Head Unit E‑Manual
Clear information for shopping, delivery and product support.
Use this guide as a preparation checklist, not as a substitute for the vehicle wiring information.
Connector locations and procedures vary. Stop if the product, fascia or wiring does not match the vehicle.
Before removal
Save important radio settings where required, confirm security codes, place the vehicle in a safe position and follow the correct battery-disconnection procedure.
Remove trim carefully
Use non-marking tools and keep screws organised. Photograph original connectors before disconnecting them, especially when multiple similar plugs are present.
Connect power and speakers
Use the supplied harness without cutting factory wiring where possible. Never connect an unknown wire based only on colour; verify its function.
Connect CANBUS and controls
Install the correct interface and select the supported vehicle profile where required. Test every steering-wheel button before final assembly.
Connect cameras and accessories
Confirm video signal type, trigger wire, camera power voltage and grounding. Route microphone, USB and antenna cables away from sharp edges and moving parts.
Set up CarPlay and Android Auto
Pair Bluetooth and Wi‑Fi according to the product application. For a wired connection, use a suitable data cable and the correct USB port.
Complete the functional test
Test all audio sources, calls, microphone, maps, controls, camera, illumination, sleep and restart behaviour. Check for warning messages or battery drain.
Final assembly
Secure cables, avoid pressure behind the screen and refit the trim evenly. Keep the original parts and record the selected settings for future support.
