Vehicle: 2020 Land Rover Discovery HSE Luxury

Hi Land Rover community,

I'm having major issues with the InControl Touch Pro system in my 2020 Land Rover Discovery HSE Luxury. The touchscreen frequently freezes, becomes unresponsive, and sometimes just goes completely black for several minutes before restarting itself. It's incredibly frustrating, especially when I'm relying on navigation or trying to adjust climate controls.

I've tried restarting the car, and sometimes it helps temporarily, but the problem always comes back. Is this a known software bug that needs an update, or could it be a hardware issue with the screen or a control module? I'm not getting any specific error messages on the main dash, just the screen acting up.

Any advice on what to check or if there's a specific fix for this would be greatly appreciated. Thanks!

ClearTheCode admin answer:

Infotainment system glitches are unfortunately not uncommon in modern vehicles, and Land Rover's InControl systems can sometimes experience these issues. The symptoms you describe – freezing, unresponsiveness, and black screens – point to either a software malfunction or a hardware fault within the system's components.

Here's a breakdown of potential causes and steps:

  1. Software Glitch/Update:
    • The most common cause is a software bug. Ensure your InControl Touch Pro system has the latest software update. Dealers often perform these during routine service, but you can also check for over-the-air updates if your vehicle supports it, or inquire with your dealership.
    • A 'hard reset' of the infotainment system can sometimes clear temporary glitches. This usually involves holding down a specific button combination (e.g., the power button and volume down button simultaneously for 10-20 seconds) until the screen restarts. Consult your owner's manual for the exact procedure for your 2020 Discovery.
  2. Module Communication Issues:
    • The infotainment system relies on several control modules communicating via the vehicle's CAN bus network. If there's a fault in one of these modules (e.g., the head unit, telematics control unit, or a gateway module) or a wiring issue, it can cause intermittent operation.
    • Diagnostic Trouble Codes (DTCs) related to communication errors (U-codes like U0140, U0155, U0231) might be stored in the system, even if they don't trigger a dashboard warning light.
  3. Hardware Failure:
    • Head Unit: The main control unit for the infotainment system can fail internally.
    • Screen Itself: Less common, but the display panel or its internal controller can develop faults.
    • Wiring/Connectors: Loose or corroded connections to the head unit or screen can cause intermittent power or data loss.

When to See a Shop: If a software update or a hard reset doesn't resolve the issue, or if the problem persists and becomes more frequent, it's crucial to have your Land Rover Discovery inspected by a dealership or a specialized automotive electronics shop. They have the proprietary diagnostic tools to read specific module fault codes, test component functionality, and perform necessary software re-flashes or hardware replacements. Ignoring the issue could lead to more significant system failures down the line.
