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.

Historical Journey of Mazda 323/Familia Through the Decades:
The Mazda Familia lineage has roots dating back to 1963 with the original first-generation model. Known affectionately simply as Familia in Japan, it quickly set a benchmark with practical, reliable transportation that was accessible and pleasing to drive. Successive models throughout the ‘70s and ‘80s elevated its carefully balanced formula, bringing accessible compact sedans, hatchbacks, and wagons into markets worldwide under different names; notably Mazda 323 in Europe and Australia, and Mazda GLC ("Great Little Car") through the late 1970s and early 1980s in North America.
A prominent turning point in Mazda Familia/323's journey came in the 1990s. The BG series (1989-1994) cultivated a loyal following due to its agile handling, sharp design, and sportier personality. Particularly appreciated for its dependable mechanics and rewarding drive, it laid the framework for the Familia's distinctive reputation in compact car markets.
The BH-series (1994-1998) carried forward these strengths, bringing finely tuned road manners and an expanded range of engine and trim options. Compact yet practical, this generation maintained its predecessor's approachable personality—ultimately paving the way for the acclaimed BJ series (1998-2004).
Mazda BJ-Series (Mazda 323 / Familia / Protegé - 1998-2004):
Beginning production in 1998, the BJ Familia—which Australians and Europeans recognize as the Mazda 323, and Americans as the Mazda Protegé—was designed around Mazda's prevailing ethos of driving engagement, mechanical refinement, and versatile practicality.
The BJ models proved popular for a thoughtful blend of reliability, economy, and enjoyable driving dynamics. Offered in sedan, hatchback, and wagon variations internationally, these models featured a clean and modern profile; interiors emphasized sensible ergonomics and quality materials uncommon at the time within its class. The BJ range stood out through robust build quality, simple yet durable engineering, and commendable ride comfort—attributes still fondly recalled by owners globally.
Mazda Familia BJ underwent a significant mid-cycle revision known as BJ II in 2001, resulting in updated aesthetic elements, enhanced interior refinement, and upgraded safety features. The BJ II range raised the bar by introducing modern touches, enhanced materials, sharper exterior styling accents, and importantly—the introduction of sportier trims such as the SP20 hatchback variant prominent in the Australian and New Zealand markets.
The SP20 hatchback elevated the Familia experience through carefully considered upgrades: a lively 2.0-litre four-cylinder engine, refined suspension tuning, sport-oriented interior features, and distinct exterior styling (alloy wheels, aerodynamic enhancements, and subtle visual cues). It successfully struck a balance between daily usefulness and spirited driving.
