    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 Kia Optima, globally recognized and appreciated across various markets under different nameplates including Kia K5 in its Korean home market, stands proud within Kia’s automotive legacy as a practical, refined, and increasingly sophisticated midsize sedan. Since its initial launch, the Optima has steadily evolved into a distinctly contemporary car, admired for its remarkable value, thoughtful luxury, impressive technological advancement, and sturdy performance capabilities. Tracing back its lineage provides valuable insight into how the Kia Optima GT (2015-2020) has reached its prominent status.

    Historical Progression of the Kia Optima:

    First Generation - Kia Optima (MS) 2000–2005:
    Introduced first to the North American market in 2000, the original Optima was built as an approachable family sedan rooted deeply in practicality. Known elsewhere by different names, including Kia Magentis in European and Canadian markets, the car appealed strongly to families and daily commuters due to solid reliability, efficient engines, affordable price tag, and straightforward comfort.

    Second Generation - Kia Optima (MG) 2005–2010:
    The second-generation vehicle signified substantial improvements in style, refinement, and overall mechanics. Recognized again as Magentis in some geographic regions, this iteration showcased important advancements in interior material quality, passenger roominess, and road manners. Kia's reputation for affordability became increasingly complemented by noticeable improvements in build quality, smoother driving dynamics, and refined engines—which set the stage firmly for increased recognition.

    Third Generation - Kia Optima (TF) 2010–2015:
    Representing Kia's ambitious inroads into the more competitive midsize segment, the third-generation Optima stood powerfully distinguished through breakthrough styling under renowned designer Peter Schreyer—instantly setting benchmarks in contemporary automotive design. Across global markets, the TF Optima introduced elevated refinement, increased interior ergonomics, quality infotainment and comfort features, positioning itself effectively against established competitors. Particularly in North America and Australia, robust engine options, including a turbocharged variant, and the availability of hybrid versions solidified Optima's reputation significantly among critics and drivers alike.

    Fourth Generation - Kia Optima (JF) 2015–2020, Including Optima GT:
    Launching the fourth generation marked another substantial leap forward for Kia’s midsize sedan line-up, amalgamating modern conveniences, sharper driving dynamics, elevated quality, and increased premium features. Introduced at global auto exhibitions and arriving throughout 2015-2016 in most regions, this generation further polished the vehicle’s refined aesthetics and aerodynamics—combining athletic curves, elegant sculpting, and modern lighting elements to create an imposing road presence without losing the practical and approachable appeal.

    Within the fourth generation came a specific embodiment of Kia's sporting ambition—the Kia Optima GT. Donned with sportier detailing, attractive alloy wheels, twin exhaust outlets, and subtle GT-specific embellishments inside and out, the Optima GT distinguished itself as a clear, dynamic step over standard models. Under the hood, the GT received a powerful 2.0-liter turbocharged engine, confidently delivering robust acceleration and impressive torque, matched thoughtfully with a refined yet sporty suspension system and enhanced steering responsiveness. With these attributes, the Kia Optima GT became an attractive option for drivers valuing both stirring performance and desirable comfort.

    Inside, spacious interiors materials, extensive leather trimming, and supportive seats ensured noticeable luxury. Technologically, this Optima generation significantly advanced Kia’s infotainment capabilities, initially featuring systems with Bluetooth connectivity, smartphone integration, and clear touchscreen interfaces. However, for drivers seeking enhanced interactive experiences, aftermarket integration became increasingly appealing.

    Enhancing Experience Through Technology Integration:

    Brummstadt's specialized premium head unit stands as one example specifically tailored for Kia Optima GT 2015-2020, effectively complementing the original vehicle architecture while elevating the interaction between vehicle and owner. Carefully designed to match Kia's refined interior aesthetics and dash dimensions, this advanced infotainment system offers extensive connectivity compatibility through both wired and wireless Apple CarPlay and Android Auto integration.

    Functionally, such integration makes commonly used navigation tools—like Google Maps, WAZE, or Apple Maps—directly accessible, thus simplifying and streamlining driving experiences. Visualize an enjoyable dinner with family, after which the driver conveniently selects a friend's address on their smartphone before leaving the restaurant. The navigation automatically interfaces via wireless Apple CarPlay or Android Auto on the larger head unit screen as soon as they re-enter the vehicle—no distractions, no complications, simply an effortless transition from dining conversation to continued companionship elsewhere, enhancing social connection and driver ease.

    Additionally, Brummstadt offers optional integration with discrete and reliable 1080p HD front and rear cameras, designed to augment visibility, promote preparedness during unpredictable traffic events, and record valuable visual footage. Entertaining possibilities expand beyond navigation or standard infotainment, as integrated USB ports accommodate state-of-the-art joysticks for engaging multiplayer gaming directly displayed on-screen—transforming routine commutes or family trips into interactive group activities.

    Moreover, comprehensive smart voice control integration with digital voice assistants (e.g., Siri or Google Assistant) supports effortless management of calls, messages, navigation directions, and multimedia selections. Furthermore, linking voice-controlled head units with smart-home technology features enables useful remote functions—such as remotely activating porch lights upon arriving, contributing purposefully towards modern convenience and safety routines.

    Benefits and Driving Satisfaction Derived from the Kia Optima GT:

    Over the decades, the Kia Optima has consistently risen to higher levels of appreciation globally. Whether known as Optima or K5, it cultivated respect through modern design incorporating genuinely luxurious touches, responsive performance, economically sound engine options, comprehensive safety features, and refined driving dynamics combined with real-world practicality.

    Specific attributes inherent to Optima GT particularly amplify driving appeal: athletic yet composed handling responses, comfortably firm suspension tuning, and confident turbocharged power delivery merging harmoniously with spacious and luxurious cabin environments. Premium aftermarket options, especially in carefully considered infotainment integrations provided by Brummstadt head units, serve as valuable technological additions, greatly refining vehicle interactions and introducing convenience features previously unconsidered.

    Through this union of capable yet composed automotive engineering with contemporary smart technology, the Kia Optima GT 2015-2020 models present themselves not merely as dependable transportation but as genuinely enjoyable and meaningful automotive companions. For drivers valuing genuine refinement, practical luxury, spirited dynamism, and meaningful technological integration, few vehicles genuinely deliver such carefully tailored balance.

    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.
