Our take on the Metra 99-7507 Factory Integration Adapter

You bought a 2006-up 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 single-sized (2" tall) stereo in the Mazda's dash panel, while maintaining all heating, ventilation, and air conditioning controls.

Not quite right

Nick from Baltimore, MD on 5/13/2013

Crutchfield Customer Review (What's this?)

I had to make alterations to the holes for my climate control knobs. I was told this was just a defective kit. I could wait for another one to be shipped or make alterations for it to fit.

Pros: Makes the switch from the factory radio near seamless.

Cons: The kit was defective and would not fit over my climate control knobs so I had to use sandpaper to make the holes bigger to fit the climate control knobs. Also no silver trim on the side like the factory piece that was removed.

It works

Crutchfield Customer Review (What's this?)

I read lots of negatives on the adaptor. The buttons do seem to be a little not as smooth as the originals. They do all work however and we will see about the durability over time. Everything fit togather well and the connections were all straight forward.

Pros: It is not a wow but it is o.k. for the purpose intended.

Cons: I did have to sauder a wire back togather on the small back light that came lose. Not a big deal

Crutchfield Customer Review (What's this?)

A total piece of junk! It is a shame that Crutchfield has to do business with this company. I don't know where this was manufactured, but it had to come from a 5th world country. Most items of this nature are laser cut. I think this was cut by a chainsaw. There is nothing to describe how cheap the switches are. The orginial one that was sent didn't work worth anything. I was overnited a second one and they work, but not like the factory switches. Cheap,cheap,cheap! The OEM plate had a "chrome" strip on both sides to match the rest of the car. Not this piece. The knobes are suppose to fit in the hols. Not this one. It is to bad that someone can't design a kit to replace the OEM radio and still use the OEM cover. The folks at Crutchfield really went out of their way to make thing right.



just ok

the dash kit works fine. it is ugly and looks very out of place. stock dash has the silver trim down the side. the dash kit does not!! it did not fit very well either. very cheap built!!



What's up with the buttons?

Elias M from Winter Park FL on 11/9/2010

Right off the batt, bad quality. For this price, I was expecting a nice piece of equipment. Oh, it does the job it's supposed to do, in short it holds an aftermarket radio, but that is where the pros end. If the price were less, then I would say it's a good bargain. But for the price, in my opinion, it is a poor value. All the buttons and knobs are flimsy and feel very cheap. The hazard button is difficult to press, and feels like it's going to break everytime I push it in. Who cares about the hazard button? I didn't until I installed this thing. The A/C control knobs feel like they were made for a little tykes baby toy. Who cares about A/C knobs? I didn't until I installed this thing. The lights on it are distractingly bright when driving at night. It's all the things I didn't care about that are now making me wish I hadn't purchased this thing. But what other choice do I have? Next time, custom installation. I have nothing against metra, but come on guys, a little workmanship here.



Are you joking?

Crutchfield Customer Review (What's this?)

I can't believe that an installation kit that costs this much is so cheap and flimsy. The buttons are cheaply made. They feel nothing like the original mazda buttons. The hazard button is almost impossible to press, and it feels like a cheap piece of plastic. Nowhere near as nice as the stock mazda buttons. The knobs are also cheaply made, they don't click into place like the stock knobs do, neither do they have the nice rubberized grip or the chrome bezel that the stock ones do. The led lights are not the same color or quality. They are almost blinding when it's dark out, and do not look attractive at all. Overall about the only thing that does match is the color and texture, but any part that moves is just poorly made. I really can't believe that this product costs this much. I would highly recommend you spend $500 or $600 and get the original piece customized instead of wasting your hard earned money on something this poorly designed, and poorly made.



Overall decent

Crutchfield Customer Review (What's this?)

Pros: It works, the color is extremely close to factory and makes installation a breeze Cons: Button is disappointing, the hazard switch is hard to press. The A/C, air circulation and defrost button's are 'cheap' looking and seems bigger than the factory ones. Also the lightbulb that is used for lighting the 3 bottom circular adjustment knobs(not sure what else to call it) appear more orange rather than red. Does not have the silver lining on the side of the dash like the factory mazda 07 has so appears to be not as OEM as it otherwise would.

Vehicle Compatibility: The Metra Turbo Kit 2 (99-7507) is designed specifically for 2006-2008 Mazda 6 vehicles. The 99-7507 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 (black) 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 control knobs and 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 (99-7507) 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).
