Terrible connection time.

Great to have Bluetooth but takes forever to connect once paired. Wish it was better for the price as I could get a good head unit for not much more. Wish it would connect quicker is my only complaint.

I had to unplug XM module or the preview channel would take over. Connects easy and good sound for music. If someone calls while not listining to phone goes to Bluetooth but radio does not automatically switch to Bluetooth. You still have to dial through phone to make call.

Great product, super easy install, works exactly as expected. Happy to finally have Bluetooth in my car thanks to this handy little device!

A whole lot better than nothing

The install was pretty easy. Just remember that there should be room for all the extra wires below the stereo unit since the climate controls don't fill up all of that space. Running the microphone wire took the most time. As other reviewers said, yes it makes loud beeps and such and there are functionalities that I have in a newer vehicle that I wish this had but overall it's vastly better than no Bluetooth at all.

Better than nothing I guess; frustrating

Exceedingly difficult to make a Bluetooth connection. I tried repositioning, calling Crux tech support, reseating the circuit board as they suggested, etc. It now will connect sometimes after a few minutes, but I usually must turn on and off the stereo and on and off Bluetooth in my iPhone 14 Pro phone. It's not worth the effort for short trips around town. I'll be purchasing a full stereo now instead. If you need this solution, it's better than nothing if you're driving longer distances.

Not perfect, but you get what you pay for. Overall, not bad.

For the cost, this's a pretty valuable product. There are some flaws here that are a trade off for the price. Pros and cons below. This was installed on a 2010 GMC Seirra Denali with factory Bose, Onstar, and XM. The main thing I distain bout the factory stereo is no Bluetooth connectivity. I was sick of replacing BT FM tranmitters/BT aux converters, but didn't want to spend the cash to replace the head unit. Cheapest option I found to tie everything together was over 600 bucks which didn't make sense to me for what I wanted. The good- Installation was super easy, and took me less then a half hour to install. I watched a video on how to do it, but could have figured it out from the directions Crutchfield provided easily. Basically plug and play, and run a microphone up to the rear view mirror area for phone calls. Sound quality is pretty good, but I lose audio quality if you crank up your Bluetooth volume. If you are a audiophile and want to pump your music loud, just buy a new head unit. I can still access factory XM, which I thought I would lose. Super cool! Steering wheel controls now work with with my phone once it's connected. The bad- This thing takes a while to pair with your phone, and isn't consistent with the pairing time. Somewhere between 30 seconds and 2 minutes. This is SUPER annoying as it it plays annoying loud tones as it starts up. If you do a lot of engine start / stops drivin

Horrible Connectivity

This unit is HORRIBLE to connect to. Android or Apple. Auto reconnect is spotty at best. Sometimes takes more than a mile down the road to connect...sometimes won't connect at all. Manual connection is just as bad. Audio quality is fine as long as you don't have phone volume on maximum. Steering wheel controls work fine. Microphone is mediocre but not bad. All of the good is really outweighed by how difficult and inconsistent the connectivity is.

CRUX BTGM-33 Bluetooth Interface

This was installed in a 2009 Chevy Suburban Ltz w/ nav and xm. Very easy to install. Hardest part was running the wire for the microphone. It took less than 30 minutes to complete the install. Sound quality and microphone quality are amazing.. Now my only complaint..each time you start the vehicle it beeps to let you know it's connected..the beep is extremely loud. I wish there was an adjustment to lower or turn off the connection tone. Also you loose xm radio to gain this Bluetooth feature since the device plugs in through the xm interface on the radio. This isn't a problem for me since I don't use xm radio. I stream my music through Bluetooth so this allows me to enjoy my music on this radio without having some gaudy external device plugged into my cigarette lighter taking up console space. I would give 5 stars if not for the loud beep and the loss of the xm function. But the sound quality and ease of installation far makes up for those issues. Great product..highly recommended if you want to keep your factory radio and add Bluetooth calls and streaming.

Installed this in a 2010 escalade, install instructions didn't match the stereo, but it still worked after a youtube vid on how to remove the headunit. Wish the module was smaller as it was a pain trying to get it and the wiring in just the right place to reinstall the head unit. Phone calls are clear, music sounds great! Only complaint is I have to turn the volume on my phone down, or it will distort the factory speakers in the truck. Once I figured that out, sounded great! Bluetooth connection was painless!

Amazing product

Works great with my 08 Chevy Tahoe LTZ. iPhone connects fine. You will need to close out the music app you are using and reopen it, or switch from xm to fm and back to XM when you turn the vehicle off and get back in but that is a small inconvenience for the ability to have Bluetooth and retain your steering wheel controls as well as the backup camera and stock head unit. For the price you cannot beat this product. 5 stars from me.

This thing was an huge help. I've been using FM transmitters for years. I just got a used car, circa 2008, with a factory DVD front & back and controls on the wheel. Didn't want to break the bank and risk losing anything. Now I have something almost as good as newer CarPlay unit. I would have given it the fifth star if it connected to the phone a little faster. One to two minutes on a long drive is nothing; my ride to work is three minutes.

Doesn't work

Does not work at all in my car! I have a 2008 Buick Lucerne, which is listed as a compatible car. I first bought and installed a new radio with XM satellite compatibility. Then, I installed the BTGM-33 according to the instructions. However, as soon as I turned on my car's engine, all sorts of functions failed (the radio wouldn't play, headlamps wouldn't turn on, turn signal didn't work, check engine light turned on, etc.). I called tech support, but they couldn't find the issue, so they sent me a new BTGM-33. I installed that one, and same exact problem. Thankfully, Crutchfield gave me a full refund, but I'm disappointed that their device didn't work, twice.

CRUX BTGM-33 Bluetooth Interface

I purchased this for a 2013 Chevy Avalanche and I have not regretted it. I learned a lot from the reviews before my purchase and will add my 2 cents. For those with Apple phones it can take up to two minutes to connect to the bluetooth interface. This is documented on either the Crux or Crutchfield websites. My Android phone connects immediately and every time. Another buyer mentioned that they keep their bluetooth volume on their phone at 3/4 loudness and that keeps the radio from blasting you when you disconnect from calls. This works well for me. I appreciated that tip. Others have mentioned how difficult it is to position the wiring and box behind the GM OEM radios with the built in Nav screen. I don't have that radio but I still had to rearrange the box and wiring several times before the radio slid back in fully. I installed the remote microphone at the front left corner of the overhead console and it works good there. Be prepared to spend a little time installing this system. Mine took about 45 minutes. However, the overall the installation went smoothly and the system operates as advertised.

It's a little finicky. Takes a minute or two to pair, not sure why. Once paired it works great. Can't get the steering wheel controls to work with it, but I rarely talk on the phone, so not a deal breaker. I just want to listen to podcasts mostly while I'm driving and it works great for that. Easy installation, half hour at the most.

Escalade installation is tricky.

Seemed like a pretty straightforward install and it was for the most part. But, when it came time to put the radio back in is when the fun started. The Escalade has a limited amount of space behind the radio and housing, therefore the plugs won't fit. Here is what I did. Pull the center speaker and the clock. This will give you the ability to help the wires through without crushing or breaking anything. First feed the module through the spot where the wire loom comes out of. Feed it to the driver's side and hang it over in front of the vent. Now start feeding when harness in to the space, holding the radio up and close, reach in to the speaker hole and pull the loom and the harness back into the dash. Keep pulling and tucking as you go. You will have to kneel on the passenger seat to get the right angle. Once it's in use some two sided tape to stick the module to the side of the housing under the vent location. Put it all back together and it works wonderful. If the kit were to have wires double the length it would not have been as hard to get installed cause you can tuck them and then pull them through. But all and all it's a nice kit with great sound!

Loss of handsfree calling capability!

Recently purchased the Bluetooth interface for our 2009 Chevy Tahoe due to GM changing over from a 2g to 5g on their handsfree calling. The change by GM resulted in the loss of handsfree calling and receiving communications with family members. The installation was easy with good instructions for each step of the process. I would recommend this for those who have lost their handsfree calling capability in their vehicles.

Just installed this today after having it a weeknand a half, truck was getting maintenance. So so far Im happy with it after only an hour after installing it.I installed this before my line out plug and play converter for my aftermarket amp and subs and as stated working so far. The only thing Im not certain of yet is if it is going to affect my back up sensor system as so far it is not working ,but after having the radio out for about 30 min it may just need a few on and off times to recalibrate, hopefully this is the case.

VERY HAPPY

I bought this system with low expectations. Due to some of the reviews. But praying for the best, I really like it. I haven't had any problems with it syncing with my radio. I bought for my 2008 chevy suburban with Bose system and steering wheel controls. The only thing is when you get a call you higher the volume and when you end the call the music is blasting! In my opinion it is worth the money. Just be very careful with the trim. The last thing anyone needs is to break a $75 trim. Highly recommend using plastic tools. And be very patient! At the end when you finish installing it and everything is working. Highly recommend taping the connections tightly so they don't loosen up and disconnect.

My suburban, came with the factory Bose system and was excellent, I was very happy with it but wanted a quality bluetooth interface for calls and streaming. This is a super simple user interface to install, it took me 5 minutes and I had never worked on my suburban until that point. Keeps the factory controls and updates the blue-tooth. Excellent sound quality on the microphone for high quality conversations. The streaming is excellent with no distortion. Great value for all the features offered.

Not usable

This product technically works, but has serious flaws that render it unusable. This is on my 2007 Escalade 1) My screen does not display song title/artist 2) When you turn the car off then back on, it does not automatically return to the bluetooth connection and reconnecting to my iPhone takes 15-20 seconds, despite the fact that the display says "Paired, Playing" the entire time... 3) When you activate bluetooth (which it has to do each time you start the car) it makes a long beep noise. Not that big of a deal except if you were listening to loud music when you turned the car off, then the beep noise will be VERY loud! It made me jump the first time it happened. 4) Audio is distorted, especially with the volume turned up on your phone. At max volume on your phone, it will be unbearable, but even at 75% phone volume, the audio is distorted at higher stereo volumes (no I'm not overdriving the system, same noise level on the FM radio and the sound is clear). This device was replacing a Carconnect iSimple bluetooth module that died after about 2 years. I was hoping this product would last longer but I'll never know because it's useless. The iSimple module had none of the issues noted above - it displayed the song title, connected instantly to known devices, didn't make any noises, and had no distortion at any phone volume. Looks like I will either switch back to another iSimple or replace the entire stereo....

Don't do it

Since installing this into my wife's 2007 Tahoe, many issues have been occurring with the vehicles BCM. Random radio shut off, items such as blinkers not synchronized on the dash to the actual lights, and buzzers in the vehicle not shutting off when we turn the car off. I plan to remove this as it was a total waste of money. I just wish I could return it and just move forward with replacing the radio as a whole. I wanted to keep the original radio as it has DVD, but this thing is more trouble than it's worth.

2008 Chevy suburban with Nav. It works. Make sure you plug the connectors in tight. I had a the plug that goes into the crux itself not quite snapped tight and it was causing some noise distortion. Another thing is I've had to turn my bass all the way down when playing blue tooth music for it not to distort, but it sounds perfect after doing that.

I bought this for my 07 Tahoe I just got. Installation took awhile, but most that was removing the radio bezel and taking interior trims off and on to run the mic cord.

The problem came with putting the head unit back in, there isn't really space for the crux unit behind the head unit. It took me over a hour and lots of choice words to finally get the head unit back in place. As far as the functionality- it works good once connected, it doesn't like to re-connect very well if you are in and out of the vehicle very often, and when it connects it makes a god awful tone.. but once connected the music quality is perfect, I am overall satisfied with it

Crux BTGM-33 06 Impala Bluetooth Interface

Installed in my daughters 2006 Impala LT with XM/Onstar. Works Great... Note to self read the directions and follow them... I didn't think it worked when I first tried it, Had no XM, glanced at the directions but didn't follow them to the letter. After reviewing them I followed the advice given and wow works like a charm, Phone, Streaming Audio, and XM. On test calls had great feedback on audio quality. Using it with a Moto Force Z2, and a Apple Iphone.

Works great, connects quickly to the phone and the sound is perfect. It's nice to be able to use the steering wheel buttons to answer the phone. Only wish after the call ends that it automatically goes back to stereo.

Great buy works great in my Escalade Only thing is that I had to take it out the case because it wouldn't fit behind my radio ( wrap it with duck tape duck tape to make it thinner fit right in )!

Installed two of these today. One was in an 08 Tahoe and one was in an 08 Yukon. They work flawlessly and as if the bluetooth was a factory part of the system. Great job Crux on a great product.

Works great as advertised!

I installed the new interface in my 2008 Chevrolet Impala LTZ with a factory Bose/SirrusXM head unit. After using it for several weeks, it continues to connect with my iPhone and plays my music flawlessly. I also have been able to receive calls and terminate calls via the buttons on my steering wheel. I'm successful in making calls using the CRUX interface mike in combination with SIRI on my iPhone. I'm also able to switch between SirrusXM and my iPhone via the steering wheel 'source" button. The only drawback I see is the radio does not display what song or who the artist is during play back. I located the CRUX microphone next to my rear view mirror and then tucked the microphone wire in behind the leading edge of the headliner. I made loops periodically in the wire so it would not pop out of the headliner, then feed the wire behind the A pillar and under the driver's side dash. I removed under the under dash plastic trim and a metal plate in order to route the microphone wire to an opening behind the radio head unit. I tucked the CRUX control box behind the glove box and left the remaining wires below the radio head unit (Note: I also removed the ac/heater control unit). The new wires and connections did not interfere with the re-installation radio head unit.

Crux BTGM-33

Works great. My only complaint is that when making a call it sits in silence until the other party on the phone picks up. There is no ringing on my end. So then I wonder if the call if going through or not. There is also a whine that I hear when listening to The XM.

Great buy

The best option to add Bluetooth to the stock unit. Steam quality is great. The voice audio is surprising really good for the caller on the other end. As good as I've ever heard for car hands free.

2007 Cadillac Escalade EXT. It took me about an hour and it was up and running. Works AOK and I still have XM!. Too bad it could not hook up to the microphone already in the truck, but I hid the separate one and everyone says it sounds very good. I would buy this again.

Misleading Advertising by Crux

Crux needs to rewrite their product capabilities. They mislead the buyer into believing that the product will work with their vehicles. Fortunately, Tim (service), was able to track down the cause of the malfunction. My problem wasn't with Crutchfield, but rather Crux.

2007 Silverado Easy installation,and my iPhone paired right up. Streams well. A little slow hooking back up after turning truck off and restarting. Only draw back for me is that when you are streaming or playing Am or Fm the volume for answering the phone is very low compared to the volume you were listening to so you have to turn up the volume when talking on phone. Other than that wors well.

Crazy experience with Crux tech support!!! Beware DTS owners!

First off, Crutchfield is great and let me return this product no questions asked. My car is a 2011 Cadillac DTS premium with Bose. I had the most bizarre experience with this product. I hooked it all up according to the (minimalist) instructions and got nothing. So I called Crux customer support. I was told the tech advisors are busy and I would get a call back in 5 minutes. After 1 hour I called back. The tech asked if I had everything setup right and I told him I did and asked if I could just remove the XM radio harness and use that input alone, he said sure, seeming quite disinterested in my troubles. Then out of nowhere he says "did your gauges start flashing and then the car wouldn't start?" Needless to say I was flabbergasted! I said "no, why?". He indicates they are working out some bugs with this product for my particular vehicle and they had some reports of the aforementioned issues. He then tells me "give me your phone number and I will call you when this is fixed". Rather than waiting for that option, I immediately returned the product to the store (again, where the Crutchfield team was awesome). I just can't believe that this seemingly devastating issue is not addressed on the Crux packaging or the Crutchfield website. Thank god simple non-functionality was the only problem I encountered.
