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.

The Holden Barina, produced between 2011 and 2016 (TM Series), stands as the sixth and final generation of Holden's beloved compact hatchback series. Renowned in Australia for its spirited design, efficient urban performance, and engaging handling, the Barina was embraced by drivers seeking a reliable, stylish, and economically practical car.
Historical Journey of the Holden Barina:
First Generation - MB/ML Series (1985-1988)
The Barina debuted in Australia as a rebadged Suzuki Swift, quickly earning popularity for its compact dimensions, fuel economy, and affordability. Particularly favored by younger drivers, it set the stage for the model’s future successes.
Second Generation - MF/MH Series (1989-1994)
Adopting the European Opel Corsa as its foundation, this series introduced sleek European styling and improved comfort, winning acclaim for blending practicality with continental refinement.
Third Generation - SB Series (1994-2000)
Continuing the Opel lineage, the SB series enhanced the model’s agility and safety features, such as airbags and reinforced structures, solidifying its reputation for reliability and driver confidence.
Fourth Generation - XC Series (2001-2005)
With the XC series based on Opel’s Corsa C, the Barina reached new heights in comfort and build quality. Its refined ride, interior ergonomics, and increased safety features earned enduring appeal among urban commuters.
Fifth Generation - TK Series (2005-2011)
Holden's strategic shift to GM Daewoo’s platform (Chevrolet Aveo/Kalos) marked a new direction, emphasizing affordability and practicality. Despite initial skepticism, it maintained strong sales through its balance of price and performance.
Sixth Generation - TM Series (2011-2016)
This final generation, known globally as Chevrolet Sonic/Aveo, delivered marked improvements in safety, design, and driver enjoyment. Its expressive styling and dynamic stance set it apart, supported by a capable 1.6-liter petrol engine (85 kW, 114 hp) known for responsive urban driving and efficient highway cruising.
Holden Barina vs. Holden Barina Spark:
During this period, Holden also offered the smaller, city-oriented Barina Spark (MJ Series, 2010-2015), derived from the Chevrolet Spark. While both shared compact philosophies, notable distinctions defined their respective roles:
- Engine & Performance: The Barina TM’s robust 1.6-liter engine provided superior power and highway comfort compared to the Spark’s smaller 1.2-liter engine, designed predominantly for city use and economy.
- Size & Interior Space: The Barina TM was roomier, offering increased passenger comfort and cargo versatility, while the Spark prioritized ease of parking, compact dimensions, and agility in tight urban environments.
- Styling & Target Audience: Barina TM's bold, mature styling and refined interior targeted a broader demographic, whereas the Spark appealed to younger, budget-conscious drivers seeking youthful design and high urban maneuverability.
