A Comprehensive REVIEW of the Mazda TK78-66-9U0C OEM Hub CarPlay and Android Auto Retrofit Kit

For years, I found myself increasingly frustrated with the capabilities of my Mazda’s infotainment system. While the car itself was fantastic, the native navigation felt clunky, and the lack of seamless phone integration was a constant annoyance. In an age where staying connected safely on the road is paramount, the absence of modern features like Apple CarPlay or Android Auto felt like a significant oversight, severely limiting access to crucial apps and voice assistants. It was a problem that absolutely needed addressing, as fumbling with a phone for directions or music selection isn’t just inconvenient, it’s a serious safety hazard.

Forethought Before Investing in a Vehicle Connectivity Upgrade

When considering an upgrade to your vehicle’s infotainment system, it’s essential to first understand why you’d seek such a solution. Drivers often look for these enhancements to modernize their vehicles, gain access to up-to-date navigation, and integrate their smartphones for calls, messages, and music more safely. The ideal candidate for a CarPlay and Android Auto Retrofit Kit is typically a Mazda owner from the 2014-2020 model years whose vehicle lacks these contemporary features but is otherwise in excellent condition, making an upgrade a more cost-effective choice than buying a new car. These are individuals who value convenience, safety, and access to a familiar smartphone interface while driving.

However, this specific upgrade isn’t for everyone. If you own a newer Mazda that already comes equipped with factory-installed CarPlay or Android Auto, then this kit would obviously be redundant. Similarly, if you’re not comfortable with a degree of DIY installation or paying a dealership to handle a firmware update and installation, an aftermarket solution that requires less intrusive setup might be a better fit, though often at the cost of seamless integration. Before purchasing, consider your car’s exact model year and compatibility with the Mazda Connect System, verify the required firmware version, and assess your comfort level with the installation process, whether you plan to tackle it yourself or seek professional help. Ensure you confirm the precise part number (like the TK78-66-9U0C OEM Hub) for your specific Mazda model to guarantee a perfect fit.

Introducing the Solution for Enhanced In-Car Connectivity

The product that truly revolutionized my driving experience is the Mazda Carplay and Android Auto Retrofit Kit, TK78-66-9U0C OEM Hub. This ingenious kit promises to upgrade your existing Mazda Connect System, bringing the powerful and user-friendly Apple CarPlay and Android Auto directly to your dashboard. What you get upon purchase is a genuine OEM hub (part number TK78-66-9U0C / 00008FZ34) along with the necessary wiring harness to integrate these modern features. Unlike generic aftermarket solutions that might look tacked on, this kit is designed to perfectly match your Mazda’s interior and existing controls, making it feel like a factory-installed upgrade rather than an add-on. It vastly surpasses the limitations of earlier Mazda infotainment versions by unlocking full smartphone mirroring and voice assistant capabilities.

This particular Carplay hub is ideal for owners of specific Mazda models, including the CX-3 (2016-2019), CX-5 (2016-2017), CX-9 (2016-2020), Mazda3 (2014-2018), Mazda6 (2016-2020), and MX-5 (2016-2020) who are seeking to modernize their in-car technology without investing in a brand-new vehicle. It is not for Mazda owners with much older models outside this range or those whose vehicles already have these features integrated from the factory.

Here’s a quick overview of its strengths and weaknesses:

Pros:
* Seamless integration with existing Mazda Connect System.
* Retains full functionality of original control knob and steering wheel buttons.
* Provides access to up-to-date navigation, music, and communication apps.
* Enables hands-free operation via Siri or Google Assistant.
* Offers faster charging capabilities for connected devices.

Cons:
* Requires a firmware update (version V70.00.21 or later) as a prerequisite.
* Installation, while manageable for some, can be time-consuming for novices.
* The connection for CarPlay and Android Auto is primarily wired, requiring your phone to be plugged in.
* Wire management during installation can be a bit tricky due to cable length.
* Some users report the wire gauge being slightly thicker than OEM, making tape wrapping challenging.

Deep Dive into the Features and Their Advantages

Having lived with the Mazda TK78-66-9U0C OEM Hub for quite some time now, I can confidently say its features have transformed my driving experience. Each component works synergistically to deliver a truly modern and safe in-car environment.

Seamless Integration with the Mazda Connect System

One of the most impressive aspects of this retrofit kit is its almost invisible integration. When I first considered upgrading, I was wary of a clunky, aftermarket feel. However, the TK78-66-9U0C OEM Hub slots perfectly into the existing Mazda Connect System. It utilizes the original screen and car’s architecture, meaning there are no additional screens or unsightly wires dangling about. This OEM-level fit and finish maintains the clean aesthetic of the Mazda interior, something I deeply appreciate. From a long-term perspective, this seamless integration has been a joy. It doesn’t feel like an afterthought; it feels like how the car should have come from the factory. This fidelity to the original design ensures that the user experience is consistent and intuitive, which is crucial for safety and enjoyment on the road.

Unlocking Apple CarPlay & Android Auto Functionality

This is, without a doubt, the core benefit. Prior to the installation of this Apple Carplay Adapter, my Mazda’s navigation was outdated and lacked real-time traffic updates. With CarPlay and Android Auto, I now have access to Google Maps, Apple Maps, or Waze, all with live traffic data and dynamic rerouting. This alone has eliminated countless frustrations during my daily commute and on long road trips. Beyond navigation, the ability to stream music directly from Spotify, Apple Music, or YouTube Music through the car’s sound system, manage phone calls, and send/receive messages via voice commands has been transformative. It means my phone stays safely in my pocket or on its charger, and all essential functions are accessible via the car’s display or voice control. The peace of mind knowing I have the latest maps and my entire music library at my fingertips, all while keeping my eyes on the road, is invaluable.

Retained Original Car Controls for Enhanced Safety

A significant concern with many aftermarket solutions is the potential loss of original car controls. Thankfully, this is where the Mazda Carplay and Android Auto Retrofit Kit truly shines. The existing Mazda control knob and the steering wheel buttons remain fully functional with the integrated CarPlay and Android Auto interfaces. I can effortlessly scroll through apps, select options, and adjust volume using the familiar physical controls I’ve always used. This aspect is incredibly important for safety, as it prevents the need to adapt to new, potentially distracting touch-screen only interfaces while driving. The tactile feedback from the knob allows for eyes-free operation for many common tasks, which is a massive advantage over purely touch-based systems. It’s truly a testament to the OEM design that this core functionality is preserved, making the upgrade feel natural rather than a foreign addition.

Enhanced USB Hub with Faster Charging and Connection Speeds

The new USB hub provided with the kit isn’t just about connectivity; it’s also a significant upgrade in terms of power delivery and data transfer. I’ve noticed a discernible difference in how quickly my iPhone connects to CarPlay upon starting the car – it’s almost instantaneous. Furthermore, the faster charging capabilities are a godsend, especially on longer drives where my phone previously struggled to maintain its charge while running navigation and music simultaneously. This improved efficiency means I arrive at my destination with a fully charged phone, ready for whatever comes next, rather than a device limping along at low battery. The reliable connection also means fewer dropouts or glitches, ensuring a consistently smooth user experience with both Mazda Carplay and Android Auto.

The Installation Journey: A Rewarding DIY or Dealer Option

One of the most talked-about aspects of this upgrade is the installation process itself. While the product description labels it as a “retrofit kit,” suggesting a degree of complexity, my experience, and that of many others, indicates it’s surprisingly manageable for those with a bit of patience and access to online tutorials. The first crucial step is the firmware update; my car required updating to V70.00.21 or later. I opted to have the Mazda dealership perform this initial firmware upgrade, which was a relatively inexpensive service that made the subsequent hardware installation completely stress-free. For the hardware installation, countless detailed YouTube videos walk you through the process of carefully unsnapping trim pieces, accessing the CMU (Connectivity Master Unit), and swapping out the USB hub. It took me about 45 minutes, taking my time to ensure every connection was secure and wires were properly routed. Someone more experienced could likely do it in 10-15 minutes. The kit even comes with foam sticky tape to wrap wires, minimizing any potential for rattles, which shows a thoughtful design. While the wired connection (as per the product description for the core product) might be a slight drawback for those hoping for fully wireless straight out of the box, it ensures a stable and reliable link for data and power. Managing the slightly longer cables from the display to the new hub did require a bit of strategic placement behind the glovebox, but it was a minor hurdle in an otherwise straightforward process.

Intelligent Voice Assistant Integration (Siri/Google Assistant)

Before this kit, using voice commands in my Mazda was a frustrating hit-or-miss affair, mostly miss. Now, with the seamless integration of Siri and Google Assistant through CarPlay and Android Auto, voice commands are not just a feature, they are a fundamental part of my driving. Whether I need to send a text, make a call, get directions, or simply change a song, a quick voice command handles it. The responsiveness and accuracy are leagues ahead of the old system. This hands-free capability is a massive leap forward for driving safety, allowing me to keep my hands on the wheel and eyes on the road at all times. It truly exemplifies how modern technology can enhance convenience without compromising safety.

What Other Users Are Saying: Testimonials from the Road

Having thoroughly researched various solutions online before making my purchase, I found numerous overwhelmingly positive user reviews for the Mazda TK78-66-9U0C OEM Hub. Many echoed my sentiment about the ease of installation, noting that while the prospect of disassembly might seem daunting, it’s surprisingly simple with the help of online video guides. Users consistently praise the seamless functionality once installed, often highlighting the immediate improvement in navigation and overall phone integration. The need for a firmware update is a common point, but most agree it’s a worthwhile, often simple, prerequisite for such a transformative upgrade. Overall, the consensus is clear: this kit delivers on its promise to modernize compatible Mazda vehicles.

Final Thoughts: A Worthwhile Investment for Your Mazda

The problem of an outdated in-car infotainment system is more than just an inconvenience; it can be a significant distraction and safety concern, pulling your attention away from the road for simple tasks like navigation or music selection. The Mazda Carplay and Android Auto Retrofit Kit, TK78-66-9U0C OEM Hub offers a brilliant and cost-effective solution to this modern dilemma. It’s a great fit because it fundamentally transforms your driving experience, providing access to essential smartphone features directly on your car’s screen, all while retaining the familiar and safe original controls. This OEM-level upgrade enhances safety, provides up-to-date functionality, and breathes new life into your beloved Mazda. If you’re ready to bring your vehicle into the modern age of connectivity, I highly recommend this retrofit.
