Frequently Asked Questions
Everything you need to know about this head unit
Connect the single RCA cable with the yellow plug (included in your package) to extend your Bluetooth signal. This cable doubles as both a camera input AND a Bluetooth/WiFi antenna extension. The two small blue wires attached are antenna boosters that significantly improve connection stability. This simple connection takes 30 seconds and resolves 90% of Bluetooth issues. Make sure it's firmly connected even if you're not using a rear camera.
Try these proven solutions:
1. Quick Fix: Settings → Apps → Z-Link → Disable → Enable → Open (repeat each use)
2. Check Cables: Use the data/charge USB cable (not charge-only)
3. Bluetooth Setting: Disconnect all other Bluetooth connections - CarPlay needs exclusive access
4. Factory Reset Z-Link: Find the pink 'RESET' app, restart, reconnect Bluetooth, then try Z-Link
5. Sound Issues: Switch audio source to 'AUX' or 'USB/AUX' in your vehicle menu
Most issues are resolved with step 1 or 3!
The processor differs between models: The 2/32GB has a 4-Core processor, while 4/64GB and 8/128GB models feature the powerful 8-Core Cortex-A55 processor. Combined with RAM differences: The 2/32GB model with its 4-Core processor and limited RAM may experience slowdowns with heavy multitasking. The 4/64GB with 8-Core provides smooth performance for most users - no lag, seamless app switching, and enough storage for maps and music. The 8/128GB with 8-Core offers maximum performance with its generous RAM allowing unlimited multitasking and massive storage for extensive media libraries. Think of RAM like your desk space - more RAM means you can have more apps open simultaneously without slowing down.
Absolutely normal! These head units are complete replacement systems with their own GPS antenna, microphone, and Bluetooth module. Your factory connectors for these features won't be needed anymore. The important connections are: main power harness, speaker outputs, and the yellow RCA cable (even if not using a camera - it extends Bluetooth range). Any leftover factory plugs can be safely tucked away. If you're unsure about any connection, our support team is here 7 days a week.
Z-Link updates are handled through system firmware updates. Go to Settings → System → System Update. If an update is available, download it to a USB drive (FAT32 format) and install. Important: Never download Z-Link APKs from unofficial sources - they won't work and may cause issues. If you're having compatibility issues with newer iOS versions, the disable/enable workaround (Settings → Apps → Z-Link) usually resolves them while waiting for official updates.
Consider your usage:
• 2/32GB (4-Core): Budget option - fine for basic use, but may lag with multiple apps due to 4-Core processor and limited RAM
• 4/64GB (8-Core): Sweet spot - smooth Android Auto/CarPlay, multitasking, and ample storage
• 8/128GB (8-Core): Premium choice - unlimited multitasking, massive storage, future-proof for years
Most customers choose 4/64GB for the perfect balance of performance and value. The extra RAM makes a huge difference in daily smoothness!
The yellow RCA cable's blue antenna wires also boost WiFi signal! Make sure this cable is connected. Additionally, try these tips: Position the blue antenna wires away from metal surfaces, check that your phone's hotspot is set to 2.4GHz (not 5GHz) for better range, and ensure the head unit's WiFi sleep policy is set to 'Never' in Settings → WiFi → Advanced. For best performance with wireless CarPlay, keep your phone within 1-2 meters of the head unit.
Go to Settings → Sound → Equalizer and adjust to your preference. For more volume, increase the 'Loudness' setting. The 4/64GB and 8/128GB models have superior audio chips that provide cleaner, louder sound. If you have an amplifier, use the RCA outputs for best quality. Also check Settings → Factory Settings (password usually 126) → Audio settings for additional gain controls. Remember: higher-spec models (4GB+) include premium audio components for noticeably better sound.
Yes! Most vehicles work instantly. If not, use the steering wheel learning app: tap the steering wheel icon, press each button on your wheel, and assign functions.

From Mazda 626 to Mazda 6: Evolution Along the Automotive Timeline
Mazda’s venture in the midsize category began long before the 2002 debut of the very first Mazda 6. Initially entering the market in 1970 with the Mazda Capella, globally known later as the Mazda 626, the company rapidly earned distinction for engineering thoughtfully designed, efficient, and reliable family sedans and wagons. Over numerous generations, each iteration progressively introduced enhanced refinement, comfortable interiors, and increasingly dynamic driving experiences, carefully elevating Mazda’s brand reputation. Notably, the final generation Mazda 626 concluded its run around 2002, transitioning seamlessly into the bolder and more dynamically attuned Mazda 6 lineup.
First-Generation Mazda 6 (GG Series: 2002–2007):
The Mazda 6 first emerged in 2002, signaling Mazda’s design renewal with engaging driving dynamics, modern styling, and significant advances in cabin ergonomics. Built upon the "Zoom-Zoom" philosophy, the Mazda 6's first GG Series strongly emphasized driving enjoyment and agility while meeting the practical requirements of everyday usability. Available in sedan, wagon, and hatchback configurations, its responsive handling, distinctive exterior, spacious interiors, and competitive performance granted the vehicle numerous accolades, carving out a loyal following among global drivers who valued driving pleasure alongside practicality.
Second-Generation Mazda 6 (GH Series 1: 2008–2009):
The Mazda 6 GH Series, launching around 2008, represented significant advances and notable enhancements compared to its predecessor. Displaying Mazda’s continued dedication to quality, innovation, and precise handling, the Series 1 GH introduced a wider, sportier stance combined with a more streamlined and aerodynamic form. Gasoline and diesel engine options offered increased power delivery, commendable fuel efficiency, and refinement, resulting in a rewarding overall driving experience. The interior also saw significant upgrades, with higher-quality finishes, intuitive dashboard control layouts, and improved sound insulation, fostering a comfortable, enjoyable journey environment. It achieved gracefully balanced handling dynamics—a hallmark Mazda trait—with sharper steering responses, better road isolation, and excellent chassis rigidity.
Mazda 6 GH Series 2 Update (Facelift: 2010–2012):
Launching as a refined update in 2010, Series 2 continued to develop the GH model's distinct strengths, focusing on subtle yet vital improvements. Externally, it received an updated grille, reshaped head and tail lamps, and refined body detailing, enhancing aesthetic appeal without diluting its original character. Inside, notable enhancements included higher-quality seat fabrics, incremental improvements in cabin ergonomics, and additional convenience specifications. Mazda improved NVH levels (Noise, Vibration, Harshness), cabin insulation, and suspension tuning, providing noticeably more comfort and refinement across road conditions. Engine optimization for efficiency and cleaner emissions stood central in Mazda’s objectives, with engines such as the 2.5-liter naturally aspirated gasoline offering spirited performance, seamless response, and daily drivability tailor-fit for mid-sized sedan expectations.
