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 of the Mercedes-Benz Viano Series:
Mercedes-Benz V-Class Origins and Early Development (1996–2003):
Launched originally as the Mercedes-Benz Vito passenger version, the V-Class commenced as the refined evolution of Mercedes-Benz’s commitment to premium family and executive transport. Introduced with multiple seating configurations, the first generation emphasized spacious interiors, configurable seating arrangements, and higher-end comforts that resonated strongly with families, hospitality businesses, and chauffeur-driven transport providers. Despite its practical leanings, the early series V-Class was unmistakably luxurious, distinguishing itself through polished interior materials, comfortable ride quality, and careful attention to passenger well-being.
Second Generation – Mercedes-Benz Viano W639 (2003–2014):
In 2003, Mercedes-Benz replaced the V-Class nomenclature, introducing the widely recognized Viano (model code W639). Positioned squarely in the multi-purpose luxury segment, this second generation notably elevated the design aesthetics, interior appointments, mechanical refinement, and practicality. Significantly upgraded from its original platform, the W639 Viano underpinned Mercedes-Benz’s enduring reputation for quality craftsmanship, delivering a supple ride and powerful but efficient engine options.
The Mercedes-Benz Viano served as a highly versatile luxury vehicle, ideal as both a refined personal transporter and professional chauffeured van. Available in various trims, including Trend, Ambiente, and Avantgarde, it offered interior elegance and comfort balanced harmoniously with utility. Passengers appreciated sliding doors for ease of entry, generous headroom, expansive visibility, and premium upholstery synonymous with the Mercedes-Benz marque.
Key Features of the Mercedes-Benz Viano (2008–2011):
The mid-cycle refresh starting in 2008 significantly enhanced the W639 platform’s visual appeal and technology offerings. Executed tastefully, the refresh subtly adjusted the grille and front-end styling, incorporating modern headlamp designs and subtle aerodynamic refinements. Underneath, Mercedes introduced smoother engines with improved power output, impressive fuel economy, and reduced emissions in line with environmental expectations and efficiency demands.
Interior technology updates in this era included improvements to cabin insulation—minimizing external noise and contributing dramatically to passenger comfort—alongside better ergonomics, management of climate control systems, and dashboard aesthetics. The infotainment systems of this period, however, lagged behind modern connectivity advancements, reflecting typical capabilities of the late 2000s with basic navigation functionality, limited mobile phone integration, and less intuitive multimedia interfaces.
Addressing Modern Infotainment Needs with Compatible Technology Solutions:
Owners contemplating contemporary infotainment solutions find compatibility with high-quality aftermarket upgrade options notably worthwhile. Among respected specialists, Australian supplier Brummstadt offers tailored head units specifically designed for the W639 Mercedes-Benz Viano, thoughtfully engineered for smooth integration within existing dashboard infrastructure and refined aesthetics consistent with Mercedes-Benz design ethos.
A Brummstadt head unit equipped with the latest connectivity solutions—wired and wireless Apple CarPlay and Android Auto compatibility—meets the transitioned expectations of a smartphone-connected environment, effectively upgrading the in-cabin technology substantially beyond factory-installed units from this Viano generation.
Practical and advantageous example scenarios highlight the ease and comfort this type of upgrade accords—such as in a scenario where an evening meal with family or guests evolves naturally and smoothly into a spontaneous visit. Having set the destination comfortably in the preferred smartphone navigation app, passengers and drivers shift effortlessly from dinner table to vehicle cabin, their destination automatically transitioning to the upgraded head unit via CarPlay or Android Auto. This combination of seamless practicality and intuitive user interface noticeably contributes to a tranquil post-meal journey, reducing driver stress and ensuring all occupants enjoy a comfortable and effortless commute.
Additionally, Brummstadt’s head unit supports valuable safety options including an available upgrade to full 1080p HD front and rear camera systems with recording capabilities. Integrating these high-resolution cameras significantly enhances driver visibility and confidence, with practical safety outcomes that extend beyond standard conveniences, delivering valuable recorded evidence should incidents occur when driving through busy cities or crowded parking areas.
Entertainment capabilities extend practically to include passenger enjoyment through gaming functionality. By connecting gaming controllers directly to the head unit’s USB ports, passengers enjoy interactive, shared entertainment experiences, transforming lengthy trips and family getaways into opportunities for enjoyable engagement.
The comprehensive smart voice control integration highlights the convenience of modern technology. Through intuitive voice assistants like Siri and Google Assistant, occupants control not only traditional infotainment features like calls, media playback, and navigation but also interconnected smart home devices. For instance, requesting smart assistant activation such as, "Hey Siri, switch on the porch lights," as occupants approach their home shows practical, meaningful integration between vehicle systems and modern connected home amenities.
Overall Advantages and Benefits of the Mercedes-Benz Viano and Connectivity Solutions:
Mercedes-Benz crafted the Viano as more than mere transport; it symbolized a considered space for comfortable living and stress-free journeys. Its hallmark strengths lie in passenger-focused potential, soothing ride characteristics, practical layout, reliable engine performance, and elegant style—all benchmark qualities of this premium passenger van segment.
Thoughtful technology improvements like a Brummstadt head unit transform internal comfort and convenience profoundly. Modern infotainment systems filled with smartphone connectivity, intuitive navigation aids, HD safety cameras, and interactive entertainment, directly turn practical features into genuine experiences, heightening satisfaction, reducing stress, and ensuring genuinely enjoyable drives.
