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 Heritage Behind the Toyota Yaris Family:
1. Toyota Starlet (1973 – 1999)
The Yaris lineage traces back indirectly to Toyota's small yet agile Starlet, which became an enduring favorite across international markets including Europe and Japan. Renowned for lightweight efficiency, compact dimensions, and spirited handling, the Starlet brought affordable, spirited motoring to the masses. Models like the Starlet GT Turbo (EP82 & EP91), with their potent turbocharged engines and nimble suspensions, remain revered benchmarks of performance hatchbacks from Toyota.
2. First Generation Yaris/Vitz (1999 – 2005)
Succeeding the Starlet, the Toyota Yaris—in Japan known as the Toyota Vitz—debuted as an advanced compact hatchback engineered for practicality matched by enduring appeal. Affordable but quality-rich interior appointments and a smooth-driving character earned global acclaim. Enthusiasts particularly appreciated special sporty versions such as Japan's Vitz RS, known for offering dynamic performance benefits in a compact package.
3. Second Generation Yaris/Vitz (2005 – 2010)
Further refining comfort, spaciousness, and efficiency, this generation explicitly embraced a global audience. Toyota enriched the model with improved styling, enhanced safety, and various performance-oriented trims that retained driver-friendly attributes sought by driving aficionados. Toyota continued offering performance variations like the RS trim, balancing practical family usability with responsive handling and increased engine vigor.
4. Third Generation Yaris/Vitz (2011 – 2020)
Significant advances in cabin comfort, vehicle dynamics, and safety marked the third-generation's evolution. With smoother lines and increased spaciousness, this Yaris appealed widely, yet performance variants preserved its enthusiast credentials. International markets enjoyed the introduction of variants like the Yaris GRMN (Gazoo Racing Masters of Nürburgring) launched in 2017, featuring limited-run exclusivity, powerful supercharged engines, and chassis refinements making it a highly coveted hot hatch.
5. Fourth Generation and Toyota GR Yaris (2019 – Present)
When the fourth-generation Yaris platform transitioned to Toyota’s advanced small-vehicle architecture, the introduction of the high-performance GR Yaris astonished enthusiasts worldwide. Co-developed with Toyota Gazoo Racing—acclaimed for prestigious motorsport programs—the GR Yaris broke from traditional hatchback design by merging genuine motorsport technology directly into its compact, muscular build.
Notably, the GR Yaris departed drastically from its stablemates by emphasizing lightweight construction and utilizing an advanced four-wheel-drive system inspired directly from Toyota’s ambitions in the World Rally Championship (WRC). Beneath its purposeful, aggressively sculpted body, enthusiasts found a remarkable combination of motorsport-derived elements including an aluminum intensive construction, a powerful 1.6-liter turbocharged three-cylinder engine producing 257–268 horsepower depending on the market, paired impressively with a sophisticated full-time GR-Four All-Wheel Drive drivetrain. This formula translated directly into impressive agility, responsive dynamic feedback, and thrilling acceleration, firmly cementing the GR Yaris’ status within contemporary enthusiast circles globally.
Enhancing the Automotive Experience with Modern Infotainment:
While the GR Yaris is fundamentally oriented towards driver pleasure and dynamic performance, the standard infotainment setup in some markets has faced criticism for offering limited functionality and connectivity. To address this, Brummstadt provides an enticing modern infotainment solution crafted specifically for Toyota GR Yaris models produced between 2019 and 2024. Offering broad compatibility, the Brummstadt head unit effortlessly integrates modern interfaces through both wired and wireless Apple CarPlay and Android Auto. This replacement solution maintains a sleek factory-look dash panel allowing a sophisticated technology center that feels organic and ergonomic within the vehicle interior.

Further enhancing driver and passenger connectivity is the available upgrade option offering high-definition 1080p cameras both front and rear, providing responsive recording capability, evidence for unforeseeable circumstances, clearer situational awareness, and peace-of-mind security both on track and public roads.
The infotainment integration brings more engaging features through USB-connected game controllers—allowing passengers, whether family or friends, to turn long road trips or traffic delays into immersive gaming sessions, thus introducing unique experiential elements not typically expected in the compact sports segment.
