Install the included external microphone in a good spot for the best reception, such as near your visor or on top of the steering wheel column. You can also adjust the microphone volume so your callers can hear you clearly. The Crux interface allows you to pair up to eight Bluetooth-equipped phones simultaneously, so other drivers and passengers can use their phones as well.

Tunes served up wirelessly

In between calls, you'll need something to occupy your drive time. The Crux BEEBG-33 interface also lets you listen to your favorite music wirelessly from your compatible phone via Bluetooth. And if any calls come in, your music will be be muted so you can hear your caller on your factory speakers. Turn it on, turn it up, and enjoy.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this interface is compatible with your vehicle.

Important note: This interface routes phone calls and streaming music through your vehicle's front speakers only. You'll have to access the rear of your radio to install this Bluetooth adapter. You can check out a step-by-step description of the process in the adapter's manual.

Note: Not compatible with 2012-up Chevy Avalanche/Silverado/Suburban/Tahoe and GMC Sierra/Yukon vehicles that are equipped with factory-installed navigation radios.

Multi-Device Pairing: The CRUX BEEBG-33 pairs with the vast majority of Bluetooth-enabled mobile phones (including iPhone, Android, Blackberry, Windows, etc.). You can pair up to 8 mobile devices with the BEEBG-33, however only one device can be used at a time. Once paired, the BEEBG-33 will automatically connect with your mobile device when in range (up to 30').

Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with The CRUX BEEBG-33.

Hands-Free Phone Communication w/ External Mic + Voice Dial: The CRUX BEEBG-33 supports Bluetooth profile HFP for wireless hands-free phone communication. With the BEEBG-33 installed in your vehicle, you are able to answer and end call using the vehicle's factory steering wheel controls. The factory radio automatically mutes any audio source as soon as a call is received and announces the caller's name and number through the front speakers; your previous audio source resumes when the call is ended. You can activate the voice dial function of your phone through your vehicle's steering wheel control in order to make a call (otherwise you will need to use your mobile phone to make a call). The included external microphone carries on your side of the conversation, while the other party is heard through your vehicle's front speakers. DSP and Echo-Cancellation allows for clear conversations on both sides of the phone call. Other features that can be accessed from your vehicle's steering wheel controls are Privacy Mode & Call Waiting.

  • There are no hands-free phone control functions on the factory radio. Phone calls need to be answered/ended from the factory steering wheel controls, phone calls can be made via voice control, and volume is handled by the factory steering wheel control.
  • If an incoming call is answered from the mobile phone's keypad, the call will direct itself to the headset on the mobile phone. To re-direct the phone call to the Beeline interface and factory audio system, it must be done directly from the mobile phone.
  • When transferring a phone call to the mobile phone for privacy, the user must re-connect the Beeline Bluetooth interface and the mobile phone by selecting the module from the device menu on the phone.
  • The Bluetooth interface will disconnect from the mobile phone as soon as the key hits the off position. Then the call will be transferred to the mobile phone.
  • For vehicles with factory backup sensors, while a call is active the sensors will not be heard. Please end the call to retain sensor audio.

Wireless Music Streaming: The CRUX BEEBG-33 supports Bluetooth profile A2DP for wireless music streaming. This means you can wirelessly stream stored music and music apps from your Bluetooth-enabled mobile phone to the Beeline interface and your factory stereo. Audio is only heard through your vehicle's front speakers. The factory radio offers no music control or song/artist display. All music browsing and song/artist information is still done from your mobile phone.

  • The steering wheel controls will only adjust the gain of the Beeline Bluetooth interface. The volume knob on the factory radio will remain the master volume control after you set the interface's gain to match the volume output level of the other sources.
  • When using an iPhone, you may encounter pauses (up to 8 seconds) while using music applications.
  • For vehicles with factory backup sensors, while music is playing the sensors will not be heard. Please stop music playback to retain sensor audio.

Siri Voice Commands: The CRUX BEEBG-33 supports Siri voice commands for iPhone 4S & 5 (running iOS 6.1.3 or earlier). Siri can be activated from your vehicle's factory radio or steering wheel controls. You can then communicate with Siri through the Beeline Bluetooth interface's external microphone and your vehicle's front speakers.

Note: Siri voice commands may not respond properly with newer iPhone devices running iOS 7 and up. Standard voice command functions may have to be used instead.

OnStar Retention: Once the factory audio system is connected to the Beeline series Bluetooth interface, your vehicle's factory OnStar feature will only work when using the OnStar button on the rear-view mirror. To use your vehicle's steering wheel OnStar button, you must wait for the Bluetooth interface to enter standby mode with not activity between it, your mobile phone, and the vehicle's factory audio system.

Installation & Mounting Options: The CRUX BEEBG-33 installs behind your vehicle's factory radio. The cable of the factory radio gets unplugged and the included T-harness takes it place on back of the radio. Then the factory cable plugs into the T-harness and the T-harness into the interface module. There is also a power/ground harness which plugs into the interface module and the external mic's attached cable. The external mic comes with a sun-visor clip and a self-adhesive bracket for mounting purposes.

I have a 1996 gmc serria.. is there a way that I can install Bluetooth?

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.

I bought a Crux BEEBG-33 interface for my sons Saturn, and it took about 20 minutes to install and is all in the dash. Just make sure that they have one that fits your vehicle. My sons S10, they did not make one for his so just put in a stereo with bluetooth. His costed $60 on Crutchfields and they included the wiring harness and step by step installation instructions.
[ DAVID  Mar 30, 2018 ]
On a 2007 Chevrolet Avalanche, is it true that Bluetooth audio streaming only plays out of the front speakers?

I have a 2012 but what i think your thinking of that the voice command is for bluetooth is heard through the front right speaker.... your audio VIA BLUETOOTH should be heard through the whole truck...i returned my Crux cause it wasn't compatible w my Navigation system...

[ PATRICK  Jan 04, 2017 ]
I believe that is likely true on your car, as I have a 2010 Chevy Impala and it has the Bose system with hands free Onstar and put this BEEBG in and while streaming audio none of the car audio head controls work. I can adjust volume on the steering wheel of the car up and down or the smart phone { mine is an Android} and it streams beautifully but no back speakers. It is best to use the wheel cuz the phone will tend to blast you out of the car if you do it that way. But in all my usage the front speks were enough, could be I'm an old burnt out audiophile and i don't care.
[ LEIGH  Jan 04, 2017 ]
Does this unit display the call info. Or will the radio be hands free when you dial the call?

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.
[ KRISTINA  Oct 16, 2015 ]  Staff
Front speakers only is a deal breaker! Perhaps while on a phone call that's okay but play music all speakers is a must. IS there any other option for music on all speakers?
[ Jeffrey  Aug 11, 2015 ]

Plays on all speakers via Bluetooth in my Honda Pilot. Maybe a switch setting problem?
[ Scott  Jun 21, 2016 ]
From the radioit will play from all speakers. If you are feeding music via Bluetooth it will only play front speakers. I'm unaware of a fix for this.
