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 Context and Evolution of the Holden Colorado:
First Generation: The Chevrolet S-10 Roots (Global - Early 1980s to 2004)
The history of the Holden Colorado begins overseas with America's Chevrolet S-10 in the early 1980s, a compact pickup tailored for city-sized utility and efficiency. Its simple yet rugged design, capable drivetrains, and practicality earned a loyal global following. General Motors successfully adapted and marketed this robust platform internationally under several brands; notably, in certain South American, African, and Southeast Asian markets, it became the Chevrolet S-10, GMC Sonoma, or Chevrolet LUV (Light Utility Vehicle).
Second Generation: Holden Rodeo and Colorado RC (Australia, Pre-2012)
In Australia, the legacy began under the well-known Holden Rodeo brand (originally launched in 1980), marketed as a dependable, no-fuss utility appealing strongly to tradespeople and rural communities. The Rodeo evolved through generations of refinement, each receiving improved power, comfort, and safety enhancements. Beginning in 2008, Holden adopted the global "Colorado" name in Australia, replacing the Rodeo entirely, and thus began the local market transition into the next phase of the popular ute.
Third Generation: Colorado RG Series I (2012–2016)
The RG marked a decisive transition, moving Holden's ute market position more directly against rivals with increased refinement, vastly improved towing capacities, significant road manners, and more sophisticated cabin comforts. In the Australian and New Zealand markets, the RG Colorado series elevated Holden's image and mainstream popularity significantly through a combination of robust diesel performance, practical interior accommodations, and enhanced styling cues from Chevrolet’s global design language.
Holden Colorado RG Series II (2017–2020) and Later Variants (2020–2022)
From 2017, the Series II thoroughly refreshed the Colorado, bringing major improvements in refinement, cabin quietness, ride quality, and driver assistance technology. The Z71 variant particularly gained a reputation for its elevated styling and premium interior enhancements, targeted towards buyers seeking comfort and distinctive appearance alongside traditional ute functionality. LS, LT, and LTZ trims offered varying balances between rugged dependability, practical interior features, and sophisticated tech conveniences, attracting a diverse customer base unified by a need for reliability and clear practical advantages. From 2020 until 2022, the Colorado further refined minor exterior details, interior material upgrades, and advanced infotainment system offerings, maintaining popularity by consistently evolving to match consumer expectations.
Holden and Chevrolet Branding Globally
Internationally, GM's dual-brand strategy prominently marketed the Colorado wearing Chevrolet badges elsewhere, particularly popular in Southeast Asia, South African, and South American markets. Though badging differed, these trucks closely mirrored Australia's Holden Colorado RG in specification, trim levels, and available technologies, highlighting the global appeal and practicality behind GM’s platform strategy.
