  • Factory radio must have a 14-pin CD changer port.
  • If your vehicle is equipped with an external factory CD-changer, it must be disconnected.
  • Not compatible in vehicles with factory DVD Navigation or factory rearview camera.
  • Not compatible on Acura vehicles equipped with AcuraLink.

Bluetooth Music Streaming: Thanks to built-in Bluetooth 2.0 with support for A2DP, you are able to wirelessly stream stored music and music apps (using SBC codec only) from your Bluetooth-enabled smartphone or portable audio player to the Crux BTS-HN2 and your vehicle's factory radio. There is no music control or song/artist information on the factory radio; this will still need to be done from your Bluetooth source device. You can also use Bluetooth to hear navigation voice prompts (factory radio and adapter must be in Bluetooth mode). The adapter will only pair to one device at a time.

Notes: The Crux BeeLine series adapter does not support Bluetooth hands-free phone communication.

USB Port: The adapter's USB-A 2.0 port supports playback of MP3 music files stored on a USB mass storage class (MSC) device, like a USB thumbdrive (you may want to purchase a USB extension cable). You can control Track Up & Down from the factory radio or steering wheel controls (if equipped). The factory radio will not display song/artist information. The USB port can also be used to charge (5V/0.5A) your smartphone.

Aux Input: There is a 3.5mm auxiliary input for connecting almost any external portable audio source with a headphone jack or analog audio output. Music from your connected portable audio source will be heard through the factory radio and speakers. There are no playback controls or song/artist information on the factory radio.

Magnetic Vent Mount: The Crux BTS-HN2 comes with a magnetic vent mount for your smartphone. The mount works with most air vent configurations found in today's vehicle's - including horizontal, vertical, and round air vents. The vent mount includes a magnetic device cradles and comes with a self-adhesive magnetic plate which attaches to the outside of your smartphone or inside of your smarpthone case. Once the magnetic plate is installed, simply hover your mobile device over the cradle and it will quickly snap into place and remain there. You can quickly remove it too. The mount's ball-and-socket mechanism allows you tilt your smartphone up or down, turn it left or right, and rotate it 360-degrees. You'll be able to mount your device in a vertical (portrait) or horizontal (landscape) orientation.

Plug-&-Play Harness: The Crux BeeLine series BTS-HN2 features an attached 30" harness which plugs into the 14-pin CD changer port on the back of the factory radio. The factory radio will need to be removed from the dash in order to gain access to the 14-pin CD changer port. If there is a factory external CD changer already plugged into this port, you will need to unplug it and leave the CD changer disconnected.

Operation: The Crux BTS-HN2 is accessed through the "CD" button on your vehicle's factory radio. In this mode the factory radio will display "CD1 01". You cannot manually switch between the inputs of the BTS-HN2. Instead, the BTS-HN2 automatically switches for you based on what device you have connected - Bluetooth, USB, or Aux (only connect one device at a time).

Customer Q&A

will cassette player on 2006 honda crv continue to work?
[ David  Apr 17, 2021 ]
1 answer
My car is a 2007 Honda Accord. It has a cd changer rather than the cassette player. Installing it, did not affect the operation of my cd changer. It simply took the place of XM radio in the port on my stereo. Crutchfield also sells a splitter that will allow you to keep XM and Bluetooth.
[ BRIAN D  Apr 27, 2021 ]
How do you allow phone calls to bone through the Bluetooth adapter? 2005 Honda Accord with iPhone?
[ Jenny  Feb 13, 2021 ]
1 answer
This type of Bluetooth interface doesn't support phone calls through the car speakers, as it wasn't intended to (it would need to have an external microphone connected to the interface, and be able to send that audio back to the phone, which it can't do). This interface is intended purely to stream music to your car speakers over Bluetooth. If you wanted to have "speaker phone" functionality over Bluetooth, you would likely need to upgrade the entire head unit/receiver to a model that has Bluetooth and comes with an external microphone (which you would need to run the wire behind the dash and up into the headliner near the windshield). On this device, if you get a phone call while playing music, the music will simply pause and you would take the call on the phone as if you were outside the car. Hope this helps!
[ Stephen  Feb 14, 2021 ]
I have a 2006 Acura MDX touring with Bose but without navigation what will I lose by using this and will it allow me to use the steering wheel control for hands free?
[ Angela Perry  Feb 06, 2021 ]
2 answers
We put this in our Odyssey and it took over one of the inputs on the back of the stock radio. CD-4 that I think would have been used for XM radio if we had that. It does not work with the steering wheel for controlling as far as I know. It is just a bluetooth receiver so that you can play things from your phone or other bluetooth devices. Hope that helps.
[ NATHAN  Feb 09, 2021 ]
I installed in HONDA PILOT 2008 with out navigation and the steering wheel controls worked fine
[ CESAR  Feb 06, 2021 ]
I have a 2008 Honda accord ex-l with xm radio. Instead of plugging unit to the back of radio, can I just plug in to the Xm unit in the trunk? Just like the USASPEC HON3. I
[ Joe  Jan 03, 2021 ]

This is designed to plug into the 14 pin port on a radio and no where else. You will need to work in the dash as Art mentioned. We typically have MasterSheets for vehicles which show how to remove the stock radio so this can be installed to the back of it. Those MasterSheets come free with the purchase
[ Paul  Jan 17, 2021 ]  Staff
I have installed 3 of these units into the dash of three different Hondas. All work perfectly. Putting it in the trunk would be much easier if there was the appropriate port. I never tried that. What I can tell you is that taking the dash apart is so much easier than it seems.
[ ART  Jan 13, 2021 ]
I have a 2011 Honda Accord EXL, dual climate control, no navigation, with subwoofer. Will this device cause the Handsfree Link Bluetooth for calls that the car currently has to stop working? Or will it just change over when I get a call?
[ Angel  Jul 23, 2020 ]
1 answer
This device does not stop the stock system from functioning so it will be there and can still be used even with this installed. Phones typically only connect to one Bluetooth device at a time making you choose to either have it paired to this device or the stock Bluetooth; not both.
[ Paul  Aug 09, 2020 ]  Staff
Will this allow me to pay music off of a USB flash drive? How would I navigate through folders or can you only go to next/previous song? Would I lose steering wheel controls? I have an 05 Acura TL without navi if that matters
[ Ryan  Mar 17, 2019 ]
2 answers
So all this does is connect to your phone through Bluetooth so you can play your music. You can still use your volume on the steering wheel.
[ Radhames De La  Mar 22, 2019 ]
I have only used the BT so far on my phone without fail. I have never tried the USB hookup, it just seems faster with the phone and google assistant, you can just tell your phone what to play, hope this helps.
[ Steven  Mar 22, 2019 ]
Can I play music off of a USB flash drive loaded with music? Will the steering wheel controls still work? How is folder selection done?
[ Ryan  Mar 17, 2019 ]
2 answers
The ability to retain steering wheel controls with aftermarket receivers will be determined by the receiver you are using and the vehicle you have. For full information on this type of integration (including the parts you will need) please contact an Advisor by phone (1-800-324-9695) or online chat.
[ Krissy  Mar 22, 2019 ]  Staff
No you can't do any of that. I bought this for my Accord and the only thing that worked as far as steering wheel controls were the volume controls. You cant switch songs from radio, or steering wheel, it has to be all from the phone or device you're connected from. It's the worst Bluetooth device you can buy. It disconnects every 5 minutes and reconnects and doesn't want to work half the time. Stay far away from this. It was a waste of money.

I have a XM portable radio i plug in to Aux now. If i use bluetooth(phone) and aux(xm radio) will one override the other? turn off the radio while phone is connected and vice versa?
[ David  Oct 21, 2018 ]
1 answer
If radio is on and you plug in aux it overrides the Bluetooth. Note if you leave aux plugged in and turn off radio the next time you turn on radio you will need to unplug aux cord and plug back in for it to work.

Do steering wheel controls for music playback (skip/repeat/previous track) work in Bluetooth mode?
[ Saami  May 13, 2018 ]
3 answers
The display on the radio changes, but does not control tracks.
[ Alan  May 14, 2018 ]
Yes. They aren't perfect but good enough.
[ Jeff Corbin  May 14, 2018 ]
I use a Pixel2 phone, and play downloaded music with the Amazon Music App through the Crux Bluetooth device installed in a 2004 Honda Accord. I do have steering wheel audio controls, but they do not work if the phone is sending music either via Bluetooth or via 3.5 mm jack. Therefore I have to select albums and tracks at the phone rather than from the steering wheel. The Crutchfield description says that you can control tracks, etc. only if the audio source is connected to the Crux device using the USB connection. However, I have not been able to get my Pixel2 phone to work at all with the USB connection to the Crux device. I don't know if the problem is my phone, or the Amazon Music App, or something wrong with the Crux device. I do have a 2018 Honda CRV which has USB input to the car's sound system. My Pixel2 and Amazon Music work perfectly in that car... I can control the who phone from the car's screen and/or steering wheel controls. So my phone definitely works with Android Auto App and a USB connection to a 2018 Honda car system. So something is not right about the USB connection between my phone and my Crux device.

[ Saami  May 13, 2018 ]

No the steering wheel controls do not work with this adapter.
[ DANIEL  May 14, 2018 ]
Does this work if I don't have the steering wheel radio controls or the in dash 6 disc changer? Do those have anything to do with the 14-pin CD changer port? I have a 2007 Honda Accord - 4 cylinder if that helps. Is there any way to find out if I have a 14-pin CD changer without pulling the factory stereo out? Thanks!
[ Steph  Apr 25, 2018 ]
1 answer
If your factory stereo has CD changer controls, it would have buttons labeled "Disc +" & "Disc -". They would commonly be radio preset buttons 5 & 6. You do not have to have factory steering wheel radio controls to use the adapter.

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

What microphone is this using to support the calls? Are you still reliant on the phone mic? I don't see anything about that.
[ Jacqueline  Dec 30, 2016 ]
1 answer
There is not a separate mic that comes with this Crux Bluetooth adapter. It does rely on the mic in the phone being connected. The BTS-HN2 does include a nice, magnetic phone holder that allows for hands free phone use without requiring any permanent installation.
[ William G.  Jan 01, 2017 ]
Will this system work if the CD player is not functioning on my accord 07? Part of the reason Im looking for this BT addition is because my CD player will no longer turns on and all Im left with is FM radio. However, watching youtube installation videos, it sounds like I may need the CD player function/buttons to turn on or use this BT set?
[ lauren  Dec 21, 2016 ]
1 answer
If the CD/AUX button does not work then this unit may not work, however if the malfunction is not the button itself the unit will work. Also be sure your car has the 14 pin connector on the back or bottom of the stereo. If you suspect it is the button you can always get an fm transmitter Bluetooth receiver that will broadcast to your fm stereo,you will suffer a little sound quality but it's very simple to use and does not require disassembly of your dash. I hope this helps, good luck Lauren!

Does this allow you to keep using you stock CD changer or does it replace that option?

After you install this, you can no longer use the factory CD changer.
[ Subramanian  Jan 01, 2017 ]
No my cds are not working now
[ Dipesh  Dec 17, 2016 ]
The in-dash CD changer is still able to be used. Apparently there was an optional CD changer that just plugged into the bottom of the factory stereo (why anyone would need that many discs is beyond me). To switch between the Bluetooth and in-dash CD changer just hit the CD/Aux button, just like switching from AM/FM bands.
[ William  Dec 14, 2016 ]
Yes, The stock CD changer is not affected and works perfectly with the Bluetooth interface
[ Jeffrey  Dec 14, 2016 ]
If You Have The CD Changer it would have to be Disconnected,The In Dash CD will still work
[ Gordon  Dec 14, 2016 ]
I installed it on my stock radio in my Honda Accord '07. It's a great choice for adding Bluetooth, USB, and AUX capabilities to your stock radio if it doesn't have them already. It integrates seamlessly.
[ Patrick  Dec 14, 2016 ]
For our 2008 Honda Fit it uses the only port available for the CD changer, so you can't use botg. But it may be possible depending on your make and midel. Recommend calling Crutchfield and inquire. They're great folks to deal with.
[ John  Dec 14, 2016 ]
I dont use cds anymore but i dont see why it would interfere with it. The port that this goes into was being used by sirius xm radio so I did lose that but installing this bluetooth device is much more useful to me anyhow.
