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 Evolution and Legacy of the Toyota Corolla:
First Generation (E10, 1966–1970):
The Corolla debuted as Toyota's answer to consumer desire for affordable, efficient, yet reliable everyday transportation. Simplicity and integrity quickly positioned it as a favored, accessible vehicle, laying down a foundational template—small size, economy, durability—that future generations would carefully continue to align with.

Significant advancements characterized each subsequent generation: enhanced interiors, improved mechanical reliability, new body styles, and upgraded features. Notably, the third generation (the E30 model, 1974–1979) was especially cherished due to robust build quality and unprecedented fuel economy, further solidifying the Corolla’s image of resilience and dependability—traits highly desirable during oil crises and uncertain economic eras.
Fifth and Sixth Generations (E80 and E90, 1983–1992):
Refined engine technology, contemporary styling, practicality, and versatility defined these generations. Basic cars evolved into more comfortable, practical family transport options. The renowned AE86 variant from the E80 generation (1983–1987) gained an enduring legacy through motorsports and drifting enthusiast circles worldwide, transcending its humble base-model identity.
Seventh and Eighth Generations (E100 and E110, 1992–2002):
By the mid-90s Corolla was established globally as a trusted standard for compact sedans—efficient and comfortable without being overly complicated. Notably, the E110 generation marked a cultural highpoint: widely recognized internationally as among the most robust and trouble-free vehicle ownership experiences available, its stellar reputation significantly boosted global Corolla sales and reinforced confidence in the model.
Ninth Generation Corolla (E120/E130, 2002–2007):
Arriving in 2002, the ninth-generation Corolla continued this tradition of thoughtful evolution and subtle refinement. This iteration showcased smoother exterior styling lines and larger dimensions, providing enhanced interior space and cabin comfort compared to predecessors. Notably durable construction standards persisted, alongside updated engine technologies, improved ride comfort, smoother transmission systems, and reassuring safety enhancements. Its popularity derived from precisely blending practicality, reliability, and affordability, endeared it greatly to diverse customer demographics globally. Available globally, the vehicle presented minor distinctions by market: in Japan known simply as the Corolla in several variants; offered as the Corolla Altis within Southeast Asia; and known as Corolla Sedan and Hatchback in Australia and Europe, with minor cosmetic and feature adjustments tailored to regional preferences. High-quality manufacturing contributed to worldwide recognition for unaffected reliability, comfort, and economy—hallmark traits firmly cemented during this period.
Complementing its reliability, drivers frequently sought modern infotainment and connectivity solutions desired in more contemporary vehicles. Brummstadt addresses this practical and popular preference through their specialized premium infotainment head unit, distinctly tailored for Toyota Corolla models of this generation (2002-2007). Integrating seamlessly into existing dashboard arrangements, the unit features intuitive interfaces and immediate connectivity capabilities, supporting both wired and wireless Apple CarPlay and Android Auto—directly satisfying modern drivers’ multifunctional, connectivity-rich requirements.

Such arrangements simplify planning and support confident, distraction-free driving, notably alleviating navigation-related stress.
Significant to enhanced security and convenience, the optional 1080p high-definition camera upgrade provides front-and-rear recording capabilities enabling increased road visibility, improved maneuvering accessibility, and invaluable documented event evidence, if necessary.
