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 Journey of the Subaru Impreza:
First Generation (GC, GF, GM; 1992–2000):
The inaugural Impreza debuted globally in 1992 as a replacement for the Leone. Subaru introduced it as a capable all-wheel-drive compact sedan and wagon with an optional front-wheel-drive platform initially offered in select markets. Enthusiasm surged following the launch of the performance-focused Impreza WRX series, acclaimed in motorsports for its balance, agility, and potent turbocharged boxer engines. The combination of compact size, practicality, and notable reliability made it globally appealing, immediately carving out a loyal following.
Second Generation (GD, GG; 2000–2007):
The second generation refined and expanded the segments in which the Impreza competed. Subaru embarked on enhancing the chassis rigidity, interior comfort, and safety technology while continuing the WRX and WRX STi performance heritage. The distinctive "Bug-Eye," "Blob-Eye," and later "Hawk-Eye" front-end styles emerged as enthusiast-favored classifications, becoming lasting symbols of Subaru's ability to combine practicality and spirited performance.
Third Generation (GE, GH, GR, GV; 2007–2011):
With an emphasis shifting to greater comfort and contemporary design without sacrificing the integral all-wheel-drive dynamic capability, Subaru repositioned the third generation Impreza toward wider appeal. The introduction of a more upscale interior, refined suspension tuning, and an increased emphasis on safety helped the car find favor not only among dedicated Subaru drivers but also among mainstream consumers seeking a practical, reliable, and safe compact vehicle. The performance-oriented WRX and STi versions maintained their legendary motorsport-inspired credentials, ensuring continued enthusiasm from dedicated performance communities.
Fourth Generation (GP & GJ; 2012–2016):
The fourth generation Impreza (sedan referred to as GJ, hatchback as GP) introduced Subaru's advanced new global-oriented platform, solidifying its stance as both a versatile compact and an economical alternative among segment competitors. Subaru responded effectively to marketplace demands by incorporating improved fuel economy, enhanced refinement, greater interior space, and comprehensive safety improvements—such as greater implementation of Subaru's EyeSight advanced driver-assist system introduced in later years of the generation. Engineered for a wider comfort appeal, the naturally aspirated 2.0-liter four-cylinder boxer engine provided commendable efficiency, contributing to lower operating costs, smoother driving characteristics, and reduced emissions in response to global market trends.
Diverse markets identified this generation by varying trim naming conventions but maintained similar foundational models. Internationally consistent trim options commonly ranged from practical and affordable base levels ascending through mid-level variants offering additional conveniences, with top versions receiving more indicated "premium," "limited," or "sport" designations depending on the region.
An Infotainment Integration Complementing Subaru's Practical Strengths:
Given Subaru's careful engineering for practical daily usability, the 2012-2016 Impreza generation can still significantly benefit from purposeful modern infotainment enhancements. As digital connectivity increasingly defines driving experiences, drivers seek advanced capabilities—often beyond the period-standard factory audio systems—encouraging aftermarket innovation. An exemplar of this innovation emerges from Brummstadt, an Australian company that provides driver-oriented infotainment solutions integrating smoothly into Subaru’s notably practical and comfortable cabins.
Brummstadt’s premium head unit kit suited to the Subaru Impreza (2012–2016 GP/GJ platform) distinctly addresses contemporary expectations. Drivers receive direct integration for both wired and wireless Apple CarPlay and Android Auto systems. Commonly relied-upon navigation applications—such as Google Maps, Apple Maps, or WAZE—gain direct, simplified connectivity access.
Practical scenario visualization highlights advantages clearly: Consider a group dining with friends or family at an unfamiliar location; inputting a friend’s address via a smartphone beforehand conveniently transfers onto the head unit when entering the vehicle, appearing clearly accessible on the screen with minimal distraction or delay. This intuitive interaction significantly diminishes driver tension—creating harmonious, efficient, worry-free travel between destinations.
In keeping with contemporary safety and ownership preferences, the unit notably accommodates upgrade options for combined 1080p High Definition (HD) front and rear cameras, offering increased visibility and recording capability—beneficial for navigating tight urban spaces or providing video recording assurance in unforeseen traffic circumstances.
Entertainment possibilities extend beyond audio entertainment into dynamic scenarios that passengers indulge in through integrated USB ports. Multiplayer gaming via joystick connections to the infotainment display transforms ordinary trips into memorable, engaging occasions; passengers—young or mature—will find interactivity captivating, effectively reducing monotony on lengthy journeys.
Moreover, integrated voice-activated smart assistant functionalities provide intuitive command-based convenience, further extending practicality. Simple voice commands to Apple’s Siri or Android Auto’s Google Assistant handle tasks like navigating efficiently, managing calls hands-free, adjusting playlists, or even remotely interacting with smart home devices—such as activating home lighting—prior to arrival, offering reassurance and convenience at the concluding stages of each journey.
