory head unit's volume way up and to center the balance and fader controls before pulling the factory unit. That's supposed to avoid the fading in and out and low-volume problems some have reported.

Pros: Easy installation.

Cons: Printed instructions that came with the adapter could have been better. It's pretty large and was difficult to fit in behind the head unit.

worked but faded in and out between rear and front speakers when using fading. Also dip switches to increase volume hardly did anything.

Written By Eric, Kansas City on Wednesday, March 19, 2014

Crutchfield Customer Review (What's this?)

This factory adapter works perfectly. All the connections are solid, everything works as expected. My only complaint is that there were actually two complete harness assemblies included. One that specifically fit my Toyota Sienna's factory plug (which only used 3 out of the 16 pins/connectors in the plug) and another which didn't terminate in a plug at all, just 16 color-coded wires. As it turned out, while I was opening all my packages - stereo, wiring harness adapters, dash kit, steering wheel adapter - the Sienna specific harness got hidden under some other packaging. My own fault. However, the instructions did not reference the Sienna specific adapter. They referenced the other generic adapter with all the wires and simply said to insert connections into slots 6, 7, and 8 in the Sienna plug. It was clearly illustrated which slots to connect to and which color-coded wires went where, so that's what I did. It took a while to figure out how to insert stripped wires into a pin/plug, but I struggled through and with a little electrical tape, got it done. Connections all worked fine, just like they should. Then, after I get everything installed, dash put back together and I'm cleaning up, I come across the Sienna specific adapter. Well THAT would have been a lot easier! So again, mostly my own fault, but the confusion of including unnecessary parts and referencing them in the instructions loses one star from me.

Made simple

Written By spk, el paso, tx on Friday, March 14, 2014

Crutchfield Customer Review (What's this?)

When I pulled this out of the box, I scratched my head. But after looking at the directions and when I removed my old radio, it made sense. Would recommend to have it mostly hooked up before you try to when installing.

Pros: Made simple to retain everything. Steering wheel controls work great.

Cons: There is a delay when you change a setting, but not that bad. Should include a little more for steering wheel instructions. Maybe a universal type.

Written By Fireray5, Douglasville, GA on Wednesday, January 15, 2014

Crutchfield Customer Review (What's this?)

Well, this product does pretty much what it says, as long as you follow the installation instructions exactly. There are some minor glitches with the sound fading in and out a bit. It's not significant, but you can hear it occasionally. It is worth it if you want to keep using the OEM amplifier with an after-market head unit. Combined with Crutchfield's outstanding tech support, a really good product! Thanks, Crutchfield!!

Pros: Keeps factory amplifier functions (volume, balance, fader, etc.)

Cons: Occasional minor volume fluctuations, bulky


Written By Martin, Yorba Linda, CA on Tuesday, January 07, 2014

Was easy enough to install, however I was not really satisfied with the power output. The instructions were relatively clear, easily installed in about 45 minutes (including replacing the factory deck). Sound is still good, but would like a little more volume (I did play with the dip switches, but not quite enough volume for my liking).

Pros: easy to install

Cons: not really a lot of volume

For 2006 Tacoma Sport

Written By Peter, Orange on Monday, January 06, 2014

I purchased this product along with the new Pioneer stereo I purchased for my 2006 Tacoma Sport with JBL audio. First of all when I purchased the product, they forgot to give me half of the harness so I was trying to attach wires that didn't exist! Then when they gave me the right product I was easily able to install the harness, however my speakers now sound terrible. I am completely dissatisfied with this product and don't recommend it to anyone.

Pros: Easy Install, kinda.

Cons: Horrible audio sound.

Excellent adapter for factory JBL system.

Written By JCjr, Indianapolis, IN on Thursday, January 02, 2014

Crutchfield Customer Review (What's this?)

Worked perfectly with my new Pioneer HU and the factory JBL system in my Toyota Sienna! No issues making all the wiring connections. However, it would've been much nicer and easier for non-professional installers like myself if there was a specific harness for the HU that didn't need splicing and connecting wires - just snapping harnesses together! I wouldn't mind paying a little extra for that option (if there was one ;)) since I don't do installs everyday.

Pros: Works perfectly with JBL system and makes for better sounding music in the vehicle.

Cons: As I said in my review (which is not so much a Con), it would've been nicer if there was a specific wiring harness that would just snap in place for the HU.

I gave this 4 stars, it does as advertised but I think it is expensive for what it is. It allows me to use existing amp and speakers

Pros: Works great

Cons: Some splicing was required, that wasn't clear to me at purchase and I thought it was all plug ins. It did make me call Crutchfield support and they were fantastic. So a con for the product equals a pro for Crutchfield :)

Crutchfield Customer Review (What's this?)

I bought this to install a Pioneer AVH4200 in my truck with the JBL system. I read through the instructions even though I felt I didn't need to. Luckily I did because you need to set your level before unplugging the old radio and learn how to easily set the dip switches. A very easy install and worth every dime just to be able to utilize the rest of the system.

The main problem I had and it was no fault of the adaptor was being able to stuff all of the connectors and the adaptor into the dash behind the radio. Toyota doesn't give you much room.

Pros: Easy to install and set up.

Cons: none

Written By Chris, Houston, TX on Saturday, July 13, 2013

Crutchfield Customer Review (What's this?)

Worked terribly for a few weeks, then just got worse. I installed this to integrate with a 10-speaker JBL system in a Toyota, and the results were awful. The sound quality was quite poor. It sounded like the music was being played inside a can, or with old speakers. Adjusting the pins on the unit and the equalizer on the HU helped a bit, but not much. The factory HU sounded worlds better.

Also, there is a delay when the HU tried to fade speakers and when the factory amp responds. So the navigation, which is supposed to reduce the volume of the music for route instructions, sounds really weird, and sometimes the music gets loud along with the nav voice. Sometimes it wouldn't mute the music at all so you couldn't hear it. Depended on the length of time it was talking.

Then, after about a month, it started going wonky and random times. It would start cutting speakers out randomly, so the music would fade to the back, then to the front, then to the right, obnoxiously. And it started putting static in the front left speakers.

I've had nothing but trouble with it. I'll be pulling it out and just replacing the factory amp and manually connecting some of the speakers to it. It's a shame there isn't a real solution for what is a fantastic factory system. Waste of $.

Pros: Easy to install

Cons: Sounds like garbage

OK, does what it is supopsed to but mixing does not seem smooth

Written By JC, Seattle Area, WA on Friday, June 28, 2013

Crutchfield Customer Review (What's this?)

Works just fine and does what it's supposed to r/e integrating w/my OEM JBL system. One issue and I'm not sure whether culprit is TATO or Kenwood 990HD deck I installed it with, but when adjusting the mix/position of sound field, the audio transition is choppy and uneven vs. gradual and smooth. This does not prevent you from achieving a great mix however. Also the volume is not optimal (seems output is lower than it should be even with the designated dipswitches engaged).

Pros: Works and sounds good

Cons: Mising seems "choppy" and volume output seems low

PAC TATO Design Problems

Written By SteveB, San Antonio, TX on Monday, March 18, 2013

Crutchfield Customer Review (What's this?)

Purchased the PAC TATO to assist in the installation of a new sound system in a 2004 Toyota 4-Runner with a JBL sound system and ten speakers. TATO caused the speakers to cut out and stay off. After much investigation, it was discovered that two of the TATO outputs were too hot (4.75 volts) for the JBL amplifier, which caused it to shut down. Replaced the TATO but the replacement unit did the exact same thing. The problem could be associated to those vehicles with nine or ten speakers.

Cons: Two outputs on the TATO overloaded the amplifier and consequently caused the amplifier to shutdown without any sound from the speakers.

When i bought my Sienna XLE brand new in 2004, I did not get a Navigation because it only came with leather seats. I'm not a leather seat fan so I planned to install an aftermarket. I looked for a navigation to install that will work with JBL during that time but none were available. Recently, an adapter came along, which was PAC Toyota and worked with my JBL system flawlessly.

Pros: Ease of use

Cons: Long wires. A lot of wires are not necessary if an adapter for the adapter is bought.

Crutchfield Customer Review (What's this?)

I have a JBL system in my 2006 Tundra and wanted to replace is with a Pioneer AVH-P3400BH. Crutchfield recommended this unit to allow the existing JBL amplifier to be used. This was a great plug and play solution. Everything works great and my system sounds great. Thanks Crutchfield!

Pros: Easy plug and play

Cons: Kind of a big control unit box. It fit though.

Crutchfield Customer Review (What's this?)

This is a great product, easy to install. My Kenwood BT645U sounds great with the JBL system in the Corolla now. My only complaint is that the volume can't quite crank up as high due to the 2V head, but the manual does state that it recommends 4V. Overall, I'd recommend it to anyone looking into installing an aftermarket deck in their Corolla with JBL system. I don't have steering wheel controls, so I cannot comment on that aspect of it.

Pros: *Easy to install *Sounds great *Fade/Balance settings still work for all speakers

Cons: *Price *Needs a 4v deck to really take full advantage

Crutchfield Customer Review (What's this?)

I found the directions very vague and the module to be kindof bulky. I had a hard time trying to fit the module behind the radio.

Pros: Made me able to install my aftermarket radio in my 08 toyota tacoma.

Cons: Very confusing directions, and theres not alot of room for the modules to go.

Installed in an '05 Sequoia with nightmare JBL Nav system. Works well, but depending on the head unit you are replacing you may need to wire it differently. On the Pioneer DVD-2300 only plug in the front right and left RCAs and all four channels will play but you will not have fader control. If you plug in all four RCAs, the audio will fade in and out. Had to surf the web to find that out and almost returned it before giving it a try.

Very easy streight plug in to factory plugs without any modification to the original wiring harness. Easy install instructions. Great discoount by Crutchfield when I purchased along with my JVC CD/Tuner head unit.

Pros: Super easy install

Cons: My volume is low, not sure if it is the JVC unit or due to intergration using the TATO

Great little gizmo. Saved a whole bunch of re-wiring. Works perfect with my new stereo/JBL amp. Instructions prefectly clear. All in all a great deal. Thanks to Crutchfield for the professional service and after sale service. The unit was missing from a badly mangled box on the original shipment. Replacement was received the next day.Thanks to the Cruthcfield crew.

Pros: Greatly simplifies new installation.

Cons: None

Easy to install and works great with my new clarion stereo. My only issue was not being able to use the steering wheel audio controls. The plug did not fit....Maybe there is an adapter, but I didn't look into it, as my radio came with a remote control anyway.

Does this work?

I had a problem in my 04 4Runner with low volume. I ended up having to add line drivers to
the front and rear channels to make the volume equal to what the factory stereo had. Other
than that, the sound is great!

Tight fit, but works

Written By HappyCamper, Montgomery, AL on Tuesday, February 22, 2011

Crutchfield Customer Review (What's this?)

I used the TATO harness to install a new head unit into my 05 4Runner Ltd. with
6 Disk RDS system. The TATO unit was easy to connect. I followed the
Crutchfield instructions to the letter and had no problems at all. (I maxed out
my volume on the old unit before shutting down and beginning install; no low
volume problems for me)

It all went together, but I agree with some reviewers that it is a tad big and
cumbersome to install behind the head unit. Not a ton of space back there. That
is why I gave it 4 stars instead of 5. Once installed, HU works perfectly and
install kit fits like OEM (Scoshe). After two weeks, TATO unit still works
perfectly. I've tried, but I can't hear any buzz or noise from the TATO or any
other components. Seems well built.

Long story short, this head unit was installed just two weeks prior in my old
vehicle, which is no longer with us. One call to Crutchfield, and I had a super
deal on what I needed to move it to the Toyota. Most retailers would have said
sorry, but not Crutchfield. That is why I keep coming back. I wish I had a
retailer like this for each of my hobbies.

Good Product

Crutchfield Customer Review (What's this?)

This went into a 2006 SE 4Runner non-nav JBL/six disk. I was very skeptical
about how the PAC TATO would work and sound after Googling but it was cheaper
than a head unit AND amp install. Man, am I glad I tried it. The unit was
simple to wire (only four connections for me) but a major pain to fit due to the
non-existent room in the head unit cavity of the 4Runner and the size of the
TATO. But, remarkably, it sounds better and plays a tad louder than the stock
JBL system. This is more from the Kenwood HU I installed but the TATO
didn't introduce any noise or other audio anomalies and works as advertised.
Just remember to set the DIP switches as per the manual for your vehicle before
you install it. OIther items from Crutchfield for this install:

Kenwood DNX-6960
Kenwood Sirius Cable
Sirius SCC1 Radio Receiver
Kenwood iPod adapter cable
PAC SWI-JACK (steering wheel control interface that plugs into the TATO)

I didn't give the TATO a 5 star rating because PAC should make the durn housing

Simple Wiring Connection

Crutchfield Customer Review (What's this?)

I purchased the PAC Toyota Factory integration adapter to connect my new Kenwood 545 receiver to the factory amps. Wiring was easy, although I studied the diagrams for a while and connected everything up on my kitchen table before moving the receiver with adapter to the car.

One recommendation -- check the maximum volume with the radio connected to the car but not mounted; I had to adjust the gain on the integration adapter after installing the radio, but it was an easy 2 minute job to pull the stereo back out and adjust the dip switches.

Overall, easy installation with good sound.

Crutchfield Customer Review (What's this?)

I put the PAC TATO in a 2005 Toyota Sienna. I had no problems with the wiring. In fact this product worked easily with the SWI-Jack from PAC as well. This allows the steering wheel controls to still work with the aftermarket radio. I have had no problems with either of these PAC products and ample room to place them behind my receiver. I only wish the PAC TATO and SWI Jack were a little cheaper. I did save money installing it myself though.

Crutchfield Customer Review (What's this?)

Product worked (somewhat) for about a week. Produced poor quality sound, and gain adjustments didn't do anything. Failed hard at that point. Put OEM radio back in and system sounds as good as it ever did. Will be switching to a stand-alone amplifier and running wires parallel to the existing wiring harness (bypassing OEM amplifiers). That way I can upgrade the system and still be able to quickly revert to the factory system when I sell the vehicle...

Check your Pre-amp voltage

Written By maragocho, Phoenix, AZ on Sunday, January 10, 2010

Crutchfield Customer Review (What's this?)

Make sure your head unit pre-amp output voltage is AT LEAST 4V. I bought a unit with a 2V preamp voltage and the gain was GREATLY affected. I had to order a different head unit. Luckily Crutchfields customer service is supurb and they swapped the unit out no problem.

A lot of plastic to jam into your dash. Had to use plastic tape to keep the large black cord plugged into the unit. Made inserting the receiver a real challenge.

Makes hooking up the stereo easy.

Didn't help the i100 work in the 4Runner. I suppose it is working for the CDA-9886.

Works Great!

Crutchfield Customer Review (What's this?)

Purchased this for my 2005 Tundra Doublecab with the JBL upgrade. It took literally 3 minutes to hook it up to the factory harness and aftermarket head unit. My stock speakers sound better with the new head unit and I keep the factory amp performance. The downside is to keep my steering wheel controls, I have to purchase another unit on top of this one for the same price. Lame.

Product Research


Overview: The PAC TATO JBL amplifier turn-on interface for Lexus and Toyota CANBUS vehicles is designed to retain the use of the factory JBL amplified audio system when the factory radio is replaced with an aftermarket radio. When installing an aftermarket radio with a 4-channel RCA output, the TATO will retain the factory functions of balancing and fading through the factory JBL amplifier. The TATO is also compatible with Synthesis 5.1 and 7.1 surround systems.

Note: Be sure both the front and rear RCA outputs from the new radio are full range.

Vehicle Compatibility: The TATO is designed to work with select Lexus and Toyota CANBUS vehicles that feature a JBL audio system; please confirm fit with theCrutchfield vehicle selector.

Gain Control: For the best sound quality adjustable gains are provided on the TATO for optimal listening. When initially connecting the TATO to the vehicle's JBL audio system, the max output might not meet that of the factory radio. If the volume is low you can adjust the output using the integrated dip switches on the side of the module. It is recommend to use a 4 volt RMS capable aftermarket radio.

Installation: The interface is installed behind the radio, with plug-and-play audio signal connectivity to the factory JBL audio system. A hardwired constant power, accessory power, ground and dimmer lead connection are also provided.

Steering Wheel Remote Compatible: The PAC TATO can be used in conjunction with the PAC SWI-RC steering wheel control interface (541SWIRC, sold separately).
