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.

Evolution of the Toyota Estima/Previa/Tarago Series:
First Generation (XR10/XR20; 1990–1999):
Developed amid changing global tastes, Toyota introduced the XR10/XR20 Estima in 1990 as a pioneering mid-engined van with futuristic, aerodynamic styling far ahead of its contemporaries. The van offered exceptional internal cabin flexibility, thanks to cleverly integrated seating arrangements and generous luggage room. Positioned as more than mere transportation, this initial version quickly became popular among families enjoying its smooth ride, stable handling, remarkable fuel efficiency, and distinctively dynamic silhouette. This generation rapidly established Toyota’s minivan blueprint of combining spacious interiors with compact, streamlined exteriors.
Second Generation (XR30/XR40; 2000–2005/2006):
Arriving in 2000, this second generation brought significant innovations, shifting from the unique mid-engine layout to a more conventional front-engine, front-wheel-drive (and available all-wheel-drive) setup. Known primarily as the Toyota Estima in Japan and Asia, Toyota Previa in Europe, and Toyota Tarago in Australia, the second-generation van appropriately adapted to varied markets and user preferences. Its sleek exterior lines hinted at sophistication and style, while thoughtful interior layout focused on enhanced passenger comfort and practicality. Powered by a range of fuel-efficient and refined four-cylinder and V6 engines, combined with improved suspension tuning, the second-generation Estima/Previa garnered appreciation with family-oriented buyers for its ride refinement, safety features, reliability, and comfort, becoming notably popular in international markets and praised for its cost-effective ownership experience.
Third Generation (XR50; 2006 onwards):
Building upon earlier successes, the third-generation Estima further sharpened its market proposition from 2006 onward. Launching with improved chassis dynamics, updated styling elements, heightened interior luxury fittings—including premium upholstery, advanced multimedia systems, and introducing beneficial features like side airbags and electronic stability control—Estima proved itself impressively balanced between economical, relaxed highway cruising and practical urban handling.
