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 Context of the Holden Colorado 7:
Tracing the Colorado 7’s roots offers insight into the strategic evolution of General Motors’ global SUV lineup. While the "Colorado" nameplate extended Chevy’s pickup series, the Colorado 7 presented a meaningful evolution—engineered specifically on the robust Colorado pickup platform. General Motors targeted markets such as Australia, New Zealand, Thailand, and South Africa, where there was significant demand for durable, spacious, diesel-powered SUVs. Known primarily as Holden Colorado 7 in Australia and Chevrolet Trailblazer elsewhere, the model entered production in response to increasing consumer preference for versatile seven-seater vehicles capable of reliable performance both on- and off-road.
In Australia, the Colorado 7 boasted variants such as the LT and flagship LTZ, offering rising levels of comfort and technological sophistication. This SUV gained appreciation for its powerful turbo-diesel engine and durable ladder-frame chassis, becoming a family favourite thanks to its unmatched practicality, capable chassis design, and adaptability to Australia's varied driving conditions.
Across global markets, Chevrolet marketed essentially identical models like the Chevrolet Trailblazer, thoroughly maintaining the same practicality, production quality, and functional strengths seen in its Holden counterpart, assuring universal appeal of this robust vehicle.
Design & Performance Advantages:
The Colorado 7 (2012-2016) was characterised by its reliable structure, featuring solid body-on-frame construction derived from its sibling—the Holden Colorado Ute. Its style remained robust yet contemporary, with subtle elements underscoring its strength and adaptability. Internally, thoughtful cabin design efficiently utilized the available space, providing comfortable seating for up to seven occupants alongside ample cargo flexibility.
The 2.8-litre Duramax turbo-diesel engine was at the heart of Colorado 7’s commendable performance, offering substantial torque alongside reliable towing capabilities. This engine paired effectively with a user-friendly six-speed automatic transmission, renowned for its seamless shifts, effortless acceleration, and commendable fuel economy. Such characteristics ensured suitability both for daily commutes in urban settings and adventurous family journeys over varied terrain.
Further complementing its versatility were genuine four-wheel-drive capabilities, strengthened suspension, and durable running gear built to endure the challenges posed by Australian and global roads. Its strong mechanical foundations—with body rigidity, robust components, and refined power delivery—made the Colorado 7 consistently popular among those seeking performance capability beyond typical urban SUVs.
Comfort and contemporary amenities aligned nicely to create a balanced interior experience: climate control, multiple power sockets, Bluetooth connectivity, and intuitive driving controls rendered the cabin well-suited to long-distance family travels or daily practical duties.

From a technological perspective, original factory audio and infotainment systems often represent an earlier approach to driver needs. A more advanced aftermarket head unit solution sharply elevates enjoyment, multimedia capability, and convenience, aligning Colorado 7’s reliable underpinnings with today's expectations of connectivity and digital integration. Upgraded premium head units featuring both wireless and wired connectivity to Apple CarPlay and Android Auto transform navigation, media robustness, ease of use, and the way passengers and drivers interact with the vehicle systems.
Selecting a premium infotainment system improves the spontaneity and convenience of the driving experience through real-time smartphone integration, clearer graphics, and sophisticated navigation interfaces. Drivers benefit from precision route guidance, simplified smartphone interaction, clearer audio reproduction, and intuitive operation without distracting complexity. Additionally, modern interface enhancements help emulate contemporary features found in the latest automotive releases, protecting vehicle desirability and sustained practical value.
Lighting the Way Forward:
Upgraded infotainment systems for the Holden Colorado 7 not only offer better multimedia performance, audio quality, and navigation support but also revitalise the overall interior feel by introducing advanced interfaces, vivid displays, and up-to-date software. These significant infotainment system enhancements deliver renewed satisfaction, confidence, and delight in every driving scenario.
