Our take on the Metra 99-7503 Factory Integration Adapter

by Ryan Steele

You bought a 2003-05 Mazda 6 — great car, but its console makes it impossible to upgrade the factory radio. Metra's integration adapter allows you to install an aftermarket DIN-sized (2" tall) stereo in the Mazda's dash panel, while maintaining all heating, ventilation, and air conditioning controls.

The adapter is a perfect match for the color, texture, and contours of your Mazda dash. Warranty: 1 year.

Features

Vehicle Compatibility: The Metra Turbo Kit 2 (99-7503) is designed specifically for 2003-2006 Mazda 6 vehicles. The 99-7503 allows you to replace your factory stereo with an aftermarket stereo to improve the overall sound quality of your car audio system. Please consult Crutchfield's Vehicle Selector to see if your vehicle is compatible.

Install Kit w/ Integrated HVAC Controls: The installation kit features a recessed opening that will fit most single-DIN aftermarket head units. The kit features high-grade ABS plastic and is contoured to match your vehicle's factory dashboard color (silver) and texture. The install kit also retains full functionality of your factory HVAC system by integrating soft-touch button controls into the front-panel of the kit and allowing the use of your vehicle's factory dash vents and rotary control knobs. All buttons are backlit for easy viewing and duplicate the factory lighting in your vehicle. In addition, the installation kit features a factory-styled hazard lights button.

Wiring Harness: The Metra Turbo Kit 2 (99-7503) also includes the wiring harness which connects to the install kit, your vehicle's factory radio harness, and your new aftermarket head unit. The 5-pin clear connector of the included harness and the vehicle's 16-pin factory radio harness plug into the back of the installation kit. The multi-pin red molex connector of the wiring harness will plug into your vehicle's other factory radio harness. The un-terminated wire leads of the included harness will need to be spliced or crimped onto your new aftermarket head unit's wiring harness (installation tools and accessories sold separately).

An easy installation

Written By Blaine612, Austin, MN on Saturday, October 05, 2013
Crutchfield Customer Review (What's this?)
 
This product went in smoothly. The old one was a bit of a challenge to get out because you have to remove the shift knob then the console then remove screws to take out the old part to put in the new part. But once that is done it is a breeze to put in the new adapter. And it was a great deal I got it half off when purchasing my CD player at the same time.
Pros:
Great color
Cons:
Can't customize the color to match the outside paint job

Does the job

Written By LawrenceR, Noble, OK on Thursday, August 22, 2013
Crutchfield Customer Review (What's this?)
 
Anyone with a Mazda 6 first gen knows how involved a stereo swap can be. This unit aims to simplify the process and leave you with a factory looking dash surrounding your new head unit. The unit does essentially that, but not without some install frustration and living with some less than fantastic "fit and finish" results. First issue I had was 2 LEDs on either side of the hole for the outer HVAC knob were broken off in the box. Second issue I had to deal with was poor instructions for wiring and install. One entire harness was not mentioned in the instructions as needing to be connected (though it was pretty obvious it belonged and fit directly), also connecting the remote lead for the factory amp was not mentioned and was not on the primary harness and was easily missed during the first round of install. Finally, the "fit and finish" is less than stellar, especially considering the units price tag. The unit does not fit flush into the dash on the upper corners and protrudes a bit, and the lighting around the climate controls is very orange instead of the factory red, and bright in the center as opposed to the even light distribution of the factory lighting. Overall the device does its job of allowing the install and maintaining climate control and a close to factory look, but at the price(or even after discount for pairing with a head unit), the unit should really have better fit and finish once installed.
Pros:
Fairly easy install, allows you to keep climate controls and maintains a fairly factory look
Cons:
Poor install instructions, poor fit and finish, lighting color does not match factory

Works Fine

Written By ninnylala1, Rome, NY on Monday, July 22, 2013
Crutchfield Customer Review (What's this?)
 
Cructhfield should change the picture they have up. They should so the part as it comes with no ac buttons showing. IT DOES NOT COME WITH THE BUTTONS. You take the AC/heater contrrols off old piece. You will need the rings that go around the buttons. You have to take the stock radio off to get those off. I called Cructhfield and they told me new ac buttons come with it and they sent me a new one. That was a waste. Everything else worked and fit fine Do not forget to take the screw out through the glove box or you will not get the old one out. Thier is one Youtube video out there that doesnt tell you about it.
Pros:
Looks good. Pretty easy install.
Cons:
Only option.
Crutchfield response on Wednesday, July 24, 2013
Thank you for your review. You are correct. With this kit, you use your existing climate controls and vents. We have updated our information.

Great fit in 2005 Mazda 6

Written By Kris, Georgia on Wednesday, June 12, 2013
 
I took this adapter to a local shop and had them install my new unit and it fits good. I wish I would have gotten the adapter so my steering controls would work but it's not that serious to me. I really needed to replace my factory radio b/c it would skip every cd (new and Old).
Pros:
Perfect color and good fit.
Cons:
Needs work to fit AC controls properly.

Metra 99-7503 Factory Integration Adapter

Written By Jason, Marrero, La on Saturday, May 25, 2013
Crutchfield Customer Review (What's this?)
 
Instructions detailed and straight forward. Color slightly different, but not bad. ISO install somewhat tight, but a must unless you want to modify the metal DIN mount to make trim plate fit. Also DIN install sets recessed into panel which I personally didn't like the look of. Overall pleased with product as both mounting options are included.
Pros:
Mazda 6 now has Kenwood!!! Everything needed is included Fit is nice and tight, no rattling or looseness
Cons:
Silver color not a perfect match, unless your Mazda 6 is a show car, definitely acceptable.

Crutchfield Customer Review (What's this?)
 
well I did a lot of research, reading reviews and the more I read the more back and forth I went about replacing this. I heard lots of cons that I have not found. my piece arrived, and I did not find the quality cheap, the buttons for ac and hazard light are great, even for my picky self, the install took 3 hours total, for removal, install headunit and steering wheel control module (which I recommend doing). I went with Crutchfield cause the package deal can not be beat, this included everything, brackets, wire harness, and step by step guide. I'm very pleased with this item.
Pros:
looks, function, close to stock quality, fit..
Cons:
one piece was loose and I had to super glue in wire harness. No big deal though.

Very Nice

Written By SH, Columbus, OH on Sunday, May 05, 2013
Crutchfield Customer Review (What's this?)
 
Very nice looking product. Works well. The only issue I had was that the factory HVAC buttons didn`t want to fit into the holes all the way. I realized that there was some residual material along the inside of the holes leftover from the molding process. A careful scraping along the inside of the holes and it was a perfect fit. The opening for the headunit is a little deep, but just use the tabs on the headunit frame to space it out a little if you need it.
Pros:
Good fit in the dash. Electronics on it works seamlessly.
Cons:
Had to trim the HVAC openings a little.

Could be better

Written By Jesus, Fallbrook, CA on Friday, April 05, 2013
Crutchfield Customer Review (What's this?)
 
Got this for my dad's vehicle so I could install and aftermarket stereo and add some amp to it. The buttons on the new dash do seem cheap and a bit out of place. However they do work and are not stuck as I have heard from other people. The finish on the panel matches the other trim pieces very well. I was worry it wasn't going to mach like the Infiniti G35 kits do so that was a welcome surprise. The locking tabs that lock into the dash to hold the stereo in place were not that secure. I had to put some folded electrical tape to push the tabs outwards to get a good lock on it.

Now to what I really didn't like. The instruction that came with the kit while at first seem detailed they skip something thing that would of made this install much quicker and less of a hassle. The openings were the AC control go have a lip that had to be sanded down. The opening on the back where the AC controls need to be placed doesn't no have the adequate room to fit them in, so some trimming is necessary. The led boards that to the AC control for illumination don't line up either so they had to be set a bit loose.
Pros:
Matches the trim nicely, harness comes well laid out, panel doesn't feel flimsy.
Cons:
Needs work to fit AC controls properly.

Metra Turbo 2 Mazda 6 Stereo Integration Adapter

Written By cwp, O'Fallon, IL on Tuesday, January 01, 2013
 
I was suspect on the quality of this car stereo adapter based upon previous reviews I'd read, but fortunately it turned out to be better quality than expected. However, several factors could make this item much better. First, the only thing that supports the stereo is two plastic tabs at the bottom of the slot where the stereo fits into the console. (I couldn't use the DIN cage that came with the stereo because it would have prevented the matching face plate that came with the adapter from snapping into place.) Also, the adapter face plate didn't snap into place very securely, so I had to use two 11-inch cable ties (routed under the face plate tabs, and around the whole stereo) to secure the radio into the adapter. In addition, the radio electrical connector that comes in the box didn't have enough pins in place to adequately wire the stereo to the vehicle harness. (The slots for the pins were actually there, but no pins in all the slots). I had to cannibalize a connector from the old radio, and use the pins from it, to make all the necessary electrical connections. Recommend Metra put a connector in the box with all the pins in place, and the installer can then just use those that are required for the particular radio they're installing. Finally, there was no way to secure the adapter back into place with the 10 mm bolt originally removed through the glove box. So, Metra should design the adapter with an arm to secure it back to the car with the 10mm bolt.
Pros:
Blends well with the original interior, and looks like the OEM console.
Cons:
Too many shortcomings (see review) considering the price of this adapter. However, with a few easily implemented improvement from Metra, it would be a great product.

Not sure why everyone hates this....

Written By Dino m, Lancaster, PA on Sunday, January 01, 2012
Crutchfield Customer Review (What's this?)
 
I ordered this part, in order to install a Pioneer headunit in my 2003 Mazda 6 s. Let me start by saying that this is the FIRST time that i have ever even touched car audio equipment. Considering that, i found the install for this to be pretty easy. When you install it, connect the headunit to the adapter, at your kitchen table or somewhere that you have room to work. Also make sure to use wire harnesses, they make the process of connecting wires VERY easy. If you have any problems, just call crutchfield tech support, they are very helpful. Also, if the trim plate does not fit well around your headunit, break off the plate's tabs and use double sided tape around its edges to secure it, the tape isn'tnoticeable and holds strong. If you use a bit of common sense, this install is a breeze!
Pros:
Simple install, same color as factory dash.
Cons:
Hazard button seems cheap. Paint scratches easily.

It's really not that bad

Written By Nelsen, Providence on Sunday, September 11, 2011
Crutchfield Customer Review (What's this?)
 
Pros:

- Color and paint finish are quite good. Looks great. - Fit is good enough... not perfect, but good enough - Everything worked perfectly (once I figured out all the wiring) - It's a solution. Your only solution if you want an aftermarket head unit. Worth doing despite the fact that it's not great.

Cons:

- Yes, the buttons are terrible. Lower three are ok, the hazard button is the real problem, which is much too stiff. I removed some material with a dremel tool to make it softer, now it is acceptable.

Overall, it's not that bad, and I'm ecstatic to have a good head unit now. It looks great, and the poor buttons (which you rarely use) are not that bad.

Not an easy install, however. Not recommended for an unexperienced installer. The head unit, climate control, upper display, and steering wheel controls are all intertwined... take your time and do it carefully.

Those who slam this thing: bare in mind how difficult it is to reverse engineer something like this. It's not like Mazda is providing them with engineering files to make life easy.

Bottom line: It's a solution. If you want an aftermarket head unit in your 6, this is more or less your only option. The negatives are not enough to not get it.

happy with adapter

Written By Rich, Media, Pa on Wednesday, August 17, 2011
Crutchfield Customer Review (What's this?)
 
After reading all the reviews on this product, I was worried about the adapter fitting correctly and causing new problems. We were happy with the product, the fit was good, and the other reviews gave us some good hints. (like covering the gear shift, almost impossible to not scratch the adapter if you didn't cover shifter). Instruction got a little confusing regarding if you have manual or electronic air cond. system. Overall, the adapter worked out great.

Fits but not easy to install

Written By Tim D, Nashville, TN on Tuesday, April 19, 2011
Crutchfield Customer Review (What's this?)
 
Installing this is by far the most complex stereo install I've done (I've done 4
or 5), so not for a novice or feint of heart. The unit works fine when
installed, however, including all AC controls and vents. Instructions are
included but are not the best, and I missed a step and didn't realize it until
after it was fully installed. Fit is good, but I have a head unit with a
swivel-down control panel, and it bumps into the bottom of the din
cutoout...which means the control panel is not able to open fully. Despite that
I'm still able to get CD's in and out.

For Mazda owners with manual HVAC controls: the fit for the controls is tight
but works, you have to nudge them into place, working around all the contours of
the HVAC control housing.

Leave yourself 2 hours or more for this install (for just the head unit).

It's overpriced, made with cheap material, and doesn't fit properly.

Written By Anonymous, Dallas on Saturday, December 04, 2010
Crutchfield Customer Review (What's this?)
 
For example, the 3 AC/Circulation/Defrost buttons in the middle feel like buttons you would
push on an MP3 player or cell phone. That itself isn't a big deal. But if you press even even
the slightest off the center of the button (for example, just a few milimeters off the edge of the
button), it gets stuck and will not reset unless you tap it or pry it back into place. Not good if
the defrost is stuck in the on position and cannot be turned off.

The hazzard button is even worse. You have to put about 10-15 lbs of force on it before it
even moves. When the lights begin to flash and you let up on the button, it gets stuck.

It feels like it was painted with model paint you would use on a plastic model car.
Once completely installed, the unit did not sit flush with the dash. It may be because the tabs
that hold it in place are too long.

It's sad that there are no other companies that make a replacement similar to Metra's.
Because not, Metra can price it as high as they want, and design it as low grade as possible.
Take this as a lesson in capitalism and competition. So in the end I reinstalled the old Bose
unit and attached an external USB device instead.

I would not recommend buying this. I got mine half price, and they would not accept a refund,
so I decided to just take it apart and look inside. I laughed and concluded that it must have
been intern-week at the company, just letting the students from a local junior high school
design it.

works ok

Written By exiledtiger, Milwaukee, WI on Sunday, July 19, 2009
 
Installed a week ago. The clock works! No lost time. Metra tech support says the issue was fixed and they are right - Mazda clock hasn't lost a minute.

Fit not perfect - sticking out a little at the top right, will work on that.

Buttons work - different feel. The big questionj here is long-term reliability. Will the buttons still work in a year? 10 Years? Whoever owns the car then will deal with it.

Holds the stereo well - I was concerned about the HU bouncing out or breaking the faceplate on bumps so I braced it inside the dash. Several road trips, several potholes, all ok.

Overall, I recommend it because its the only way to get the in-dash DIN.

(Also used the PAC-SW steeringwheel audio controls adapter - works great)

I should have listened

Written By Pigeon, Ocala, FL on Wednesday, April 22, 2009
Crutchfield Customer Review (What's this?)
 
I should have listened to the other reviews. I knew is wasn't great so I didn't expect much.

The quality is sub par at best the buttons DO NOT look exactly the same they are very cheap and barely work. I had to mess around with the buttons before I put it in because they won't push down. Like i said very cheap.

The worst part is the clock. I've had it in my car about 2 days and its lost about 20 minutes.

I wish I could use some other kit but this is it.

Its not all bad though it looks very similar to the factory panel and it did fit well.

I just wish they would fix the problems. I paid good money and expect more for what I paid. I think Metra could and should fix it if they want anyone else buying it.

Necessary piece of junk!

Written By steve, Warwick, NY on Tuesday, April 14, 2009
Crutchfield Customer Review (What's this?)
 
The reviews for this mounting panel are all pretty accurate. The fit isn't too great. The finish isn't that great either. The buttons are absolutely horrible, it would be hard to make them any cheaper than they are. My biggest issue is that my Mazda clock now loses 10 minutes a day. It's driving me crazy. The stock radio was pretty bad, and there is no other way to replace the radio without this. It was half price since I purchased a HU from Crutchfield. If I paid full price I would be really upset. You have your choice. Either swallow the not so great stock radio, or swallow this thing.

it's your only option

Written By Jim, Cincinnati, OH on Monday, February 23, 2009
Crutchfield Customer Review (What's this?)
 
If you are adding an aftermarket HU to your Mazda 6, this is really the only option you have... BUT, be warned before you start - this thing is plagued with troubles.

(1) Several people have complained that after installing this, the clock in the display area looses about 10 minutes PER DAY. Metra tech support was not helpful.

(2) The defrost control no longer work as stock. In the stock unit, when you turn on defrost, it automatically uses the compressor to help remove humidity from the air inside the car. It no longer functions this way. Also, the old unit would not let you change the recirc button when you were in defrost mode. This unit will allow you to do whatever you like with the buttons. Set them the wrong way while trying to defrost your windows, and they will fog up horribly.

(3) The paint is very thin, and scratches very easy.

(4) The fit is so-so. As someone else said, I find myself constantly pressing on it trying to get it seated right.

(5) The tactile feel of the buttons is absolutely HORRIBLE. They barely press at all, actually. It feels like you are pessing against a solid piece of plastic, rather than a button.

The ***only*** good thing about this is that I now have a navigation unit in my car. Other than that, this thing isn't worth 2 cents.

If I had it to do over again, I'd probably just leave the stock head unit in there, and trade the car in for one with a Nav unit.

I took my old one out in about an hour the night before I got my new one. Its not hard if you read every thing before hand. I gave it a three because the buttons are not worth the price every time i press the middle button the rear defrost comes on and the hazard light button is terrible. it nothing like the oem one and the paint is very thin if you don't want to mess up your new adaptor i would suggest that you cover your shifter with a towel or some kinda cloth but over all i have to say i like the way my car look with my new HU which took and hour to put in

not good enough for the price

Written By sureshotsniper, old hickory, tn on Sunday, January 25, 2009
Crutchfield Customer Review (What's this?)
 
This works for what it is... but the buttons are not as nice as the ones that are in the car. Instructions are for manual climate controls as someone has said... so read instructions and use common sense (that's so lacking in the world now-a-days it's almost a super power).

Paint is poor... a very light, easily scratchable surface... I painted mine black (and all the other center panels as well)... and it's still good.

For the price, it should have been nicer... but when it's all you got, it has to do.

Metra 99-7503 Factory Integration Adapter

Written By Ryan, Tracy, CA on Friday, January 02, 2009
Crutchfield Customer Review (What's this?)
 
Metra OEM Adapter for 2005 Mazda 6

WARNING! Crutchfield supplied installation instructions are NOT for 2005 6's electronic climate control system.
The instructions are for the MANUAL climate control knobs. Note that there are NO screws behind the electronic control dials to remove (therefore, no reason to remove them). If you remove the dials, they will not stay in after re-installation.

Also, the paint on the unit is not as thick as Mazda's so be careful not to scratch. And the the hazard light button is cheesy.

Other than that, it fit the dash good, and the stereo fit securely. It's not worth the list price, but I got it for 1/2 price with the purchase of a stereo, and it is worth that.

Only Choice for Mazda 6 Owners

Written By marting007, USA on Friday, December 26, 2008
Crutchfield Customer Review (What's this?)
 
Unfortunately if you are a Mazda 6 owner the Metra Kit is going to be your only option to fit an aftermarket unit.

The kit isn't terrible, but not great for the price. Fortunately Crutchfield had a deal where the kit was sold at 1/2 price if you bought a unit at the same
time. My son and I did the installation ourselves in his car. The total installation time took around 5 hours, but we were also installing a new CD/reciever unit and a steering wheel control unit at the same time. This was also our first time installing a car stereo system, so we were probably as slow as you could get.

The Good: The kit was fairly simple to install (after we got past the poor instructions, noted below). The panel looks very nice and matched the interior very well. In my son's 2005 Mazda 6 there were none of the problems with gaps or the panel not seating properly as noted by other reviewers.

The Bad: The instructions were not so great, and totally left out several important steps (like setting the gear shift lever in the neutral position in order to remove the factory panel). The instructions also never mentioned re-installing the air vent panel back on the Metra unit, but it was obvious that it had to be done. My biggest dissapointment as other reviewers have mentioned were the poor quality of the buttons on the panel. The center A/C button was nearly impossible to use and has to be pressed very hard several times to get it to work.

Metra 99-7503 Factory Integration Adapter

Written By franks, Reston, VA on Monday, November 10, 2008
Crutchfield Customer Review (What's this?)
 
I believe that this product is the only alternative for installing aftermarket radios for a mazda 6. With that being said, the look was very close to the original panel but I felt the quality was lacking. The paint or finish straches very easily, which I discovered during installation. The buttons are also more squared off than the original and I noticed that the AC and Defrost buttons were reversed from the original panel. Everything still worked correctly but this may be an issue for some people. The quality provided is definetely not worth the price. I gave it a 3 because I believe it is the only alternative.

Looks very similar to stock

Crutchfield Customer Review (What's this?)
 
I got this w/ my
Alpine CDA-9884 HU
and it looks just
like stock. I do
have some negatives
though; I don't know
if it's fully this
things fault or just
that there isn't
much room behind my
HU, but I had a
heckuva' time
getting my HU to
fully fit in my
dash. There were so
many cables that it
took my over an hour
to get my HU to fit
in my dash nicely.
So i think this is
not really a knock
on this part, but
just something to
keep in mind. Also
some of the screw
holes didn't match
up perfectly and I
had to bend the
plastic to get
things to line up
(not a huge issue).

My biggest complaint
is that having my HU
in my car now for 3
days I am pushing
this console thing
in because it looks
like it's coming out
of the dash at the
top. This directly
relates to the
amount of room I
have behind the HU
and the wires
pushing out, but the
clips at the top
where this thing
clips into fell out
as soon as I tried
installing it.

When you have a
Mazda 6 there just
isn't much choice so
you're kinda stuck
with this high
priced unit.
