Metra VT-GMRC-01 Wiring Interface

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.

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.

Crutchfield Customer Review (What's this?)

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 August 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.

this product seems as though it works as it should.

Pros: allows the warning chimes to work

Cons: it is extremely loud,and annoying at the factory level - you definitely want to cut the connection for a lower volume for the chimes.

The interface hooked right up and kept my warning chimes and other features. The chime is a bit loud, so it is best to check it before the install. Sounds almost like the original chimes.

Pros: This interface makes install quick and easy.

Cons: The cut out to quiet the "ding" did not work, but a piece of duct tape over the speaker got the job done..

Works as advertised. 10 minutes with a soldering iron and voila'. I cut the jumper to quiet the "ding" as well as a piece of duct tape over the speaker. Now it is audible, barely, which is perfect to me.

Pros: 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.

Crutchfield Customer Review (What's this?)

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

the product worked for my 2005 chevy express cargo van hooked right up and kept my warning chimes and other features just like factory. even though it costs a little more than i wanted to spend it has to be used to upgrade your stereo so just buy it and chalk it up to the over all cost of upgrading your sound.

Pros: keeps the factory features

Cons: added cost for my stereo installation

Well it works and does what it is suppose to. However it is giagantic, no idea why it needs to be so large.

Pros: Half off with stero purchase and does just what it is suppose to.

Cons: Very large and bulky. If mounted outside of your dash , the sound maybe too loud. However the sound can be lowered by following the directions and opening the unit.......or I would simply tape over. The directions are ok, but could be improved upon.

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.

bought this Adapter because i needed that to hook up the JVC head unit that i got from crutchfield a few years back .anyway it worked ok at first but i was on my way to work one morn stoped for a errand . got in the truck and it would'nt start .no dash lights nothing like my battery was dead .i unpluged the adapter .put the key back in and it fired right up . so i ended up cutting the red wire from the adapter hooking it up from the battery with an extra switch

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.

You don't need this part for safty

Dave from Detroit MI on 10/10/2011

Crutchfield Customer Review (What's this?)

I ordered this part on the extremely high recommendations by the Crutchfield sales staff. They stated it was required for safety. All this part does is ding when the you start the car (regardless of if your seat belt is on or door is closed) and when your gas light turns on. This adapter is almost completely worthless. Definitely not worth the price.

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. Had to cut the board where it is labled to quiet the thing down as out of the box the thing will wake the dead! Other than that, I am glad I went with this even though I know I could have gotten away without it! The wiring was a bit tricky and a few calls to the support line were made as there are "optional" wires you may or may not need to connect depending on the options in your vehicle. But, the tele-support folks are AWESOME and will get you straight!
