Add the convenience of hands-free calling to your compatible 2008-up Alpine in-dash receiver. Powered by Parrot, the KCE-400BT Bluetooth® adapter lets you answer incoming calls, place outgoing calls, and scroll through your phone book entries — all without ever touching your Bluetooth phone. In fact, once the system is set up, you can leave your phone in your pocket or purse when you get in the car — it connects automatically when you turn on your stereo.

When a call comes in, your stereo mutes the music and you'll hear the caller over your speakers. The included microphone uses Active Echo Cancellation technology to ensure that you'll be heard loud and clear on the other end.

The KCE-400BT also works with select 2008 Bluetooth-ready Alpine stereos. Check the "Details" tab for compatible models. For those receivers, you'll need the KWE-460 connecter cable.

Note: Compatibility of this device may vary, depending on your phone and service provider.

Note: Sorry, Crutchfield cannot ship Alpine products to Guam or Puerto Rico.

Product Highlights:

  • Bluetooth interface adapter for 2009-up Alpine stereos
  • send and receive calls with the stereo's controls (includes microphone)
  • supports music streaming
  • Active Echo Cancellation technology ensures noise-free conversations
  • warranty: 1 year
  • Our 60-day money-back guarantee

Alpine KCE-400BT Bluetooth® Adapter

Written By travisA, Iowa on Sunday, March 04, 2012

Crutchfield Customer Review (What's this?)

Very good product, works flawlessly with my cd-105 hu, automatically connects to phone and sound quality is excellent. Only con is that it is a little pricey.

Crutchfield Customer Review (What's this?)

I have this installed with my IVA-W505 and I have a iPhone 4S, and it works perfectly. Updating the phone book has some issues, but for the most part. It works, and I absolutely just want it to work. Not being able to use my phone while driving is a wonderful experience to have. It helps with safety as well. I have Music Match service through iTunes, and it plays my music outstandingly.

Pros: It just works!

Cons: Price, but that's always a concern with anything I buy.


Written By Steve, Springfield, VA on Wednesday, February 01, 2012

Crutchfield Customer Review (What's this?)

Equipment: I'm using the iPhone 4s, the Alpine KCE-400BT Adapter, and an Alpine IDA-X305S receiver.

Install: Easy install if you know how to remove your receiver to connect the adapter. Only 4 wires to connect...I simply spliced 3 of them into the existing wires (red to red, yellow to yellow, black to black) and then I connected the Pink/Black wire to the unused Pink/Black on the harness.

Pairing: The adapter paired to my iPhone on the first try and began playing music. I turned bluetooth On on my iPhone and it showed the adapter within 10 seconds. On the Receiver I went into the Setup Menu and set Bluetooth to 'Adapter'. Back on my iPhone I clicked on the Alpine Adapter entry and it paired immediately. When I turn off the car my music apps pause (most of them anyway). And it picks up playing from the same app/song on startup.

Performance: From my iPhone I can play audio from my Music app, any radio apps, Pandora, Last FM, and just about anything that outputs audio. The quality is nearly that of my direct iPod Cable connection. That means really good!

I have a simple dashboard mount for my iPhone so it sits prominately on my dash. I found that it plays the audio from just about any app while also displaying the picture on the iPhone's screen. This is perfect for GPS and other navigation apps. While using GPS the music fades out, the GPS speaks, and then the music fades back in. The same goes for when making/receiving phone calls.

Pros: Phone call clarity is really, really good - no echo or static whatsoever. Music quality is surprisingly great! My steering wheel controls still work (2010 Toyota Corolla S) for changing tracks and adjusting volume. I haven't had to re-pair my iPhone ever. It automatically reconnects to the adapater when I start my car (within 30 seconds) and plays music/audio from where it left off. Siri and GPS apps speaks over the bluetooth connection which make them easy to hear.

Cons: No album art, song or album information displays to the stereo receiver. It simply says 'Bluetooth Device'.

I paired it with Alpine IVA d106 and DHA S690 changer and works as it should from day 1. I have this in a soft top Hummer and people can still here me at highway speeds which is surprising.

Pros: Works with iPhone 4s

Cons: None so far

Pairing Issue Resolved

Written By JohnnyY, Glendale, CA on Wednesday, November 16, 2011

Head Unit: CDA-117 Phone: Iphone 4s Bluetooth: KCE-400bt (Firmware 311)

1. Pair a second phone to the KCE-400bt. Check to see it's listed in the paired devices on your head unit. Doesn't have to be connected. You just need more than 1 phone listed in the paired devices list. 2. Turn off the car. Put second bluetooth phone out of distance from head unit (just in case). 3. Turn car back on and WAIT about 1 minute for your phone to pair automatically. Do not interrupt it from pairing by clicking on buttons. Just leave it alone and it will pair in about 30 seconds to a minute. If your Iphone 4s (the phone I used) says it's "connected" then it's paired and you can test on the head unit.

This method has worked for me and stays connected even after the car is shut off and turned back on.

Be sure to: -Have Int Mute off -Have your phone listed on #1 of paired device list and not #5, which is the guest account. -Make sure Pink wires are connected to each other on your head unit and KCE-400bt

Pros: Scrolls through Phone book, Missed Calls, Dialed Calls, Received Calls. Works with Alpine products very nicely.

Cons: Initial setup to connect to phone properly. Voice dial doesn't work.

Installed the 400BT behind a KCE 9886 unit. Incredibly simple install, and it works like a charm, iPod also functions well and I was able to keep my aux in through the CD changer port. A great way to add longevity and functionality to an older head unit

Crutchfield Customer Review (What's this?)

works very well. any issues I have had seem to be Android related, not about this adapter. streams music and makes and receives calls very well. At first the my radio (CDE102) did not seem to want to recognize the adapter, but after a few minutes after the install it came to life and has been fine ever since. My android seems to behave much better if I turn off the music streaming, and since I don't use that, I did.

Great add on

Written By Sean, Kansas City Mo on Sunday, May 22, 2011

Love this add on for my INA-W900BT, wish it would have come with the unit. The one thing I would watch is the price. I bought it with tax for $100 less than on here. Check your Best buy they have it and it is 48.88 with tax. It however is not on their website.

I installed the 400BT to my 9886 and I love it. Even with the windows down and
the top removed, callers say they hear very little to no wind noice. Not only do I
have crystal clear phone calls but I can also stream my Pandora and other
audio thats saved on my HTC Hero. This was definitely a needed upgrade in
my 04 Vette.

Save your money and use your speaker phone

Written By Mike Z, Sacramento on Thursday, March 17, 2011

I have the 900 BT Alpine head unit. It came with the KCE 250 BT, I wanted to upgrade so I could listen to blue tooth audio streaming, I bought the KCE 400 BT, it paired, and then didn't pair, it paired, then didn't pair, etc. Also, the head unit would not recognize my Droid phone when it did work, it would receive calls, but you couldn't use the head unit to dial out as it is suppose to do, plus it would display, "no phone connection". I had all of my sound system professionally installed by an authorized Alpine dealer, and they have tried numerous times to resolve the issue and they failed each time.

I have to say, with all the bluetooth technology out there they have yet to get it right. This Alpine is the second experience I have had with using an audio bluetooth in the car, and I have to say, that bluetooth technology is extremely disappointing. My first unit sucked, and so does this one. If I could give this a minus rating I would.

Alpine is suppose to be top of the line in car audio, well they definitely dropped the ball on this one. Save your money and use the speaker phone feature on your mobile.

Alpine KCE-400BT Bluetooth® Adapter

Written By Gary, Arnold, MD on Friday, January 21, 2011

Crutchfield Customer Review (What's this?)

I am using this unit with an Alpine IVA W505 and an iPhone 3GS.

Installation is very easy, but I had a little trouble getting it up and running. There were
some initial problems getting my phone to pair which involved a call to Crutchfield tech
support and resetting my head unit. Once that was over though, I have had no problems
with it's operation. Call quality sounds great and the microphone pics up my voice
perfectly using a normal speaking volume. Nobody can tell that I'm calling from the car.

I can stream music from my phone and the sound quality is good. It does not display any
track information though and I cannot search my music from the head unit. The only
control I have from the head unit for music is play/pause, FF, and REW. I actually have to
pull my phone out to select the music I want to hear or to see what is playing.
Inconvenient, but since I was already using an iPod in my car I don't mind so much.
Function of the iPod is the same as before installation of the Bluetooth unit.

Alpine KCE-400BT Bluetooth® Adapter

Written By TJM, Denton TX on Sunday, January 09, 2011

Head Unit (Radio): Alpine CDA-9883
Phone: Droid X

NOTE: the standard wires that come with the KCE-400BT are not compatible with all Alpine radios. I had to buy two wires that were compatible (one for iPod adapter, the other for the radio unit). These cost me extra.

- Quality of phone call is very good and can listen to MP3 and other radio applications (such as Pandora) via bluetooth

- I have to unpair/pair EVERY TIME I get into the car.
- My radio unit does not allow me to do a firmware update to the KCE-400BT on my own. The instructions state that I have to take it to my dealer to have the firmware updated.
- Cannot use the voice command - you have to use the radio phone function to rotate through your phone book to dial a number.

Horrible Alpine Firmware Support

Written By Sean M, Columbia, SC on Friday, December 24, 2010

Crutchfield Customer Review (What's this?)

Alpine doesn't seem to want to keep the firmware updated for current phones. I actually ended up going back to the oldest FW I could find to get this to automatically pair with my Droid Incredible. (version 1.60 fw) I tried v2.0 and v2.51 and the phone will pair but if you shut the car off, get back in - it will not find the phone unless you cycle the BT on the phone. I have always bought Alpine head units for 20+ years of driving, but this is probably my last Alpine product. It also doesn't display any track information when playing Audio. At least it plays the audio, but it would be nice to see the .mp3 text. Update your firmware Alpine!

If it's paired it works fairly well. I have had a few odd phone reboots and one scary head unit freeze/reboot. So with my occasional light use it's ok aside from the previously mentioned issues.

Crutchfield Customer Review (What's this?)

I brought this unit and it is not what I expected. It was an easy install. I have a 2003 Toyota Highlander with an Alpine CDA-9885 head unit and LG-Vx8300 phone. It paired easily but it would not stay paired. When it worked it was great. Everytime I shut the car off to do and errand and come back I would always have to pair it again with my phone, kinda defeats the purpose because my phone is in my pocket. It is annoying when I have to take it out everytime. Crutchfield was great they send me another unit when I complained about it but the other unit was the same. I would avoid this unit.

This is fantastic

Crutchfield Customer Review (What's this?)

I have been driving a Honda S2000 for 7 years. I can't hear my handheld phone with the top up or down. Maryland law starts Oct 1 banning handheld phones. I have tried headsets and I can hear, but no one can hear me. I have an Alpine IDA-X100 head unit and installed the KCE-400BT Bluetooth® Adapter, I use an Ipone 3Gs. It is amazing! With the Microphone on the visor with top down and windows down I can be heard at up to 35 MPH. With top down and the windows up I can be heard well at 55 MPH and OK at 65 MPH. I of course can hear thru the speakers all the way up to 65 MPH. I have always been told that a speaker phone in a convertible is not recommended--well I recommend this one. I am so pleased to finally use my phone in the car. I am still working on all the features so I can't fully comment on them at this time--It just works great so far.


Written By Mike, Discovery Bay, CA on Wednesday, September 01, 2010

Crutchfield Customer Review (What's this?)

The setup was a little quirky with my IDA-X100 head unit needing a different cord. And, I had my red-wire acc looped to the yellow hot wire so I could run my tunes with the key off. This didn't set well as I had menu probs on the head unit that required a re-set which required me to undo my acc wire loop to orig config. So, after getting that all straight, the sound quality is very good. Everything seems to work as described. I am pleased with the unit.

The BEST add-on bluetooth device there is.....

Written By Patrick, Chester, VA on Saturday, August 28, 2010

Crutchfield Customer Review (What's this?)

This is a great add on to any newer Alpine bluetooth ready receiver! Very clear on both ends, very easy to install (I think it took me about 15 minutes). Supports all of my phone features(LG Ally). Connects instantly when I start the vehicle. Far superior than the factory installed devices in most vehicles. Voice dial, caller ID is great! It will interupt the source playing while displaying the caller ID on the radio and playing a ringtone through your speakers until you choose to answer the call. Very pleased with this product. A must in states that already have a hands-free law in place. Besides, it beats those stupid headsets stuck in your ear any day of the week!

I am currently using this in my 05 Jeep Grand Cherokee. I also have the Alpine CDA-117. These two items work together great. i miss read the directions, but once I got help over the phone everything worked perfectly. I am told the clarity is excellent on the other end of the phone call. Background noise in minimal and only when I go directly from the bluetooth over to the phone does anyone notice the difference. Even then it is only a slight difference with the actual phone being better. I will continue to use Alpine and I would recommend both products to anyone.

Great addition

This product has made our Alpine CDA-105 deck even better. I can receive phone calls and place them all through our Alpine deck. The best part is we now have a hands free device in our vehicle so we can pay attention to the road instead of fumbling with our cell phone and driving. I would suggest this product as a necessity for anyone who is thinking about purchasing an Alipne CDA-105. We completly enjoy it.

Better than BT earpieces

Written By Mike, Miami, FL on Sunday, February 14, 2010

Crutchfield Customer Review (What's this?)

Very easy install and good functionality. My only issue with this adapter is that it does not
receive phonebook information from my cell, which was listed as compatible with a Parrot
3100 BT device. I am using a Verizon G'zOne S cell phone and the BT adapter is connected
to an older Alpine CDA-9883. While I cannot access my phone book through the head unit, I
still see the phone number of incoming callers on the head unit display and it automatically
answers after about the second ring. BT signal strength with this Alpine adapter is much
stronger/better than any BT earpiece I have used in the past (and I've tried out a bunch).

Overall, very good BT unit, despite the phonebook shortcoming.

Was easy to install right out of the box as I found most Alpine products from Crutchfield.
I have been using it quite often since I got it and everyone says I am clear on the other
end and I have no problem hearing even with the window cracked. Easy to use with
CDA-105 Receiver and if there are any limitations it would be in the display capabilites
of the recevier. Great product would recommend to anyone. This is the 3rd or 4th
product I have bought from Crutchfield recently and I am very impressed with how
thorough the information is and what is included free with my purchases.

Tired of the Ford stereo in my truck -- a 2000 F250 Diesel - I puchased an all-Alpine
system of the CDE 102 receiver, the KCE-400BT bluetooth kit, and 4 SPS-507 speakers.
The result -- Awesome! Great, great sound and flawless operation. My Iphone plugs in
the adapter (or into the front Aux port) and the sound is as good as it gets. The speakers
rock the truck -- and I hear things in my music that I have bever heard before. The
receiver is very easy to operate and adjust. The blue tooth works perfectly, even with the
diesel engine noise. My wife says the bluetooth in the truck is better than my Lexus 600h
sedan! Nice job Alpine & Crutchfield -- I wish I had done this years ago.

Great addition to my TT

Written By Whiskey Robber, Alexandria, VA on Thursday, January 07, 2010

Crutchfield Customer Review (What's this?)

I installed this device with my older CDA-9885. Installation was pretty straight forward with the diagram provided by Alpine. I was able to tuck the box (about the size of a deck of cards) under the head-unit in the dash. The trickiest part was soldering the leads to the head unit's harness. As always the Crutchfield folks were helpful when I called with a few questions.

Please note a few issues that I encountered:

1. If you are adding this unit to an older head unit (like my CDA-9885) and you want to continue using your iPod, you'll need the more current iPod cable: Alpine KCE-433iV iPod® Cable.

2. If you have an iPhone, you cannot take advantage of the "voice activated" dialing as the iPhone uses it's own voice dialing system that's not compliant with the "voice activated dialing over Bluetooth" that the Alpine KCE-400BT uses. Hopefully Apple will address this with a future software update.

This was for the Alpine Bluetooth box. In respect to my #2 point, there seems to be info from Apline that suggests the older CDA-9885 is the reason that I cannot take advantage of the voice over Bluetooth functions. One Apline tech told me that it was the iPhone, and a second said the the phone is fine, it's the fact that I have an older Headunit.

I just purchased and installed a KCE-400BT with an older Alpine CDA9883 and a not so feature rich Samsung SGH A237 cell phone.
Once you get the radio configured to support the Bluetooth adapter and synch. up your cell phone (takes just a second and I have over 250 contacts). The unit is now opperational. My XM radio seems to sound better now as well my IPOD,.. The Bluetooth phone feature is so awesome its amazing. It's crystal clear and easy to use vs stumbling for the phone in my pocket while driving,..
Its GREAT!!!!!!

Crutchfield Customer Review (What's this?)

This Alpine Bluetooth interface is fantastic. Hook up was fairly easy, had to remove my Alpine CDA-105 so I could plug in the cables. Then all I had to do is go into the settings menu on my LG Dare phone, and tell the phone to connect to the bluetooth device. Pretty simple. Not much else to it. Everyday when I get into my truck and start the engine, my cell phone automatically connects to my stereo, and if someone calls I never have to pick up the phone, I just push a button on the radio, the music is automatically muted, and I can talk to the caller over the stereo speakers. All the numbers stored in my phone, including dialed and recieved calls are shown on the face of the stereo. I never have to pick up the phone while I am driving to make or recieve calls. It's easy, and safe, and in my opinion this should be standard equipment on every vehicle made. There would be so many less accidents and deaths on the roads due to inattention and distractions.

Kudos Alpine!

pretty cool...very clear

Written By jon, Hawaii on Thursday, May 28, 2009

I hooked this up to the IVA-W505 and it works great; meaning the sound quality and calling feature. What I don't like is that the call log doesn't work as it should and doesn't call up my recent calls or favorites (I have an iPhone 3g). I also had to go this route even though I bought the navigation which comes with blue tooth (evidently the navigation doesn't pair well with the iPhone 3g). I'm actually disappointed with Alpine, they should meet with Apple to make the iPod/iPhone functions better and more user friendly. My last complaint is with my address book on the screen, it shows it in Alphabetical order, so you have to scroll and you can't search. I'm happy with the fact that I have blue tooth in my car, perhaps it wasn't worth the price, but my jawbone wasn't cutting it. Hope this helps.

Bought this as both Alpine and Crutchfield indicated it worked with the Apline CDA9886 Head Unit. But apparently it only works with late 2008 models that have updated firmware. Unfortunatly mine was not one of those so couldn't get the BT or the IPOD to work. So going back to portable BT, and older Ipod cable which worked flawlessly prior to this detour. Botton line, if you have a 9886 you should do the extra research to make sure it has the latest firmware, and don't forget you'll need a different interface cable KCE 460 and the newer IPOD cable KCE-433iv.

I bought this yesterday and received it this morning. (Great shipping
speed!) It took me just over an hour to install once i had all the required
tools. The power wire harness that comes with it has The yellow, red,
ground, and purple (w/black stripe) You need to be able to either solder
these into the H.U.'s harness or simply splice into it. Other than that the
product is extremely easy to install. The only steps left are hooking up the
mic wire, the interconnection cable and finding a mounting spot. Pairing
with my LG Dare (Verizon) was extremely easy and I had no problems
syncing the phonebook with the unit. Also plays Bluetooth audio very well. I
am using the IDA-x100 Digital Media Receiver with this adapter. In order to
use some models from 2008 you need the KWE-460E wire adapter kit.
Check my review on that product for compatible H.U.'s from 08' On my
receiver the iPod does not even use the full speed cable. It simply has a
USB cable that bypasses this product completely so no issues there. Call
quality was great and there are no echo's. Voice dialing worked flawlessly.
Great product!
