Jaguar XJ (X351) 2010–2020 Android Head Unit Installation: Step-by-Step Guide

Installing a SMARTY Trend Android multimedia head unit in an executive Jaguar XJ / XJL (X351, 2010-2020) sedan allows you to fully modernize the outdated factory Bosch or Harman system. You get a modern 10.25-inch IPS/QLED touchscreen display, wireless Apple CarPlay, Android Auto, real-time navigation, and access to Google Play apps. At the same time, all factory functions-from the original OEM interface and climate control to the 360-degree camera system and Meridian / Bowers & Wilkins audio-are 100% preserved.

Step-by-Step Installation Guide

Step 1: Removing the Screen Trim and Climate Control Unit

Using a plastic trim tool, carefully pry off the decorative trim surrounding the factory screen. Once the clips are released, remove the screws securing the climate control unit and screen assembly.

Step 2: Removing the CD Drive and Cable Routing

Remove the climate control module and unscrew the two mounting screws of the lower CD host unit. Connect the main power harness and CAN line in series with the factory CD drive connector, then route the power and audio cables up to the main display cavity.

Step 3: Transferring the Original Screen Motherboard

To preserve full functionality of the factory Jaguar menu, air suspension settings, and climate controls, the original motherboard must be transferred from the factory screen into the supplied SMARTY Trend protective housing.

1. Disassembly: Disassemble the original display housing and carefully remove the main PCB board.
2. Connection: Attach the flexible ribbon cable from the new head unit to the factory board header.
3. Securing: Secure the motherboard inside the provided metal protection box.

Step 4: Testing and Reassembly

Connect the GPS/4G antennas, USB ports, and main wiring harnesses to the new 10.25-inch display. Reconnect the battery negative terminal and verify system performance before final dashboard reassembly:

• OEM Menu: Confirm smooth switching to OEM mode and check factory menu controls.
• Audio System: Verify sound output through the AUX channel to the Meridian audio setup.
• Cameras & Steering Controls: Engage reverse gear to verify parking camera displays and test steering wheel button responses.
