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 Overview of the Smart Fortwo:
First Generation (1998-2007):
The Smart Fortwo began its life in Europe in 1998, initially as the “Smart City Coupe.” Developed as a collaboration between Mercedes-Benz and Swatch watchmaker Nicolas Hayek, it brought an innovative concept to the automotive landscape. Its pioneering short wheelbase allowed unparalleled ease in tight city spaces, appealing strongly to drivers navigating crowded streets where space was at a premium. Early Fortwos received acclaim for novel features such as fully interchangeable plastic body panels, compact dimensions, and outstanding fuel efficiency—establishing this small car as a novel solution for urban mobility challenges while gaining popularity across Europe's metropolitan centres.
Second Generation (2007-2014):
In its second iteration, the Fortwo evolved substantially with improved safety standards and enhanced comfort. A modest size increase provided marginally better interior space and comfort without compromising the iconic diminutive footprint. The upgraded engineering — particularly enhanced stability control, airbags, electronic assistance systems, and improved build quality — solidified its reputation as a robust urban choice. Throughout Europe, the United States, Asia, and Australia, this version further broadened the Fortwo’s appeal, especially where space was scarce.
Third Generation (2014-Present) - Focus: 2016-2020 Model:
The third-generation Fortwo began in 2014 and saw considerable innovation compared to previous versions. Between 2016 and 2020, it showcased a carefully crafted exterior design, characterized by sleek, modern contours and updated lighting elements. Its interior received substantial refinement, adopting higher-quality materials and upgraded standard equipment for comfort and practicality. With improved handling, quieter ride quality, strong braking performance, and stable dynamics, this iteration enjoyed a significant rise in boutique appeal and practicality. Its turning circle — famously tight — allowed drivers ease and confidence in city traffic scenarios, ensuring the Fortwo remained an exceptional vehicle for tight urban maneuverability.
Despite its compact stature, this generation distinguished itself with elevated infotainment options. However, the standard factory systems often lacked comprehensive smartphone integration, an increasingly significant requirement for modern driving connectivity.
Infotainment and Connectivity Enhancement—Brummstadt Head Unit Integration:
To address these connectivity desires comprehensively, owners of the Smart Fortwo models from 2016–2020 often seek premium aftermarket solutions. Brummstadt, recognized for tailored multimedia integration, offers high-quality head units explicitly designed to blend harmoniously into the existing Smart Fortwo dash configuration. The carefully engineered unit ensures intuitive smartphone connectivity with both wired and wireless Apple CarPlay and Android Auto capabilities, supporting an expansive assortment of popular media, communication, and navigation apps, including Google Maps, WAZE, and Apple Maps.

This smooth integration transforms navigating from restaurants to friends’ houses, cinemas, or scenic drives into a stress-free and straightforward experience, especially valuable in dense city environments with unpredictable conditions and frequently crowded streets.
Additionally, the Brummstadt head unit supports an optional 1080p HD camera system both at the front and rear, allowing clear video recording of driving events. For tight city parking spaces or urban environments littered with pedestrian activity, these cameras significantly improve vehicle visibility and provide reassuring clarity, while also conveniently offering documentation in case of unforeseen traffic incidents.
Beyond navigation and safety, pleased passengers—particularly during waiting periods or in parked scenarios—can enjoy multiplayer gaming experiences offered directly through USB joystick ports integrated within Brummstadt's multimedia unit. Whether awaiting appointments, during travel rest breaks, or merely passing the time while stationary, integrating entertainment directly within the car environment enhances passenger comfort and strengthens relationships through shared experiences.
A Smart Voice Control feature further extends the head unit’s convenience. Thanks to compatibility with commonly utilized smart assistants like Siri and Google Assistant, occupants easily manage navigation and media functions hands-free. Additionally, the capability for intelligent interaction with home automation devices presents a practical and appealing aspect. Simple voice instructions such as “Hey Siri, turn on the porch lights" make arrival sequences safer, easier, and more intuitive—evidence of thoughtful integration of automotive technology into daily routines.
