Overview

Our take on the Metra VT-GMRC-01 Wiring Interface

Problem: Installing an aftermarket receiver in many late model GM vehicles means losing the chime that warns the door is open, along with audible safety warnings.

Problem: Installing an aftermarket receiver in many late model GM vehicles means losing the chime that warns the door is open, along with audible safety warnings.

Solution: Metra's VT-GMRC-01 GM Class II Data Bus Interface lets you replace the factory receiver in these vehicles and keep the door chime and all audible safety warnings.

Hook the VT-GMRC-01 to your aftermarket radio, mount the module in a location where the chime can be heard, and plug it into the existing factory plug. Get the great sound you want, and keep all important safety features intact. The VT-GMRC-01 will not work with OnStar equipped vehicles. 1-year warranty.

Important Note: Because your vehicle is factory-equipped with a special sound system, you will need to purchase this VT-GMRC-01 interface in order to keep your factory door chime (needed to keep audible safety warnings functioning) while providing a switched 12-volt power source for your new radio. If you do not use a compatible interface when you replace your factory radio, you will disable the audible warning system in your vehicle. Crutchfield cannot provide a free wiring harness for your vehicle, and we strongly recommend that you use the recommended interface when replacing this vehicle's factory radio. Failure to do so may result in serious injury or death.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

Wyatt from Phoenix, AZ on 9/10/2014

2005 Chevrolet Silverado 2500/3500
Crutchfield Customer Review (What's this?)

Product works as described, other reviews are correct, it is very loud even after breaking the board connection to quiet it down. I muffled it some with some foam and almost sounds factory now. Did have a problem initially because the unit fed power back through the accessory wire making the vehicle think it was still powered up on accessory. Worked fine after installing an inline diode.

Pros: Great option to keep factory chime.

Cons: Loud but would rather have that then to quiet, can always muffle it. Power leaks back through accessory lead.

Wired wrong but easy to fix and works great.

2005 GMC Sierra 1500
Crutchfield Customer Review (What's this?)

This device was wired wrong for my 2005 GMC Sierra Crew Cab w/o Bose or Onstar but it was an easy fix and is working great. The pink data wire was in the wrong spot on the connector. When I initially plugged it in it dinged 5 times, the time displayed on the radio for 5 seconds then went blank. I tried to turn the ignition key off and back on but nothing worked at that point. I could recreate the problem by unplugging the Metra unit and plugging it back in. Tech Support walked me through where the wire should go and I moved it. It's one of those mini multi-tabbed female connector pins so I wasn't able to get it out. I had to carefully cut the connector to get it out but I'm ok with that. This wasn't a big deal, but I wanted to mention it in case anyone else runs in to this problem. It may have just been that one unit that was wired wrong, I don't know. But Crutchfield Tech Support was great in helping me with it. And they asked me if I wanted a new unit instead of changing the wire position. Can't ask for more than that. Even with the tracing cut to lower the volume it's too loud so put some electrical tape around it to cover the sound holes in the case. It wasn't that bad when I tested it outside of the dash and I thought that being inside the dash would lower the volume of it, but it actually made it louder. I would have given it 5 Stars if not for the pin placement problem.

Pros: It works as described.

Cons: Had to change a wire position in the connector.

Crutchfield Customer Review (What's this?)

I was a little disappointed with this unit. It works fine and does the job but had to tape it together ..the case wouldn't stay snapped together. and omg it is loud! The instructions tell how to cut a circuit on the board to lower the volume but you have to take everything back apart to make the adjustment.

Pros: does the job ... chimes work like factory did

Cons: just feels clunky and kinda cheap loud ..really load..lol instructions left a little to be desired

Good Interface.

Plugs were exact match but wiring instructions need to be reviewed for completeness.

Pros: Plugs did match existing wiring with no problem.

Cons: instructions/color code was not as good as some I have seen, but was able to make it work first time

Don't install without it!!!!

Jesse from Bath PA on 8/4/2014

2002 Pontiac Sunfire
Crutchfield Customer Review (What's this?)

This little baby made life a whole heck of a lot easier!!! Its so much nicer to have a separate chime instead of playing the chime through you car speakers.

Pros: Compact for easy placement Length of wires is good Super loud, so try aiming into your dash, not out from it, and it also has the ability to lessen the volume but only by opening the unit and cutting a solder point. I recommend holding off on that step unless you absolutely need to.

Cons: Had a wiring issues, was told its a typo on the directions, but ended up splicing the power antenna (from harness) wire to my amp remote (from sub) and power antenna wire (from radio) to make it work properly. solved my issue.

No luck with this adapter

Crutchfield Customer Review (What's this?)

Easy to install, a little loud, but better than nothing. The problem is maybe the quality, chimes when it feels, sometimes chimes when no supposed to do it. I little disappointed with the adapter, since is a process removing from behind the radio for return it.

Pros: Keep audible factory warnings.

Cons: Little loud, but you can make it lower by cutting a copper track on circuit board.

Crutchfield Customer Review (What's this?)

This was so simple I was completely surprised. It retained all the GM warning chimes as advertised while adapting the factory harness to the universal care audio color codes.

Pros: As stated plug-n-play.

Cons: The noted audio alert volume reducing solder joint on the PCB, could easily have been pigtailed to the outside harness of the box with a simple disconnect joint for users to test the audio warning sound levels.

VA Steve 55 from Leesburg, VA on 7/22/2014

2004 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

I used this adapter on my 2004 Silverado 1500 to install a JVC deck. This adapter does work and simplifies the wiring, but it has shortcomings. First and foremost, I found out when complete that it will not integrate with the dash light dimmer switch. Crutchfield listing has since been updated. So radio is always BRIGHT. Second, the chime box is poorly made and falls apart easily. Why couldn't they use 4 screws to assemble it? Had to tape it together. I'll live with it since the radio works, but if I had to do it over I would use a different brand.

Pros: Accurate wire diagram instructions and clearly marked wires, radio worked on first try.

Cons: Chime unit box cheaply made and must be repaired to keep it together. Does not work with factory dash light dimmer.

works good, easy to install, too loud even after cutting circuit path per instructions to switch from loud to less loud

Pros: works well.

Cons: if you didn't cut circuit, at least in my truck, you wouldn't be able to stay in the truck when door chimes are going off, way too loud.

2004 Pontiac Grand Am
Crutchfield Customer Review (What's this?)

Works great, the volume can be easily reduced significantly by cutting a single circuit path marked (highly recommend as its too loud unless you muffle it against the vehicles carpet) flimsy shell, easy to fit or mount, decent length of wire

Pros: Good length of wire, easy to wire up

Cons: Flimsy shell that houses circuit should be zip tied through it's own screw slots across as it can fall open while you are trying to mount

Works, sort of...

wenjen4 from Allen, Ok. on 5/2/2014

Crutchfield Customer Review (What's this?)

Build quality seems fine, and the volume was just fine. Wires were long enough to give me several mounting options. I did have a problem getting power to my head unit. The tech advisor helped me determine that there was a pin out of place on the factory harness. He helped me jump the wire and it worked! Can't say enough for the tech advisors patience and knowledge. Lefty was particularly helpful, although I talked to several other advisors and they were all wonderful.

Pros: Tech advisors were AWESOME!

Cons: Don't know if the pin was out of place on the adapter, or on my factory harness. But I'm inclined to think it was my truck. It is one of those Ok/Tx special packages with goofy RPO codes.

AndrewD from NorCal on 3/3/2014

2005 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

The unit seems to work fine. The plastic housing comes apart too easily and doesn't completely mate together, so I put a zip tie around it and through the mounting holes. Sometimes the chime keeps going after I remove my key, so I have to reinsert and remove my key again to make it stop. That only seems to happen if I turn off my ignition and remove my key quickly. The wiring harness was great for an easy install. I soldered all my connections to my new radio's harness and used shrink tubing to make it insulated and nice. My only complaint is that the illumination wire didn't do anything in my 2005 Silverado. Turns out the GM factory harness doesn't have a wire going to the illumination dimmer port on the connector, so I ended up T-splicing that wire into the brown/white wire running to the HVAC controls and it works fine now. If you're unsure of which wire to split, use a multitester. The voltage on the dimmer wire should vary as you adjust the dimmer control. This only works when the headlights are on, so you may need to cover the day/night sensor on your dash to get the lights on in the daytime. To the people complaining it is too loud - there are instructions on how to decrease the volume in the pamphlet that came with the device. It involves cutting a circuit on the board.

Pros: Wiring harness makes install easy Retain warning chimes

Cons: Illumination/dimmer wire does not work on 2005 chevy Silverado - have to splice into HVAC dimmer wire Plastic housing falls apart easily. Had to zip tie mine closed.

This adapter "confused" the BCM in my 2005 Colorado. After following all the instructions - exactly - step by step- and reconnecting me truck battery my POWER DOOR LOCKS and my DRIVER'S WINDOW would not work! After calling tech support I found out that this is not an uncommon problem. On line forums are also full of other frustrated consumers with the identical problem! Why wasn't this issue even hinted at in the product description? I stopped to talk a local car audio store. They checked in their data base and found the there was a warning about this very issue. Finally - after two weeks and numerous fix attempts suggested by Crutchfield and the on line forums the problem resolved itself. I say "itself" because one morning everything was working again after not working the night before. Ask a lot of questions before you buy this adapter for your car/truck.

This was a recommended part to retain the safety chimes that were removed along with the factory stereo. I was worried that it may not be loud enough once it was buried behind the dash, but my worries were unfounded... This puppy is a snap to install and the loudness was perfect, and I got a discount buy buying it as part of the audio package!!! Gotta love that.

Doesn't support illumination on a 2004 Chevrolet.

Anonymous from Champaign, IL. on 8/25/2013

2004 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

Don't let Crutchfield tell you that this is completely compatible on a 2004 Chevrolet Silverado, because the illumination feed doesn't work, and it won't dim the display on the aftermarket radio when the headlight or parking lights are turned on. Now I get to wait for a different product to be sent to me from a different manufacturer... and get to tear apart and re-wire the whole harness a second time.... along with the time involved for me to remove and re-install the head unit a second time. Plus, for me to get my money back for this first harness, I'll have to box it up, label it , and take it to a UPS location to send it back. Lucky me. Come on Crutchfield, get it right. Who is going to take responsibility for all of my wasted time and effort? No one. I bought from you because I assumed that you had all of this figured out. Apparently not.

Pros: Wiring is color for color.

Cons: Doesn't support illumination for 2004 Chevrolet.

Crutchfield response on 8/27/2013 Thanks for your review. We are correcting our presentation to show that this harness does not provide dimming for the car in question and other similar GM cars.

Installed in 2006 Isuzu I-350 with some soldering, and Heat Shrink Tubes. Zip tied beneath steering wheel under dash. Directions were simple to follow, and soldered ground to ground not connected to chassis as directed. Everything plugged in easily. The chime is way louder then factory chime. I bought it 1\2 off with Deck, still an added expense I was not expecting. Thank you GM for making as simple as installing an aftermarket radio more time consuming and expense.

Pros: Easy Install and directions.

Cons: Added Expense to GM Vehicles.

BK from Nebr. on 8/10/2013

Crutchfield Customer Review (What's this?)

NOT sure why I needed this....only bought it to keep Crutchfield support. I talked to many stereo shops and none of them could tell me exactly what I would lose if I didnt have it. I heard I'd lose warning chimes (no big deal to me) to losing stuff off the dash. Price was 50% off with stereo. I wish I looked at reviews before I installed it cause it is LOUD!!! I would have put tape over it to quite the thing down or cut a wire to lower volume.

Pros: works as it should, easy to install, worked well with new stereo harness

Cons: ITS LOUD, bigger than I thought it would be, cheaply made, a bit pricey but was 50% off with stereo

Works great! Retains needed chimes. It's a little loud but open it up and snip where it says "cut for lower volume" or something like that. It's still louder than the factory but who cares, it does the job. You better know how to solder.....

Pros: It works as it should so far!

Cons: You better know how to solder.....and follow directions.

Seems to work pretty well. Installation was a breeze. The new warning dings are a little loud and piercing. After a few hundered miles my radio says there is a miswiring and I haven't gotten around to looking at it yet.

Pros: Easy to use

Cons: Warning dings are loud and piercing

Much easier than I thought to install. Wiring diagram is good. Just remember not all wires will be used for all applications. Had to plug in chimes before able to listen to radio. Lesson learned.

Pros: Easy to install. Good instructions. Especially if you do not like the loud chimes, instructions tell you how to lower the volume of the chimes. A plus, since chimes are loud.

Cons:

Metra VT-GMRC-01 Factory Integration Adapter

Gregory H from Crimora, Va on 6/28/2013

I got this unit to replace a defective crux unit when I was installing a new Sony DVD in my 05 Chevrolet Colorado. Wiring it to the Sony harness was easy being its color coding matched the Sony's. The box is made to come apart so you can lower the chime volume by cutting on the circuit board. I did not do that. The problem is that the box will not stay together. I wrapped black tape around mine to hold it together and muffle the chime a little. Its very loud. Only Problem I see is that my radios dimmer don't work.

Pros: Works fine.

Cons: Chimes are very loud. Box is Cheesy, Radios dimmer don't work.

I used this product to install an AVH-P3400BH into my wife's Trailblazer. It was my first car audio install, and this product worked flawlesly. The great directions and color coordination with the reciever wiring was spot-on. The door ding sound is a little different tone from the factory one, but is not an issue. Sounds fine. This product is a must-have for the do-it-yourself installer. Couldn't be happier.

Pros: Ease of use. Works perfectly

Purchased this to install a Pioneer FH-X700BT in a 2003 Silverado. Connecting the wiring was pretty simple. There was nowhere to mount the auxiliary speaker, so I ended up zip-tying it to a bracket inside the dash. My only gripe is that the volume is obnoxiously loud.

Pros: Easily connected.

Cons: Obnoxiously loud, nowhere to mount speaker.

Glad they put in a way to attenuate the volume, I used that option. It does not chime in exaclty the same way as the car originally did, but I am still glad I got it. It works fine, it is nice to have those functions.

Pros: There was a way to attenuate the volume. It is good to have those functions.

Cons: There wasn't really a good place under or behind my dash to put the thing. I wound up taping it to the backside of the front of the center console. It is out of sight there, but I suppose after some time, the electrical tape will get tired, and I will have to tape it back up or come up with another way to hold it up. Almost forgot; the box snaps together, and it would sometimes come apart.

Essential piece of equipment--no way around it. Had to cut solder wire to reduce volume because it was REALLY loud; instructions were very clear on how to make this modification--took 30 seconds and was easy. Bought with steering wheel control wiring harness which made entire install easy; all soldering and wire connections were outside of dashboard (on the work bench) and you just plug it into vehicle and head unit.

Pros: Essential for safety

Thank you for suggesting that I was going to need it, I did. Well worth it.

Pros: Cables are long enough. Loud speaker, they show you how to reduce loudness in documentation included. I wasn't aware that GM had the warning chimes coming from the OEM head unit Avoid having to splice OEM wires. Attached it with a couple of zipties next to steering wheel, under instrument panel (still loud =) )

This item is necessary if you wish to connect an aftermarket stereo to your 2002 Chevy Cavalier, which I did. It maintains your door chime, key in the ignition warning chime, seat-belt warning chime, etc.. It wasn't terribly difficult to connect with a crimper and some butt connectors. The sound of this thing is far too loud for the confines of a vehicle. I ended up covering the unit with a couple layers of electrical tape to dampen the piercing sound. It worked, but it would be a lot simpler if the device came with a volume switch.

Pros: It keeps your car's warning chimes working while connecting your aftermarket stereo to the factory harness.

Cons: The separate chime is far too loud for my tastes and has no volume control.

Installed In Chevrolet Cavalier. Easy to install and good direction for connection to head unit . Fit to vehicle was perfect (wiring harness). Build quality of the little black box is questionable. Fell apart immediately out of the box. Had to wrap it in some electrical tape to keep box together. Chime is on the loud side and there is not volume adjustment for it. Wiring is long enough to mount box in different location from Head Unit so it will not impede head unit install.

Pros: Wiring harness was perfect. Wire color coding exactly matched my JVC head unit. long wire for black box.

I called Crutchfield about the need for this as I understood it was to provide you with all of the factory warning sounds. I told them I really didn't care about the sounds but since they stressed the importance, I figured for the price I'd go for it. What Crutchfield didn't tell me was this adapter has the prewired GM plug which made spicing wires to the new head unit a breeze. I did all of my soldering from the new unit to this adapter on my workbench, and then just plugged the plug into the recepticle the old unit came out of and the installation was done. No dripping solder in the vehicle and no scarred hands.

Pros: Easy installation

Cons:

I will need to charge my phone at some point so I'm glad I have them both, but I love NOT having my phone plugged in and controlling everything from the phone if I want to.

Pros: Dual USB ports. Variable colors are sweet! Bluetooth streaming is AWESOME! (It takes a USB port, but the adapter is very small and inconspicuous). Streams Pandora just fine, youtube audio, etc. Haven't had a real problem yet.

Cons: Mine isn't auto-adjusting the brightness for day/night... Not sure if it's because of the GM chime adapter or not. Sometimes it takes a little bit for the bluetooth to pickup my phone and start playing. It would be cool if that were quicker.

Crutchfield Customer Review (What's this?)

This is a required addition to any OEM replacement headend for GM vehicles. It allows the vehicles chimes (open door, seatbelt, etc) to be heard after removing the OEM stereo. Overall quality meets needs, but did cause me some concern. The plastic box does not hold together well, so I used 2 zip ties to ensure the top and bottom stay together on rough trips. It does not come with an easy way to connect to the new headend wiring, and does require a rudimentary ability to solder connections. Wires are well labelled and accurate. Customer support know the product well and was able to explain why I would use once wire over another for lights and dimming.

Pros: Well labelled wiring. Excellent customer support knowledge.

Cons: Plastic box is not well made, but easy to work around. Requires soldering of connections to radio wires for use.

Adapter for 02 Chevy Cavalier

Crutchfield Customer Review (What's this?)

after the success I had with my Hyundai Elantra dash kit, My sister-in-law wanted to see if we could have the same success with her Chevy Cavalier dash. Crutchfield.com to the rescue! The dash kit was extremely easy to install and thanks to 10 min. of prep work getting this harness ready, installing the after market head unit was a snap! you'll need the speaker since the stock stereo is used to pass through the door chimes whenever a door is ajar. we found a nice place for it behind the dash with enough sound suppression that we didn't seem to have the "too loud" problem every other reviewer seems to have had. If anything the little speaker was better sounding than the passthrough was!

Pros: easy to read schematics for wiring and 10 min. of prep work, and the harness was plug and play! another good quality product from crutchfield!

Cons: the wiring for the speaker isn't immediately clear. Once understood that it passes the power THROUGH and not TO, the rest was easy.

Pros: This interface makes install quick and easy.

Cons: None

Anonymous from Martinsville IN on 2/22/2012

Crutchfield Customer Review (What's this?)

Installation was not as easy as expected due the lack of easy connections between adapter and radio. Instructiopn sheet showed a link that could be cuto to lower volume but this wire was not available so only max volume was available. It would be great if Crutchfield could devise or locate small slipon connectors to allow a quick connection of the 20 plus wires needed to be spliced together. Supplying "flying leads" is not an easy install even for someone with my background in electronic repair and installation. Would be nice if "splce connectors" could be added to both the factory cable and the adapter cables. It is a no-brainer as connections are simply wire color matches.

Pros: Solved the factory "lock-out" features preventing direct replacement of non factory audio components

Cons: Flying leads requiring soldering is standard in industry but would hope that Crutchfield could find an easier solution

This unit does what it is supposed to by keeping factory warning chimes. After reading reviews, I made the cut for lower volume and it is now at an acceptable level. After a couple of weeks of getting used to it I can no longer tell the difference between this and the original chimes. Installation was simple. I was not thrilled to spend the extra money on this adapter but I guess you just have to bite the bullet.

It dings when it's supposed to and doesn't when it's not. I took the advice of all of the other reviewers and made the cut for lower volume, I can't imagine how loud it would be without it because it is plenty loud now. The color coding of the harness matched the Clarion receiver I ordered perfectly. My only wish is that the tone of the dings matched more closely the factory sound, but they aren't harsh by any means.

Had to purchase this to keep the chimes on my truck (not faulting the adapter for the purchase, faulting GMC for being stupid). After reading some reviews on it, I immediately cut the connection to turn the sound down (sound is right on par with the old factory sound lvl. Tucked the unit back in the front of my dash in a pocket. No rattles or problems yet and it has a decent tone. Wiring harness was easy to hook up.

Pros: Keeps the chime on the radio, adjustable chime volume, easy wiring harness hookup

Cons: Box is kinda big. If you don't cut the connection for the sound, it will be blasting

Duct tape over speaker for perfect volume.

StephenW from Del Rio, TX on 1/31/2012

2003 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

Only harness I could find to install an aftermarket radio in my 2003 Chevy Silverado. Chime works under all the circumstances as the factory chime. The chime is very loud, but was perfect volume after placing one strip of duct tape over the speaker. I used the mounting holes in the speaker bracket with zip ties to mount the unit to the back of a metal pillar directly behind the stereo head unit.

Pros: Easy to install, just match the colors to the stereo outputs, solder, and plug it into the truck harness. Chime works in factory conditions, maintains safety and keeps me from leaving my headlights on!

Cons: Initially too loud, one piece of duct tape over speaker fixed volume. Also, may not maintain factory dimming feature. There were two wires to my stereo head (ILLUM and DIM), I matched the wire colors from the harness which matched the ILLUM on my stereo. Perhaps if I wired the harness' ILLUM to the stereo's DIM the dimmer may have worked, but it is managable enough to not warrant taking everything apart again.

Pros: it hooks you up to factory plug ! no wires to cut !

Cons: wasn't a very well made part I'm not even using it now but i needed that plug to wire it up to my truck !

Get your soldering gun ready

Anonymous from Alexandria, VA on 11/10/2011

Crutchfield Customer Review (What's this?)

Installed in 2005 Colorado. The adapter can't possibly connect to every possible radio, but Crutchfield could make it easier by installing a universal connector with a brand-specific matching connector with whatever radio you purchase. Not a mechanical novice, so it wasn't difficult. Just a little time-consuming to sit at the bench and solder each wire to matching radio wires (Kenwood KDC-X695, see separate review). Only issue was orange wires. The adapter had orange (illumination) and orange/white (dimmer). There was only an orange/white (lights) coming off the radio. Some say if you wired the wrong wire it would fry the dash lights, I tried wiring both adapter wires to the radio and don't think this is true. Didn't give the radio dimmer capability so I unhooked the adapter orange simply connecting orange/white-to-orange/white. The radio lights operate but do not dim with the dash dimmer. Didn't even try the chime unit before cutting the high/low connector per instructions, and add a wrap of tape over the speaker. It's not harsh and works as factory. Aftermarket radios use standard color wires which simplifies installation. If you have any doubt, I would suggest you pay for professional installation. If you are handy with tools and think you can manage soldering two of the same color wires together 15 times, go for it. If you come across a situation as I did, coming up one wire short, the Crutchfield adviser should be able to help you out.

Pros: Nothing to love, it allows radio/light/power and chime operation as with factory that you would not otherwise have. Also wonder why GM routes all this through the radio?!

Cons: Having to solder each of 15 wires to the connector supplied with the radio.

It's unfortunate that the Chevrolet/GM vehicles need to have this whenever upgrading from the stock radio. I find the warning chimes absolutely necessary, though. It has chimed every single time the original would have. As others have noted and recommended, I snipped the connection to lower the volume, and it sounds just as loud as the original on my 2006 Chevrolet Colorado. The chime sound is slightly different from the original, but it's very similar. I got this product for half-price when I bought it with my radio.

A needed item, apparently, for the newer model trucks. What makes GM wire things through their radios is beyond me, but this module has to be in place for certain items to function. It does it's job, though the wires for the module itself to the harness could be longer - and a simple switch to change the pitch of the tone would be welcomed. As it is you have to disassemble the part and scratch off some of the solder to dim the chime... how dumb is that?

Had a tough time finding a good place to mount this on my '03' Silvarado crew cab, but once I found a spot it works as designed.

Other than that, I am glad I went with this even though I know I could have gotten away without it!

This adapter is well worth the money. It will keep the chime working so you don't leave your headlights on etc. The built in adapter saves time and provides a clean installation.

Initially I didn't want to shell out full price for this thing but then I found out that Crutchfield was knocking 50% off the original price with the purchase of a new car stereo receiver which is exactly what I was shopping for anyway. Man am I glad I decided to buy this. It doubles as a very nifty and very necessary wiring harness. It plugged directly into my factory harness then I just butt-connected the correct wires to my new stereo's harness and thanks to the easy-to-follow instructions included it was, well, very easy. Almost all of the other reviews I read say to cut the connection that makes it quieter. I highly reccomend this advice, it is plenty loud on the lower of the two settings. All in all it works great, made the stereo installation a little easier, and I am very pleased with this device.

It was great to keep the door chimes & warnings by the use of this product. It was easy to add during installation. The volume is much louder than the factory warnings, so I wish it had a volume control to bring it down a notch. The only real negative is that if the key is in & the door is open, it never stops sounding off. So when I try and have the radio playing w/ the door open when the vehicle is off, the chimes never stop. Even the factory chimes will stop after a few seconds. For safety reasons, it is great that this adapter keeps the warning alerts though.

GM Class II Data bus Interface - the right product for 2004 Chev Cava

KC from Surrey, BC Canada on 2/5/2011

Crutchfield Customer Review (What's this?)

This GM Class II Data bus Interface is definetly the right product for a 2004 Chevrolet Cavalier! It works great. It does what it supposed to do - that is give the 'chimes ' when you open the door, leave your keys in the ignition, etc.... Note: You will probably find it TOO loud (the beeping) so follow the instructions that comes with it to 'cut' the solder on it's circuit board where the arrow points too. This makes it about 1/2 as loud. Also, mounting it down on the ground up underneath the heat vent on the floor like i did (couldn't fit it anywhere else, behind the radio not much room, pretty tight) also makes it quieter. This device just plugs into your "GM factory deck wiring harness" it's simple: - pre-solder the wires from your new (aftermarket deck to this devices wires- color coded) - unplug your factory deck, plug this integration adaptor into the harness that normally plugs into the factory deck. - get the radio antenna adaptor - another product i bought, it just plugs into your factory wiring and has a adaptor on the other end to plug into your new aftermarket deck - you will also need a trim kit for mounting you new stereo into, if it is not DoubleDIN size. Normal decks are single , half the height, (aftermarket) whereas the one in the 2004 cavalier is double DIN size. Crutchfield sells this adaptor also. Good luck, and the sound on the aftermarket is wayyyy better than the GM factory deck in the Cavalier anyway!

Ok, you have to use this when installing into the relevant GM vehicle to keep things working. The box itself is HUGE for what it does. And it sort of rattles a bit if you shake it near the connector. Tape it up before you install it. In a truck, there are plenty of spots to hide it behind the dash, not sure about smaller cars. The instructions are not exactly correct. It tells you to install some wires that are ALREADY wired to the 24 pin GM connector. Just read it a few times first, then it all makes sense! There are TWO wires that control illumination (orange and orange/white). One is for "illumination" and the other is "dimmer". My pioneer only had one wire, which was orange/white. I searched the web and other said connect the orange on this device to the orange/white of the radio. Well, the radio lights up. ALL THE TIME. Does not dim at night. Make sure you test it first. I soldered it all up, and was not about to remove it to change the wire. I'll just live with it for now. Maybe on a warm summer day I will try the other wire!

Wiring is easy,and it is plug and play once you get the radio harness hooked up to it. The case is a little loose and can rattle, but i fixed it with some zip-ties.

Crutchfield Customer Review (What's this?)

Easy to install, but had to cut the specified trace on the PCB to lower the sound output. It is very loud if you do not do this. It also vibrates in the housing slightly, but it isnt too big of an annoyance since you only hear it everytime you turn on your car, etc.

Works like a charm. Very easy to install in less than an hour. Everything works as instructed. Just had to match the colors. Kramer, my sales person, was extremely helpful and paitient with me b/c I have never installed a radio before. He made sure I had everything I needed and explained it all to me. Will definitely buy from Crutchfield again.

Crutchfield Customer Review (What's this?)

This would have worked just fine except one of the electrical connections inside the harness (the yellow wire) was not solid. That is, the wire was not electrically continuous from one end, through a harness connection, to the other end. It took me some time with a multimeter to find which wire was bad and to make a splice to fix it. Other than that the harness worked fine but that problem is enough for me to give it a bad rating.

Amateur Radio RFI warning

Kyle from Norman, OK on 9/2/2010

I like this unit because I wanted to keep the Retained Accessory Power (RAP) otherwise I would've wired without it. It is very loud, I put masking tape on mine to make it quieter and less "tinny." If you have any kind of 2 way radio equipment in your vehicle, watch out, because this thing produces all kinds of RF noise around 2m (140-150MHz). I installed a separate 12V switch to cut power to this thing to cut out the RFI. The receiver has it's own 12V supply from the battery, so you can cut power to this thing without losing memories in the receiver. You can't use the car stereo while the switch is off, but I either use the 2m rig or the stereo. So when I want to use my ham radio, I just flip the switch off, then flip it back on when I'm done to restore chimes and car stereo functionality. Good Luck, Kyle

GM Intergration Adaptor / 2004 Chev Impala

Chris near Seattle from Seattle, WA on 7/31/2010

The 2004 Chev Impala . I was concerned as the factory radio controls the settings for several options as well as the Chime Warning controls. What I found was that the functions were retained with the Integration Adaptor at the preset setting I had used on the factory radio. I cannot change the preset for a function now unless I reinstall the factory radio. As examples the Headlight Delay functions still works for 30 seconds as I had it preset on the factory radio that way; The dome light still comes on when I pull the key out; the FOB/Remote Chirp stills works on the small chirp setting; when Remote unlocking at night the headlights come on; the radio stills plays for approx 10 minutes after turning the key off and stops playing when opening the door, the windows still power up and down during this 10 minute shut off period. The Dash Message Box still functions, Door Ajar, Trunk Open, Battery, Security still pop up. I had no way of checking the Low Oil in the Message Box. The Tire Monitor and Oil Change Service Soon can be reset manually via the headlight switch and gas pedal (refer to owners manually for procedure). The Chimes all work, including when I leave the turn signal on over 30 seconds. I did not have the wire cut in the Chime Box for a lower sound, instead the installer used tape over the speaker to adjust the sound level and velcoed it to the back of the center console shifter and it works great.

I bought the GM Factory Integration Adapter because it is important for me to keep all the factory chimes and safety features. It is easy to install. After reading other reviews, I cut the circuit board as suggested. I never tried the volume before I cut it. I used others advice for that. I am glad I cut it first, it saved a lot of hassle. The adapter works and sound great. It allowes me to keep all the features of my 2006 Chevrolet Colorado that I love. Great product!

2003 Chevrolet Silverado 2500/3500
Crutchfield Customer Review (What's this?)

This adapter was easy to install. It required splicing about (8) 18 gauge wires. There are two volume levels. The preset sound level is quite a bit louder than the factory GM warning chime. To set it to the lower volume you are required to cut a solder connection before installing the speaker. I attached the unit on my 2003 Chevy Silverado by Velcroing it to the inside of the dash just below the Pioneer stereo I installed.

Aaron from Abq, NM on 3/21/2010

Crutchfield Customer Review (What's this?)

I put this on a church van. I know you don't "have to" but I thought I should. A lot of people use this vehicle and I figured it would save a lot of trouble. I know I appreciate an audible warning if I leave the lights on or the keys in the ignition, so I figured other people driving a different (not their usual) vehicle would like it too. It may save a dead battery or stolen vehicle. I also like the fact that you can adjust the volume on the unit. HINT: Hook up the unit and loosely reassemble the dash so you can hear what it sounds like. When I first hooked it up I thought it was going to be WAY too loud. But, when I tested it, I found that is was a little softer than the factory setting. I'm not sure I would have been able to hear the device on the lowest setting... What would have been the point of getting it then? I only gave it 4 stars b/c of the instructions.

Matt from Nashville, TN on 3/15/2010

2001 Chevrolet Impala

My title pretty much sums it up. One of the major factors that made my decision to buy my Alpine IDA-X305 was the savings on this (necessary) unit. However, the sounds (or chimes) coming from this thing are down right obnoxious. Guests in my car are like, "what the blankety-blank is that?!" Not to mention if I'm on a phone call when it chimes. It's LOUD! At least the factory unit sounds were pleasant and-I seem to recall, but could be wrong-may have had a volume adustment. Part of my issue is I don't have the time or the know-how to dig in and mess w/ this thing. I paid a third-party/big-box to install it. I really don't want to have to pay them simply to muffle a chime speaker. Again, my gripe is with the unit. The retailers can't touch Crutchfield's pricing.

This was actually less annoying than the factory chime after modified per instructions and speaker opening was taped over. My only problem was the wiring diagram. The diagram for the speaker wiring was wrong or misprinted: just match the wire colors. Also, the diagram for the ground wire was confusing, but Cruthfield tech support was a big help. Overall, installation is much easier than trying to splice wires in the dash.

This product is great! It made for a super easy install of my new Sony Mp3 player in my 2000 Pontiac Sunfire. It takes only 10 minutes or less to attach this product to your cd players wiring harness. After that, it truly makes for a simple plug and play installation. The radio stays on until the door is opened just like the factory cd player. One complaint with this device is wow, the integrated door chime is LOUD(like annoying loud). Also the unit is not very ascetically pleasing, so you will want to tuck it somewhere where it can be heard but not seen! Thanks to the Crutchfield Team for another super easy installation!

Don't install a radio in a GM without it. I soldered all the connections at my work bench prior to installing on the truck. Wiring harness snapped right into the GM wire harness. With the adapter/harness, there's no need to cut into any of the OEM wires behind the radio. Not only did I not want to cut any of those wires, but they would have been hard to get at. NOTE: Like others have mentioned, this alarm box is LOUD. I used a utility knife and cut the circuit board where marked. I completely covered the grille on the alarm box. Now you can tollerate it. I didn't like paying this much for it, and I didn't like having to cut the circuit board. But, thanks for Crutchfield for marking it down to half price.

The device does what it is supposed to do. I'm more upset at GM that I even need this than I am about the quality and price of the device. However, the outer case on the device is not well made and simply fell apart when I unpackaged it. I had wrap tape around it to hold it together but since its out of sight it really doesn't matter. I followed the advice of other reviewers and reduced the volume of the device by following the manufacturer instructions for doing so. This involves cutting a path on the circuit board which is a pretty risky / unbelievable thing to find in an installation manual if you ask me but it worked. The wiring of the device was not difficult although I've had quite a bit of experience installing radios.

I have a 03 Oldsmobile Silhouette. When selecting my vehicle to find out which radio fits, I was informed over and over that I MUST have this part! Or else my warning sounds wouldn't work for open doors, keys in the ignition, etc. possibly causing injury or death. So I ordered the part. I proceeded to remove my factory radio, unplugged everything, turned my ignition on just to see if my warning sounds worked.. guess what... they did. I totally installed my new JVC radio, without this part. And everything works perfectly. Do yourself a favor, and pull out the radio you plan on replacing FIRST and see if your indicator sounds work, before you have the part sent to you.

The wiring sheet is pretty straight forward. If you've hooked up a sound system before you should be fine. I read the speaker was loud to begin with so I used some athletic tape I had laying around.

I am pretty annoyed that GM has made their wiring in such a way that you have to have this adaptor to install an after market stereo. It seems a little arrogant that they don't think that their parts will ever wear out. That being said, though, this adaptor worked beautifully. It plugged right in and was small enough to fit in a corner out of the way. A volume control would be a great improvement. This little bugger is quite loud! However, understanding how the system works, it is really best not to leave this bit out of your install. It does everything from warn you about your seatbelt, warn you that a door isn't shut to warning you that you have an engine problem. Don't skip this part!

Installed this in a 2001 Cavalier, along with a JVC KD-HDR30 stereo and four Pioneer speakers. This unit worked as described, and the instructions allowed me to connect the several bare wire connectors easily. I give it four stars only because it's WAY too loud, and having to cut through a connection on a circuit board is a pretty ridiculous way to have to drop the volume. That said, the instructions made it very easy to do, but still... It was great that Crutchfield cuts the price when purchased with a new head unit, but I'd have been more than willing to spend $5 to $10 more to have an actual volume control on this unit, instead of cutting a circuit and wrapping the unit in duct tape. Mounted the unit in an easily-accesible spot on the right side of the center console, under the dash, in case I have to apply more/less tape to adjust the volume. As always, Crutchfield's service and support were outstanding! The installation went without a hitch, and my daughter loves her new stereo!

Mike from Huntsville AL on 1/20/2009

Crutchfield Customer Review (What's this?)

Installed this in a 2003 Chevy Express Van with the Pioneer 8000BT head unit. I almost didn't order this component because I don't care about either OnStar (equipped but not used) or the "door chimes". But I decided to install it because the Crutchfield guy said to sell the vehicle in some states, they require the door chimes to work as part of the state inspection. Then afterwards, I figured out (I think) that it is also the low gas warning and the "you left your brakes on" warning and "you left your lights on" warning, and those are very important to me, so I'm glad I purchased this. They should refer to those chimes as the "factory warning chimes" rather than the "door chimes". Same complaint as everyone else - too loud. I cut the circuit board trace (we really shouldn't have to do that), Then wrapped it in a rag and taped it up with duct tape. Now the volume is about right. Also had trouble with cover staying on. The duct tape resolved that, too. For Illumination, I spliced orange/white to Orange, as the Crutchfield advisor said, rather than to the more logical Orange/White, but my display doesn't dim with the headlights, either. In my case, I suspect the Head Unit because other customers complain about the same thing. Why is it so hard to get a normal thing like dimming to work? Overall... a necessary thing that works well enough after some jury-rigging, but the manufacturer should be doing better than this.

Scott from Mpls, MN on 1/6/2009

Get this unit because it makes the wiring process 100 times easier. One for one wiring can be done away from the car, then plug and play. I have a 2004 Tahoe and the only item to watch for on the wiring was the orange/white wire. I believe I wired O/W to O/W and the unit display doesn't dim with the lights, so I think it should have gone to the Orange only. Not a big deal, because the display is not too bright at night. Chime is way loud. I should have used the directions to cut volume, but instead covered it up way under my dash. Still too loud. Overall, it's well worth the money if you're not an expert installer.

I bought a new Kenwood receiver for my 2004 Cavalier and decided not to get this recommended adapter at first because my door chimes don't work, and I didn't want to spend another $$...but as it turns out, even though my chimes don't work, I still needed this adapter b/c the wiring harness I got with my stereo doesn't fit into it's counterpart in my car-it's too small. So, the adapter is like the middle guy here, and definitely a necessity.

it does what it says, but it is LOUD, and the speaker and housing is cheap. For the price, I would think that Metra would be able to integrate the sound through the speakers of the vehicle.

I didn't think of taping over the speaker, but I am doing that tonight.

BrianK from Hendersonville, NC on 8/11/2008

This device gave me back two important things: The ability to listen to the radio with the ignition key in the off or accessory position and the chimes. Note: While the radio remains on when the ignition key is set to "off", it will turn off when the drivers door is opened. It was a bit pricey, but hopefully worth it. Interestingly, the first day, it did not keep the power on when I switched the key from "run" to "off", but the second day it does. Does anyone know why it would change? I mounted it in my Silverado behind the panel under the steering column. That way I can get to it easily if I want to go back and put some tape over the speaker. Definately cut the trace for lower volume. Brian

MAY03LT from Charlottesille, VA on 3/17/2007

This unit gave my 03 Trailblazer its chime back, as well as the ability to listen to my radio with the key off. The cables for the unit were long enough, and the unit was compact enough to hide out of the way easily. Im with the other reviews here, be sure to mute the volume before you install it (very easy fix).<BR><BR>At first I went the cheap route with a generic harness. However I lost the chime, and whenever I wanted to listen to the radio, the key had to be on, so the cluster and hvac control backlighting were always on unless I turned the dimmer off. Also, now if I leave the keys in the ignition, run low on fuel, or dont have a door closed I'll know it.<BR><BR>If you have a GM that requires this module, I highly recommend it over the generic harness. Even though the price is 4 times higher it is well worth it.<BR>

This made my installation so simple I think my 8 year could have done it. Is it worth $80.00? I dont think so. Thankfully, I got it for half price with my HU from Crutchfield. Was it worth $40.00? Definately! <BR><BR>For some reason the lid to the unit would not stay on so I had to electrical tape it on. Since its out of of sight, that really didnt bother me at all. After splicing the wires from the unit to my Hu wiring it looked like a nitemare. Some wires are way too long. I think some more thought could have gone into this. After alot of cutting, splicing and wire ties, its was all good. As Everyone says: Its too loud! Oh yes it is. I didnt feel like crawling back under the dash,disconnecting and slicing the circuit board to quiet er down. So I just put a piece of 2 inch masking tape over the speaker opening. That got the job done. <BR><BR><BR><BR>

Works perfect in my 04 silverado. Like everyone else said it is very loud right off but just look at the instructions and it shows how to quiet it down still a little louder than stock but works very well. Price was a little expensive right off, but if you buy a head unit you get it for 40 so its not bad for the money.

John from Metter, GA on 8/17/2006

Crutchfield Customer Review (What's this?)

Device works as advertised. It's just too expensive for what it does. That's a little much for a glorified door chime. Other than that, no problems, wasn't any different than other stereo installations I've done. Crutchfield as usual has the best instructions, kits, etc. in the business. They do need to re-evaluate the price on this one though......

Crutchfield Customer Review (What's this?)

I am writing this review for a previous buyer who indicated they had issues with this product. The issue was chiming uncontrollably and losing the constant power . Since I was experiencing the same thing and other reviews indicated no problems, I had to look into this. First I double checked the wiring (which was done by an installer) no problems there. It was wired correctly yet it would chime w/o stopping and my radio would not remain on while door was closed. <BR><BR>Resolution: DEFECTIVE UNIT. How do I know this, well I decided to purchase a different interface and it works perfectly. So if anyone gets this one and has uncontrolled chiming and radio does not stay on, its not the wiring its the unit, just exchange it

product works as it says it should. as many have said it is very lound unless u cut the circuit (very simple). but i only gave this a 3 star as its way to much money for what it does i think i could honestly live with out buying it. all it does is tell me if i left my lights on and plays cd player after car turned off untill door is open. for 80 dollars i dont think its worth it. oh and whoopy doo the door is open ding ding ding. .. i do have to say tho it does work.

This item works perfectly in my 2005 Chevy Impala. The initial volume setting is WAY too loud, but after reducing the volume (read the instructions!) it's perfect. All sound chimes work as they did before (including "low gas" and etc.) and the sound keeps playing after key is removed and until door is opened.<BR><BR>The only negative is the price, but Crutchfield eased the pain by offering this part at half price with the purchase of a headunit.

Ian from CT on 3/31/2006

This will be a repeat of what the majority of people stated already, it does exactly what it says, I mean exactly! No problems with the wires or the installation. The instructions may need to be updated however because wires that it tells you to hook to the harness are already hooked up (not really a problem but it's a review right?), besides that on problems what-so-ever.

Theo from Corpus Christi, Tx on 3/12/2006

This is a pretty cool product. It works just as advertised. I installed the Pioneer AVH6500DVD in dash player in my 2005 GMC Envoy and it is flawless operation. I have two complaints though, the first is the interface unit is way to loud for the door chimes but if you follow the instructions that come with it then you can fix that. The other thing is (I CANT BELIEVE there is no interface that works with the ONSTAR SYSTEM). It's still a good product but as soon as something comes out that utilizes the onstar system then I'm going to rip this one out and put that one in.

Well readers if it does not work check your craftsmanship....i am very impressed after adding the adapter with my Alpine head unit it has brought my stock speakers to life. It still keeps the door chime and all other audibles and on my Trailblazer when i pull the keys out the music plays till i open the door....YEAH BOY.....ok so i lost ON STAR that is the only negative. i guess i will cross my fingers and keep my cell phone charged........i hope this review helps.

Note: Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible and what additional accessories will be needed.

Retained Features: The GMRC-01 provides +12-volt accessory output, retains warning chimes, and retains R.A.P. (retained accessory power).

  • +12V Accessory Output: In many GM vehicles, there is no 12-volt accessory wire in the factory harness, which requires the installer to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. The GMRC-01 is designed to provide a 12-volt/10-amp switched accessory output (red wire).
  • Warning Chimes: The GMRC-01 retains factory warning chimes through the use of an on-board speaker.
  • Retained Accessory Power (R.A.P.):  The ignition power source of most GM vehicles keeps the radio on until one of the doors is opened. This feature is called the R.A.P. (retained accessory power). The GMRC-01 is designed to retain this feature.

10-Pin to 24-Pin Harness: The wiring harness has a white 10-pin female connector (4 pins present) on one end and a gray 24-pin male connector (14 pins present) on the other end. The 10-pin connector plugs into the GMRC-01 and the 24-pin connector interfaces with the existing factory plug. The harness also includes 14 bare wires that will need to be hardwired to your new aftermarket radio's harness.

5 questions already asked

I am not 100% if it will work but it should. You just have to connect to radio and then a power ground and signal wire if I recall, been a little while since I installed to remember exactly what it took. Best of luck to you, BTW great truck wish 8.1 was still made. [ AARON E  Jun 18, 2014 ]
Zeb I installed this kit with a Kenwood system in my 2006 Chevy Colorado Crew cab 3.5 l about a year ago and it works fine. I recommend cutting the trace for the chime to have a lower volume since it was rather loud before that. The only thing I noticed and I am not sure if this is because of this kit or the Kenwood but my key less entry is sometimes slow to allow me to lock the doors when exiting the car. This it is little concern to me since I prefer to use the lock button when exiting my vehicle. Like you I do not have Onstar or steering wheel controls. [ GARTH P  Jun 18, 2014 ]
It sounds like it is the right option for you. [ FRANK  Jun 18, 2014 ]
I don't think you will need this for your truck. It is meant to allow the door chime and warnings that come through the stereo if you have the on star system. Hope this helps. [ CHRIS  Jun 18, 2014 ]
It works in my 1500. This is the second one of the buzzers I've had. The first one died. I replaced it when I upgraded to my present receiver. New one has been fine over a year now. Be careful not to pull you a/c lines tight and double check that their plugs are tight and straight just before you close it up. GMC for 2004 has an issue with the a/c changing to heat randomly. They say it's these connections. It's really grease dripping on the control servo but there could be more then one problem. This has plaged General Motors on a few models for several years right in that time frame. [ TERRY  Jun 17, 2014 ]
It should work fine because it hooks up to the back of the head unit. In my 2003 chevy silverado 2500hd the key reminder beep was installed in the factory radio. [ RAYMOND O  Jun 17, 2014 ]
I'm not positive but I would guess no. My 2005 Silverado 1500 does have steering wheel controls. I would speak to a Crutchfield representative to make sure though. [ Rich  Jun 17, 2014 ]
Unfortunately we can't answer specifics about vehicles that are sold overseas (as the wiring can be quite different from country to country). This harness does make a connection for 12v ignition in the American version of the Chevy Colorado. [ Jeff  Feb 25, 2014 ]  Staff
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  Feb 05, 2014 ]  Staff
For details on fit or installation please contact an Advisor by phone or online chat. They will be able to pull up your vehicle and give you the details and what you will need for an installation in your vehicle. [ Jeff  Jan 06, 2014 ]  Staff
Originally I had just the installed 2 way speakers and now I have 1 fosgate p3 10" woofer with jl 300 mono and everything operates the same. [ AARON E  Dec 31, 2013 ]
I installed this on a 2004 Chevy Silverado. The wires on the harness solder into the wires from stereo,as well as about three wires from the door chime. Then just plug into your old wire plug from your car to your new harness you just soldered onto your stereo stereo. They are all color coded and makes it easy, I did not use an additional amp, but I think the amp plugs into the stereo by RCA cables, so it would not make a difference. One more word of advise, wrap the new door chime in bubble wrap before placing in dash to stop any rattling noise while driving. Lots of videos on youtube! Good luck! [ JOHN  Dec 27, 2013 ]
Since it's wired directly to your factory harness, it shouldn't be a problem. [ PHILL  Dec 27, 2013 ]
I do not know the answer to this question [ ROB  Dec 27, 2013 ]
I was installing on an unamplified system, but it did have the wire to integrate the remote amp power control from the aftermarket stereo to the factory harness. I assume it would probably work... [ FRANK  Dec 27, 2013 ]
