How to Install 11.4 Inch Rear Entertainment Screens on a Defender L663 (2020–2026)
These 11.4 inch rear entertainment screens for the Defender L663 address that gap precisely. Running on Android OS with 4GB RAM and 64GB of onboard storage, each screen is a fully independent smart display — capable of running apps, streaming content over built-in Wi-Fi or 4G, and mirroring your phone via screen mirroring. The 1080p HD display delivers crisp, vivid images even in bright daylight, and the lossless Bluetooth module means passengers can connect their own headphones without disturbing those in the front.
Critically, these screens are engineered specifically for the Defender L663. They come with a 1:1 replica of the original factory mounting bracket, meaning they slot into the existing headrest mounts without modification, drilling, or cutting. The finish and form factor are designed to match the Defender's interior aesthetic — this is an upgrade that looks factory-fitted from day one. This guide walks you through the complete installation process, from unboxing to first power-on.

Why this upgrade transforms the Defender L663 interior
The Defender's cabin has evolved enormously since the L663 arrived in 2020. The Pivi Pro infotainment system serves the driver and front passenger well, but rear occupants — particularly on longer motorway runs or school runs — are left relying on their own devices, often hunched over phones or tablets in a less-than-ideal viewing position. A dedicated headrest screen changes that dynamic entirely, elevating what is already a premium space into something that feels genuinely comparable to high-end executive transport.
At 11.4 inches with a 1080p HD panel, these screens are substantially larger than what you'd find in most factory-fitted rear entertainment options on other vehicles. Content is sharp and vibrant, and the display size is generous enough to be genuinely comfortable to watch rather than merely functional. Whether rear passengers are watching a downloaded film, streaming via the screen's own 4G connection, or mirroring their phone screen, the experience is a significant upgrade over anything the standard Defender offers.
The built-in Android OS is what sets this product apart from simpler passive display systems. Passengers aren't limited to a single input or a physical media library — they have access to the full Google Play ecosystem. Streaming apps, navigation, games, and productivity tools are all available. The 4GB of RAM ensures performance is smooth, and 64GB of onboard storage provides ample space for downloaded content on long journeys without connectivity.
From a presentation standpoint, the factory-matched bracket means the finished result is indistinguishable from an OEM fitment. There are no exposed cables, no afterthought fixing methods, and no visual compromise to the Defender's interior. For an owner who has invested in a vehicle at this price point, that level of finish matters.

Before you start
Important: Disconnect the vehicle from any mains charging source before beginning. If you are routing power cables behind panels or under seat upholstery, ensure the ignition is off and, if connecting to a switched live feed, verify the wire with a multimeter before making any permanent connections. Take care with trim removal tools around the Defender's leather or textile upholstery — scratches to the headliner or seat backs are difficult to reverse.
- Park the Defender on a flat, well-lit surface and switch off the ignition. Leave the vehicle for 10–15 minutes if the engine has been running.
- Lay a microfibre cloth over the rear seat backs and seat base to protect the upholstery while working.
- Remove both rear headrests from the seats and set them aside on a clean surface.
- Unbox the screens and brackets, and verify all components listed above are present before proceeding.
- Download any required apps or updates via Wi-Fi before fitting if you want the screens ready to use immediately after installation.
- Familiarise yourself with the wiring harness and identify the power input connector on each screen unit.
Step-by-step installation
1Remove the original rear headrests
Press the headrest release button (located on the seat back collar around each headrest post) and pull each headrest directly upward. On some Defender L663 seat variants there is a locking tab — press this inward while pulling upward. Set the original headrests aside; you will not need them once the entertainment screen units are fitted.
2Inspect and prepare the headrest guide collars
With the headrests removed, inspect the guide collars in the seat back — these are the plastic tubes the headrest posts slide into. Ensure they are clean and undamaged. If there is any debris inside the collars, clear it out with a soft cloth before inserting the new mounting posts. The factory-replica brackets supplied with these screens are designed to use the same collar sizing as the original Defender headrests.

3Attach the mounting brackets to the screen units
If your screen units arrived with the brackets unattached, now is the time to fit them. The bracket connects to the rear of each screen via the provided screws — use the Phillips PH2 screwdriver and tighten firmly but without over-torquing. Each bracket has two posts that mirror the spacing of the original headrest posts exactly, ensuring a flush, rattle-free fit in the seat collars.
4Route the power and signal cables down through the seat back
Before inserting the screen units into the seat, thread the power harness cable down through the seat back. On the Defender L663, there is typically a gap between the seat back foam and the outer upholstery panel near the base that allows cable routing. Feed the connector end of the harness downward so it exits at the base of the seat, where it can be connected to a 12V accessory feed or the vehicle's fuse box. Use a trim removal tool to carefully lift the base of the rear seat back panel if needed to guide the cable cleanly.
5Insert the screen mounting posts into the seat guide collars
With the cable routed, hold the screen unit above the seat back and align the two mounting posts with the guide collars. Lower the unit firmly and steadily until it seats fully. You should feel it lock or stop positively — the posts have the same retention detents as the original headrests, so the screen will click into place at the correct height. Check that the screen is level and centred in the seat back before moving on.

6Connect the power harness to a 12V feed
The screens require a constant or switched 12V supply. The easiest approach for most installers is to connect to the rear fuse box, using an add-a-fuse adapter on a switched ignition circuit — this means the screens power on and off with the vehicle. Alternatively, connect to the vehicle's existing rear USB or 12V accessory socket if the harness adapter allows. Use a multimeter to confirm polarity before making the final connection. Secure all cables with zip ties to prevent movement or rattling.
7Pair the Bluetooth module with the vehicle head unit or headphones
Power the vehicle on and allow the screen to boot into Android OS. Navigate to the Bluetooth settings on each screen and put them into pairing mode. To connect to the original Defender Pivi Pro head unit, ensure Bluetooth is enabled on the infotainment system and select the screen from the available device list. Alternatively, pair each screen with a set of Bluetooth headphones for independent private listening. The lossless Bluetooth module supports high-quality audio codecs for the best sound experience.
8Connect to Wi-Fi or insert a SIM card for 4G
Access the Wi-Fi settings in Android and connect the screens to your home or mobile hotspot network to download apps and updates. If you plan to use the built-in 4G for standalone connectivity, insert a compatible nano-SIM into the SIM slot on each unit (check the product documentation for the slot location, typically accessible from the rear or base of the unit). The screens support global network frequencies and will connect automatically once a valid SIM is inserted.

9Enable phone screen mirroring
Both Android and iOS devices can be mirrored to these screens. For Android phones, use the Cast or Screen Mirror function from the quick settings panel and select the rear screen from the list of available displays. For iOS devices, use the AirPlay or third-party mirroring app as supported by your device. This allows rear passengers to share content, maps, or media directly from their own phones to the large 11.4-inch display.
10Tidy all cables and refit any displaced trim
With both screens operational, do a final check of all cable routing. Secure any loose sections with zip ties or hook-and-loop cable ties. Ensure no cables are pinched under seat rails or caught in moving parts. Refit any trim panels that were lifted during installation and press them firmly into their clips. Run the seat back and forth through its adjustment range (if applicable) to confirm nothing catches or binds.
11Test all functions before closing out
With the installation complete, power the vehicle on and run through each screen's key functions: check the display brightness and resolution, confirm Bluetooth audio, test Wi-Fi or 4G connectivity, verify screen mirroring from a phone, and confirm the IR remote controls are working with both units. Play a piece of video content to confirm the 1080p display is functioning as expected. Only sign off on the installation once all features are confirmed working.
Common mistakes to avoid
- Connecting to an unswitched live: Wiring the screens to a permanent 12V feed means they will continue to draw power with the ignition off, potentially draining the battery overnight. Always use a switched ignition circuit.
- Not routing cables before inserting the screen: Attempting to thread the power cable after the screen is already seated in the guide collars is difficult and risks damaging the seat upholstery. Always route cables first.
- Forcing the mounting posts: If the posts don't drop smoothly into the guide collars, check for debris or misalignment rather than forcing the unit — forcing can crack the collar housing.
- Skipping the boot update: Android devices benefit from running the latest OS version and app updates. Connecting to Wi-Fi and updating on first boot ensures the best performance and access to all features.
- Ignoring cable management: Loose cables behind the rear seat area can rattle over rough terrain — something the Defender will inevitably encounter. Take time to secure every cable run properly.
- Pairing both screens to the same Bluetooth headphone set: Each screen has its own independent Bluetooth module. Pair headphones to the specific screen the passenger is using, not both simultaneously.

Care and maintenance
- Clean the display surface with a soft, dry microfibre cloth. Avoid abrasive cloths, screen wipes containing alcohol, or excessive moisture near the screen edges.
- Keep the Android OS and installed apps updated regularly via the built-in settings menu to maintain performance and security.
- If using a SIM card for 4G, ensure it remains correctly seated — vibration from off-road use can occasionally dislodge nano-SIMs in some unit variants.
- Periodically check the cable connections at the fuse box end to ensure the add-a-fuse adapter remains secure, particularly after extended off-road use.
- If the screen is unused for an extended period (e.g. vehicle in storage), consider disconnecting the power feed at the fuse box to prevent any parasitic draw.
- Protect the screens from direct, prolonged sunlight exposure when the vehicle is parked in hot conditions — use a sunshade on the rear window if needed.
