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.

Tracing back its lineage, the Silverado emerged from Chevrolet’s longstanding heritage of robust trucks, most notably carrying forward the essence of the iconic Chevy C/K pickup series. The original Silverado series debuted officially in 1999, marking Chevrolet’s leap into creating a dedicated premium truck model. Following the successful initial run of that first-generation platform, Chevrolet introduced a more refined and accomplished Silverado lineup in 2007—a transforming moment in the series’ evolution.
Silverado's second generation (GMT900, 2007-2013) notably strengthened Chevrolet’s appeal in a highly competitive segment. Praised immediately upon debut for impressive engineering refinements and its quieter, more comfortable interior, this Silverado elevated expectations previously held for full-size trucks. Bridging bold utility with daily driving comfort, the GMT900 Silverado combined precise road manners and substantial hauling capabilities with advanced comfort and interior ergonomics, laying the foundation for modern pickup practicality that caters equally comfortably to hardworking weekdays and leisurely weekends.
The 2007-2013 Chevrolet Silverado carried forward the core strength of its predecessor but significantly advanced in safety, technology integration, interior quality, and overall refinement. Buyers applauded the breadth of available choices, from durable and economical work-truck variants (WT) designed hardily for commercial duty, to distinctive and generously optioned LTZ trims, featuring leather upholstery, climate-controlled interiors, and premium Bose audio systems—indeed redefining perspectives on pickup-truck luxury.
Popular powertrain options further strengthened the Silverado’s allure, including reliable V6 entry-level engines, substantial V8 packages (notably the favored 5.3-liter V8 known for balance between performance and economy), and potent options such as the 6.0-liter and 6.2-liter V8 powerhouses. Silverado’s performance, versatility, and expressive designs consistently secured its place among favorite pickups across urban landscapes, rural backroads, construction sites, and highways alike.
Enhancing the 2007-2013 Silverado’s versatility and modern relevance, drivers today have access to premium aftermarket technology upgrades, exemplified by brands such as Brummstadt. Designed explicitly to integrate neatly within the Silverado’s existing dash arrangement, Brummstadt’s head unit replacement offers substantial improvements over original infotainment systems. Equipped with both wired and wireless compatibility for leading smartphone platforms—Apple CarPlay and Android Auto—the transformed usability and connectivity experience within the Silverado cabin dramatically upgrade day-to-day driving practicality, convenience, and enjoyment.
Imagine a scenario where after a comfortable evening dining out with friends or family, one conveniently programs the journey’s next stop or friend’s address into smartphone navigation apps. Once comfortably seated behind the wheel, the pre-selected route appears instantly and clearly displayed, smoothly synchronized from phone to dash via Apple CarPlay or Android Auto wireless connectivity. The eliminated hassle allows immediate departure without distraction, simplifying the transition from socializing to smooth onward adventures.
Further enhancing practicality and peace of mind, Brummstadt’s compatible head units offer integrated support for advanced optional accessories, particularly 1080p high-definition front and rear cameras providing clear recording-quality footage. This feature significantly contributes to driving confidence by continually monitoring driving conditions and road safety, providing added assurance and potentially essential documentation for unexpected events encountered during journeys.
Moreover, emphasizing enhanced passenger experiences on lengthy drives, the system also embraces entertainment through integrated USB connectivity. Backseat passengers discover a world of interactive gaming possibilities simply by plugging joysticks and controllers directly into USB connections, transforming tedious journeys into enjoyable interactive play sessions. This creative integration significantly contributes to memorable, joyful in-vehicle experiences for adults and children alike—making the Silverado ideal for long journeys, family trips, or weekend getaways.
Additionally, drivers and passengers benefit from intuitive smart voice control with integrated virtual assistant support. Compatible with leading assistants like Siri and Google Assistant, voice commands reliably manage infotainment/media selections, hands-free communication needs, precise navigation inputs, and even extend outward beyond vehicles. Approaching home or another destination, occupants can trigger connected home automation devices through a simple command—even a convenience as clear as requesting "Hey Siri! Turn on the porch lights," simplifying interactions between travel and home.
The 2007-2013 Chevrolet Silverado GMT900 already secured a formidable reputation through careful engineering, ample capability, reassuring reliability, refined driving dynamics, and thoughtful interior craftsmanship. Embracing precise aftermarket technology integration adds further layers of functionality, safety, and riding pleasure. Brummstadt’s thoughtfully integrated products complement existing strengths of the model, marrying original Chevrolet reliability and strength with innovative connectivity, enhanced safety awareness, engaging entertainment, convenient navigation reliability, and intuitive smart-home integration—unmistakably presenting Silverado ownership as an elevated expression of usability, pride, and sophisticated comfort.
