    Compatible with the following vehicle models:

    • Jeep™ Grand Cherokee from 1999-2005
    If your Jeep is equipped with a factory reverse camera, you can maintain its functionality using a factory camera retention cable. This cable is not included and must be purchased separately. To find the right cable for your Jeep's model and year, please conduct a quick search online. If you have any questions, our dedicated customer service team is just a click away.

    Not sure if it fits? 📸 Send us a snap of your car and we’ll reply fast with what fits.

    Please note that even vehicles of the same model may have subtle differences. We are committed to ensuring compatibility and have carefully accounted for each vehicle’s unique specifications. For assistance or inquiries, our expert support team is ready to guide you at every step.

    Optional Accessories Installation Guides

    Enhance your Brummstadt head unit with these premium accessories. Each accessory is designed for easy DIY installation.

    External Microphone (Your Passengers Will Thank You)
    Game changer alert: Ever had someone say "Sorry, can't hear you!" on calls? Your built-in mic is doing its best, but it's fighting road noise. This external mic with noise filtering makes you sound crystal clear - even at highway speeds!

    Dead easy setup (honestly, 2 minutes):

    1. Connect to head unit: Find the 3.5mm MIC port in your wiring harness (it's with the RCA connectors). Just plug in the mic's 3.5mm connector until it clicks
    2. Pick your spot: Most people love the sun visor (clips on solid), but A-pillar or above the mirror work great too. The 3-meter coiled cable reaches anywhere
    3. Clip it on: The rotatable clip grips tight - sun visor, A-pillar trim, wherever works for you. About 30cm from your mouth is perfect
    4. Quick test: Call a mate and ask "How do I sound?" Prepare for compliments! Works brilliantly with Siri, Google Assistant, and hands-free calls

    Pro tip: Mic too quiet? Head to Settings → Sound → Microphone Gain. Start at 50% (perfect for most cars). Noisy diesel? Try 70%. The difference is amazing!

    🔊 Voice Quality Tip: After installation, fine-tune your microphone sensitivity in the head unit's audio settings. Test it out by calling your wife, husband, kids, friends, or even having a philosophical chat with the heavens above! Try voice commands with Siri, Google Assistant, or your preferred voice assistant to ensure crystal-clear audio. If they can't hear you properly, simply adjust the mic gain in settings until you sound like a professional podcast host!
    Rear View Camera Installation
    Compatibility: Rear camera alone works with all models (2/32GB and up). For front + rear camera combo, you need 4/64GB or higher.

    For Brummstadt Cameras (Plug & Play):

    1. Mount camera above license plate using provided bracket
    2. Run the camera cable through rubber boot between car body and trunk/door
    3. Route cable under trim panels to head unit location
    4. Connect yellow RCA plug to CAM-IN on head unit
    5. Connect red power wire to reverse light positive (this serves as the power trigger that tells the head unit to automatically switch to camera view when you shift to reverse)
    6. Connect black wire to chassis ground
    7. In Factory Settings → Backcar Settings, set to "Aftermarket Camera"

    Note: In most cases, connecting the red wire to the reverse light is necessary for automatic camera switching. However, in modern vehicles with CANBUS, this may not be required as the CANBUS module already controls screen switching (even if your car didn't come with a factory camera, the switching software is often pre-installed!))

    Camera will automatically activate when reverse gear is selected.

    DAB+ Digital Radio Module

    Installation Process:

    1. Connect USB module: Connect the DAB+ receiver to the USB 6-pin port on the back of the head unit (not the 4-pin port)
    2. Mount antenna:
      • Clean windscreen area (top corner recommended)
      • Stick the film antenna to the glass
      • Route cable along windscreen edge under trim
    3. Connect antenna to module: SMB connector clicks into place
    4. Activate in head unit: Open DAB+ app and scan for stations
    5. Ground for better signal: Connect the DAB+ module to bare metal in your vehicle - the car's metal body serves as grounding for stronger signal reception
    6. Position for best reception: Antenna works best with clear sky view
    7. Download app: Download a DAB+ app from the Google Play Store to start streaming digital radio
    ⚠️ Important: DAB+ coverage varies significantly by location. Check coverage maps for your area before purchasing to ensure you can receive digital radio signals.
    TPMS (Tyre Pressure Monitoring System)
    Choice of Systems: We offer both External (valve cap) and Internal (inside tyre) TPMS sensors. External is easier to install, Internal is more accurate and secure.

    External TPMS Installation (Valve Cap Type):

    1. Install sensors:
      • Remove existing valve caps
      • Screw on TPMS sensor caps (hand-tight only)
      • Note each sensor's ID number for position mapping
      • No tyre removal required - 5 minute installation!
    2. Connect USB receiver: Plug into available USB port on head unit
    3. Configure in app: Download and open one of these recommended apps:
      • TPMS by Vietmap: Simple interface, good for basic monitoring
      • USB TPMS: Advanced features with logging
      • Tyre Pressure Monitor: Clean UI with customizable alerts
    4. Map sensors: Assign each sensor ID to correct wheel position (FL, FR, RL, RR)
    5. Set alerts: Configure pressure (typically 32-35 PSI) and temperature warnings

    Internal TPMS Installation (Professional):

    1. Tyre removal required:
      • Remove wheels from vehicle
      • Dismount tyres from rims
      • Install internal TPMS sensors on valve stems
      • Remount and balance tyres
      • Professional installation recommended ($50-100 typical cost)
    2. Connect USB receiver: Same as external - plug into USB port
    3. App configuration: Same apps work for both internal and external sensors
    4. Advantages: More accurate readings, theft-proof, no risk of damage at car wash

    After Installation: Drive for 5-10 minutes to activate sensors. You'll see real-time pressure, temperature, and leak alerts directly on your head unit screen!

    Front and Rear Camera Combo (Live View)
    ⚠️ Requires 4GB/64GB or Higher: Front camera LIVE VIEWING while driving requires 4GB RAM models. The dual camera live view system is NOT compatible with 2/32GB entry models. (Note: Dashcam recording is different and works on all models)

    Dual Camera Installation:

    1. Front Camera:
      • Mount behind rearview mirror area
      • Connect to dedicated front camera input on head unit
      • Route cable along windscreen edge and A-pillar
    2. Rear Camera:
      • Mount above license plate
      • Connect yellow RCA to rear CAM-IN
      • Connect red wire to reverse light for auto-switching
    3. Configure in Settings:
      • Set both cameras in Factory Settings
      • Enable split-screen view option
      • Configure switching behavior

    Benefits: View both cameras simultaneously, switch between them while driving, perfect for towing or tight parking.

    Dashcam (Front Recording)
    ✅ Compatible with ALL models: Dashcam recording works perfectly on all models including 2/32GB. Records to SD card for incident protection.

    Installation Process:

    1. Mount the camera: Position behind rearview mirror for best view
      • Clean windscreen thoroughly
      • Attach using provided 3M adhesive mount
      • Ensure camera has clear view of road
    2. Connect power: Plug USB cable into head unit's USB port (any available port)
    3. Route cable: Tuck cable along windscreen edge and A-pillar trim to hide it
    4. Configure recording:
      • Open dashcam app on head unit
      • Set video quality (1080p recommended)
      • Enable loop recording (overwrites old footage)
      • Set G-sensor sensitivity for incident detection
    5. Storage: Records to the unit's internal storage (choose 4GB/64GB+ for longer recordings)

    Features: Continuous recording, automatic incident saving, parking surveillance mode when hardwired to constant power.

    RAM & Storage Options - Which to Choose?

    Quick heads up: The 2/32GB, 4/64GB or 8/128GB refers to the unit's built-in storage (like your phone's memory). This is permanent internal storage that can't be upgraded later.

    Which option suits you best?

    2GB RAM / 32GB Storage (Entry Level):
    • Basic CarPlay/Android Auto use only
    • Warning: May experience app refreshes or stuttering when multitasking
    • OK if you only use one app at a time
    • No 4G/SIM support at this level
    4GB RAM / 64GB Storage (Recommended):
    • Double the power - smooth multitasking
    • Run maps and music together without stutter
    • Includes 4G LTE & SIM card support
    • Room for apps and offline content
    • This is what most customers choose
    8GB RAM / 128GB Storage (Premium):
    • Power users and businesses
    • Run many apps simultaneously
    • Best for dashcam recording
    • Massive storage for offline maps
    • Future-proof choice

    💡 Pro Tip: The 2/32GB is really just an entry option. For proper multitasking without frustration, 4/64GB is the sweet spot!

    💡 Installation Tip: Most accessories connect directly with proper plugs. The rear camera may require connecting to your reverse light for automatic switching (basic wiring knowledge helpful). We include all necessary connectors and clear instructions.

    The Jeep Grand Cherokee has consistently embodied the spirit of adventurous versatility, rugged capability, and refined comfort since its debut, achieving enormous popularity and respect in different international markets. This globally recognized SUV, premiering in 1993, holds a special position among fans and automotive historians, thanks to its distinctively American styling, commitment to capability, and continual evolution through thoughtful generations. Exploring the broader model heritage helps deepen appreciation for the 1999-2005 Grand Cherokee and illustrates how purposeful design and practical enhancements continually refined the popular SUV.

    Historical Journey of the Jeep Grand Cherokee:

    First Generation — ZJ (1993–1998)

    Launched with great anticipation in 1993, the first-generation Grand Cherokee ZJ established Jeep’s firm presence within the mid-sized luxury SUV market. Internationally admired for its balance of sophisticated convenience features, robust off-road abilities, and refined cabin comfort, the ZJ was highly appreciated worldwide for off-road ready Quadra-Trac four-wheel drive system and powerful V8 options—especially in North America, Europe, and Australia. Luxury trim lines like the Orvis Edition and Limited versions elevated the ZJ's image from rugged SUV to a capable yet premium family vehicle, breathing fresh air in the expanding SUV segment.

    Second Generation — WJ (1999–2005)

    The thoughtfully revised Jeep Grand Cherokee WJ arrived in showrooms in 1999 as an innovative and refined evolution of the first-generation model, establishing itself as a benchmark in the mid-size SUV category. Longer, wider, and improved in virtually all areas from the ZJ, the WJ carried forth Jeep’s core strengths: genuine off-road capability, luxurious interior comfort, and potent powertrain options. The WJ captured global attention with its refined, quieter ride, improved suspension geometry, more precise steering, and roomier, elegantly designed cabin.

    Moreover, the Grand Cherokee WJ included noteworthy advancements in drivetrain technology, especially with Quadradrive—the sophisticated all-wheel-drive system offering enhanced traction and torque distribution even in challenging terrains. The robust range of engines—including the respected 4.7-liter V8 and much-lauded 4.0-liter inline-six—provided significant power, torque, and towing capabilities, impressing drivers in varied regions from North America to Europe and out to markets such as Australia and South America. The Overland trim introduced in 2002 delivered unparalleled luxury elements—combining upscale interior finishes, enhanced ride quality, and premium styling details—for global markets that increasingly favored SUVs as prestigious family vehicles rather than purely functional machines.

    Third Generation — WK (2005–2010)

    Building upon the global success and refinement of the WJ series, the Grand Cherokee WK brought further modernization to the lineup in 2005. Updated exterior aesthetics, advanced chassis technology, powerful engine selections—including notable additions like the renowned HEMI V8—and refined interior appointments helped this model strengthen its luxurious yet capable reputation worldwide. Many former WJ owners naturally progressed into the WK series as loyal supporters of the sophisticated refinement, reliability, capability, and Jeep heritage.

    Integrating a Premium Infotainment Experience—Brummstadt Enhancement:

    Owners of the 1999-2005 Grand Cherokee WJ increasingly seek infotainment updates to align their beloved vehicle with contemporary connective technologies and functionality. Among recommended options, Brummstadt offers an advanced head unit tailored specifically to suit this Grand Cherokee model series, directly replacing original units with a device seamlessly fitting dashboard space and aesthetic.

    With wired and wireless integration for Apple CarPlay and Android Auto, owners gain easy access to familiar smartphone interfaces and compatible apps—including Apple Maps, Google Maps, and WAZE—streamlined naturally into the vehicle's existing setup. Imagine an evening spent dining with family or a relaxing afternoon visiting a favorite café. Before departure, destination maps preset via smartphone navigation automatically transfer to the head unit through wireless CarPlay or Android Auto integration, allowing intuitive, frustration-free transitions from casual evenings to friend's gatherings or home relaxation, even when navigating unknown streets.

    Another noteworthy element includes the availability of 1080p HD cameras, designed to operate seamlessly with this upgrade—front and rear cameras offering clear imagery, recording capability, and significantly enhancing overall driving confidence, maneuverability, and safety. For families or friends traveling together, entertainment further diversifies as passengers can connect gaming joysticks through USB ports for engaging multiplayer games directly displayed on the new head unit, cultivating memorable on-road experiences beyond mere transportation.

    Smart voice assistant integration introduces another modern convenience: The head unit complements everyday routines by connecting effortlessly with voice assistants like Siri or Google Assistant. Drivers can efficiently manage navigation, answer calls, or choose music safely while driving. Importantly, these assistants synchronize effortlessly with smart home products, allowing scenarios such as, "Hey Siri, switch on the porch lights," enhancing daily convenience by seamlessly linking domestic and driving experiences into one integrated lifestyle.

    Advantages of Jeep Grand Cherokee WJ (1999–2005) and Value of Thoughtful Upgrades:

    The Grand Cherokee WJ represents a distinctive model respected globally for its rugged Jeep persona combined comfortably with premium automotive refinement. Drivers appreciate elegant yet robust styling, reliability under demanding off-road conditions, powerful engine options, generous interior comfort, and commendable driving dynamics. Its ability to balance daily urban functionality with adventurous capability renders this SUV particularly cherished worldwide—from bustling city streets to rural backcountry roads.

    Incorporating thoughtful contemporary upgrades—like Brummstadt's advanced infotainment solution—provides valuable modernization, minimizing compromise between a classic vehicle heritage and contemporary comfort and convenience expectations. This translates directly into joy and driver satisfaction, empowering peaceful guidance for navigation, improved entertainment options, comprehensive safety enhancements enabled by camera recording, and seamless smart connectivity within a carefully designed package integrated smoothly into the Grand Cherokee's modern-classic interior.

    The Jeep Grand Cherokee WJ's legacy endures as a tangible representation of the automotive excellence customers globally have appreciated for decades. Its true strength lies in rare versatility, robust construction, and premium, thoughtfully refined characteristics—a vehicle shaped by purposeful evolution and continual enhancement, warmly loved and consistently respected.

    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.

    Yes! Most vehicles work instantly. If not, use the steering wheel learning app: tap the steering wheel icon, press each button on your wheel, and assign functions. For newer vehicles with CANbus, we provide CANbus modules for automatic setup. Some vehicles may need the Key1/Key2 wires connected (usually included in our harness). If you're having trouble, let us know your exact vehicle model and we'll provide specific instructions.

    We offer a 30-day return policy. If it doesn't fit or there's a compatibility issue, we'll work with you to resolve it. If you change your mind, a 20% restocking fee applies. Our team verifies compatibility before shipping to minimize issues. We provide installation support 7 days a week to help resolve any problems. With our 3-year warranty and Australian-based support, you can purchase with confidence. Full details in our Refund Policy.
