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 Honda Jazz (Fit) Models:
Honda Jazz GD (2001-2008):
Launched at the dawn of the new millennium, the first-generation Jazz captured immediate attention with its inventive "Magic Seat" system. This flexible seating allowed rear seats to fold effortlessly or lift vertically, instantly creating substantial cargo room. Compact outer dimensions combined with unexpectedly vast interior space swiftly endeared it to city dwellers and compact-car buyers. Throughout Europe, Asia including Australia, and Japan, the model quickly garnered acclaim for fuel efficiency combined with versatile practicality.
Honda Jazz GE (2008-2013):
The second-generation Jazz retained its compact proportions yet modernized styling, sportier handling, and improved refinement overall. Launched with a sleeker body and upgraded cabin materials, the GE-series Jazz became popular among young families and urban drivers valuing both practicality and efficient commuter driving characteristics. Notably, this series improved upon the flexible seating arrangement's convenience, safety measures, and enhanced suspension systems to ensure comfortable, dynamic handling.
Honda Jazz GK (2014-2018):
The third-generation model—commonly recognized as the GK series—saw considerable advancement in function, technology, ride comfort, and interior refinement. Honda appropriately reinforced the Jazz’s established traits of flexible practicality, roomy interior, and intelligent packaging. Its crisp-edged exterior design conveyed modern, urban sophistication, while a more refined ride quality and engaging handling ensured attraction beyond mere practicality. Cabin design improvements made it feel significantly more premium, featuring enhancements such as improved dashboard materials, quality tactile surfaces, and an intuitive internal design layout. This Jazz generation demonstrated Honda's commitment to safety, introducing options for greater driver-assistance features, positioning this variant as forward-thinking and conscious of evolving customer demands in international markets.
Across various international locales—including Europe, Australia, and Asia—the Jazz GK remained consistent in design fundamentals, preserving the model’s recognizable styling cues and key features. Known in North America and Japan as the Honda Fit, minor detail variations existed among regions, yet core attributes of clever packing and practicality persisted to popular acclaim globally.
Product Integration with Brummstadt’s Premium Head Unit:
While capable from the factory, the Honda Jazz GK models (2014-2018) greatly benefit from contemporary technology options that better align vehicle capabilities with modern consumer preferences. To address this, Brummstadt offers a meticulously compatible premium head unit designed explicitly to integrate straightforwardly within the Jazz’s standard dashboard and electronics architecture.
Brummstadt's unit introduces high-level connectivity through both wired and wireless support for Apple CarPlay and Android Auto, raising connectivity to modern standards. Using popular navigation tools, like Google Maps or WAZE, not only significantly improves daily travel convenience, but also seamlessly complements owners’ daily routines. For example, during a pleasant dinner outing with close family or friends: the next destination is set on a smartphone map application beforehand. Subsequently, with effortless wireless smartphone pairing, the planned route appears clearly and promptly on the head unit as journeys commence. This integration ensures continuous navigational clarity, offering confidence, reduced distraction, and comfortable transitions from setting to setting, significantly refining the ownership experience.
Also accessible is an optional 1080p HD camera upgrade providing both front and rear views, ensuring improved visibility during maneuvers, simplifying tight city parking, and providing valuable recorded output in the occurrence of unfortunate events on the road—all crucial for modern urban driving scenarios.
Brummstadt also delivers engaging entertainment beyond traditional audio functions: through USB connectivity, intuitive gaming controllers paired to the premium head unit allow occupants the enjoyable possibility to engage together during rest periods or stationary times, converting cabin downtime into positively memorable experiences for all occupants, particularly during extended journeys.
Smart Voice Control capabilities constitute another thoughtful dimension. Utilizing voice-activated assistants such as Google Assistant or Apple's Siri allows safer, more seamless interaction with media, navigation assistance, telephone communication, and integrated home-connected devices. A scenario where the user, upon nearing home after sunset, safely dictates commands such as "Hey Siri! Turn on the porch lights," exemplifies perfectly how intuitive automotive technology genuinely improves daily life choices—supporting and blending seamlessly into daily lifestyle convenience and modern connected living.
