Works great! It plugged right in to my 2006 Audi A3 Concert radio. I couldn't have figured out how to install this interface without Crutchfield's excellent customer service though.

Great Vendor Support

Aaron from Robbinsville on 6/25/2019

2001 Audi TT

Verified customer (What's this?)
Verified employee purchase (What's this?)

So this was listed as "not fitting" with my Audi TT, and I reached out to the manufacturer to see if I could try to hardwire it anyway. They had me take some photos, and informed me that it had an adapter and would fit no problem. Once I got the radio out it installed in about 10 minutes and worked like a charm. I've only had a week, so we will see the long term reliability, but the support and installation was great!

'03 Beetle with Bluetooth

Crutchfield customer from Allen Park, MI on 6/2/2019

2003 Volkswagen Beetle

Verified customer (What's this?)
Verified employee purchase (What's this?)

Love the Bluetooth connection. Installed in a little cubby next to the manual in my glove compartment. So intuitive and easy to use. Press the CD button on the factory Monsoon radio and the unit powers up. Select it on my phone and play anything I like. An awesome addition to my 16 year old diesel VW that gets 50 mpg.

Pros: Works and plays well with factory radio.

Cons: I get random beeps and momentary "gaps" while playing. Can be distracting. Don't know if it's the phone, BTS-VW1 or the radio. Finding ground in the Beetle took 18" of wire soldered to the provided ground wire with the unit.

Crux BTS-VW1 Bluetooth Interface

Crutchfield customer from Earlysville, VA on 2/15/2018

2007 Audi A3

Verified customer (What's this?)
Verified employee purchase (What's this?)

I installed this in a 2007 Audi A3. During 2007, Audi changed from the 8 pin CD changer connector to the 12 pin connector. I pulled my radio and found that it had 8 pins so I got the 8 pin version. It worked as advertised and took only a few minutes to install: pull the radio out using the pulling keys, plug the interface in, find a screw for the ground wire push the module down behind the dash, and push the radio back in. My only reason for 4 stars instead of 5 is that one time when I started my car, the CRUX did not fire up for some reason. Shutting off the car and restarting fixed it. Not sure if this means I'll have problems down the road but so far so good. The other thing is that it makes an audio announcement when it connects with my phone and the announcement is a bit annoying - better if it could push some text to the radio but I suspect this is a problem. In any case, the phone shows the connection. If I could turn the announcement off, I would.

Returned item after calling tech support and being told it wouldn't work with my 2001 Audi A6 with a Bose Symphony Radio even though the website said it would. I saw an adapter plug on the site that I thought may make it work but the tech said there were no adapters. Very disappointed.

Very easy install. Comes with manufacturers number if you have issues. Your old head unit becomes a new one.

Pros: Easy install.

Cons: Can't connect line and Bluetooth at the same time.

Breeze to install

Katherine from Troy, MI on 10/22/2017

2000 Volkswagen Passat

Verified customer (What's this?)
Verified employee purchase (What's this?)

Installation was a breeze. Figuring out how to control it, not so much! I strongly recommend going for the A pillar ground. I tried a couple of different ground points and none were as stable and led to some funky BT behaviour. The USB reader will read .mp3 and .wav files only. Remove all stray Apple forks and files from the USB stick as these appear to confuse the reader. Folders do not seem to have any bearing on what actually plays - ie naming a folder CD1 or 1 does not seem to equate to CD1 on the HU. I have yet to elucidate what controls the play order. My track up/down buttons do not do anything, but repeated presses of the CD# buttons will cause a track change. I can switch from BT to USB by pressing the scan button on my HU. Despite these issues, this is a solid upgrade for an old stock HU and at the price point, a total no-brainer. I recommend to anyone who is looking to replace their dead CD changer or just have modern audio functionality in their car. If a new unit with phone functionality comes out, I will be first in line for it!

Pros: Installation, price, functionality

Cons: Learning curve for this digital audio file noob

BTS-VW1 in '06 Beetle/Monsoon: Crux(trated)

DenCon509 from Ellensburg, WA on 4/2/2017

2006 Volkswagen Beetle

Verified customer (What's this?)
Verified employee purchase (What's this?)

The AUX audio input on my Beetle had been damaged by a previous owner and was not usable. The dealer wanted ridiculous $$$ to repair it and this is not a simple DIY fix (unless you like dismantling your dash - no easy task on Beetles). Bluetooth: Yep - does the job handily. USB: Plays music from USB memory stick only, doesn't produce enough power to charge my Android phone. Aux: Works, but get faint background hiss. I have a call in to Crux tech support for deeper answers/solutions, but I think this device has limitations. Still, you really cannot beat the value - keeping the stock radio is the best anti-theft feature and you don't have to look at the ugly installation panel with an aftermarket head unit. With some good double-stick tape, you can affix it to the underside of your lower dash (don't cover up the screws!) for a tidy look; or you can just set it in the underdash tray/cupholder. UPDATED 5/8/17: I returned the first one due to troubled USB functionalities; mfr thought it was defective, the second one is no different. The mfr's tech support is slow to respond, but at least they tried to help. Important technical information is nonexistent, I learned from their Tier 2 support that it only supports MP3 (even that didn't work), they couldn't tell me which version Bluetooth was running. There is no way to update firmware or diagnose problems. USB is basically useless - doesn't play memory stick or phone storage music, not enough power to charge. Bluetooth stutters/stammers like mad at times, sometimes just goes silent. One particularly annoying feature: when I have a USB device connected, Bluetooth hijacks the connection, disabling USB media play. I have used my phone with other vehicles, I know that my BT is flawless. AUX is fair, but brings with it a little hiss that can be overcome by turning up source volume. Sadly, I have to say goodbye to this stealthy solution and return it for a new HU (head unit). Thanks to Crutchfield's stellar customer support and patience, I'm stepping up to a nice digital media receiver for a little more $$$ and a LOT less frustration.

Pros: Huge Plus: Leaves stock stereo in place - a nice theft deterrent (no one wants to steal a VW stereo!). Can't be beat the price. You give up the CD changer (if you have one), but all other stock functions remain. Easy installation - simply replace the CD changer portion of the modular plug with supplied harness plug, ground to stock radio chassis and you're done. Plenty of cable to afford flexible location. UPDATED 5/8/17: Save feeding the cable up through the dash, installation is a snap. Stealthy - leaves stock HU in place, great theft deterrent! Bluetooth pairing is quick. Kudos to Crutchfield's customer service (and patience).

Cons: Cannot charge while using Bluetooth (automatically switches off - no override - have to charge separately). USB only plays music from USB memory stick - not from Android phone (regardless of settings/tweaks). Aux produces faint background hiss. Charging function doesn't charge my LG V20 adequately - cannot keep up with use. UPDATED 5/8/17: Bluetooth stutters, stammers and stalls, often disconnects without reason. Aux a little hissy. No technical device data provided. Mfr. tech support tries, but not very helpful.

Affordable upgrade for Bluetooth; may need cable splitter for Bose

Jeremy from Portland, OR on 2/21/2017

2004 Audi A4

Verified customer (What's this?)
Verified employee purchase (What's this?)

My 2004 Audi A4 Avant, that this was installed in, has the stock Symphony II radio with the Bose upgrade. I believe the Bose upgrade portion is what caused an "incompatibility" issue that I faced. In order to connect the Crux to my radio, I had to not only remove the "CD changer" wires, but also some other wires that are part of the same 20-pin connector (coming out of the vehicle). Some of the wires that were removed were "line outs", connecting the radio to the Bose amp in the back, so this resulted in no sound coming from the speakers, even when a different source like FM radio was used. I got this Crux unit working once I put a 3rd party "splitter" in place, which converts the 20-pin connector to 3 separate connectors (one for "CD changer", one for the "line outs", and whatever the 3rd one is for). I was then able to connect the Crux to the CD changer port, and still keep the other wires connected. Summary: If your vehicle has a "solid piece of plastic with 20 pins" connector, that connects to the top of the radio, and the Crux seems to be working (blue LED; it can be discovered via Bluetooth), but there's no sound, you MAY need this splitter. Note, however, simply having this 20-pin connector does not necessarily mean the splitter is required. If you have an 8-pin connector just underneath (-/+ to the speakers; my car does NOT have this), you're probably without the splitter, but I can't say for sure.

Pros: Inexpensive, compared to other products. Bluetooth has been 100% reliable so far. Ships with cell phone car mount.

Cons: May required 3rd party splitter for certain vehicles / sound systems.

Product Research

Features

Add-On Bluetooth/USB/Aux Interface Adapter: The Crux BeeLine series BTS-VW1 allows you to add Bluetooth music streaming, USB music playback & charging, as well as a 3.5mm Aux input to the factory radio of select Audi & Volkswagen vehicles.

Vehicle Compatibility: The Crux BeeLine series BTS-VW1 is compatible with select 1998-2008 Audi & Volkswagen vehicles that feature a factory radio with an 8-pin CD changer port.

Make Model Year
Audi A2 1999-2005
A3 2001-2006
A4/S4 1998-2006
A6/S6 2001-2004
A8/S8 1998-2003
Volkswagen Beetle 1999-2008
Golf 1998-2006
Jetta 1999-2008
Passat 1999-2006

Notes:

  • Factory radio must have an 8-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 navigation radios.

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-VW1 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/Folder 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-VW1 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-VW1 features an attached 30" harness which plugs into the 8-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 8-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-VW1 is accessed through the "CD" button on your vehicle's factory radio. In this mode the factory radio will display "CD1 TRACK1". You cannot manually switch between the inputs of the BTS-VW1. Instead, the BTS-VW1 automatically switches for you based on what device you have connected - Bluetooth, USB, or Aux (only connect one device at a time).

Q
Will this also allow me to answer phone calls hands free?
[ KATHY  Apr 23, 2017 ]
7 answers
A
No, this system does not accommodate hands free phone calls. However the music does shut off when a call comes in.
[ Corinna  May 11, 2017 ]
A
I don't think so. There is an aux port which I wondered might allow it if a mic was hooked up.
[ Shad  May 02, 2017 ]
A
No, it only functions as a bluetooth receiver. Doesn't have any kind of mic.
[ Michael  May 01, 2017 ]
A
No, it won't. Your phone has two different Bluetooth connections: One for phone calls and one for media. This device only connects to the media Bluetooth for playing all your music from the phone or tablet through the car stereo. It does not have a microphone to be able to use it for phone calls.
[ Brian  Apr 25, 2017 ]
A
No, it will only allow you to hear your caller through the radio, but you will still be using the phone for the microphone.
[ Dennis  Apr 24, 2017 ]
A
No, it won't let you answer phone calls hands free. It momentarily disconnects from the car during the phone call and then reconnects after the call. Hands free devices come with a microphone. This one doesn't have one. I also looked at the manual again and it doesn't show any hands free features. Good luck with your search.
[ John  Apr 24, 2017 ]
A
I do not know. My phone syncs with both the radio unit to stream what's on the phone and a Garmin GOS device for phone calls. When the phone rings it does prioritize the phone call and temporarily suspends streaming to the radio. When the call ends the radio streaming automatically resumes. If only the radio Bluetooth were used I do not know how phone calls would be handled.
