M-Series: Steering Wheel Control Not Working in Toyota LandCruiser 200 Series (2016–2021 GXL, Altitude)

If you've upgraded your Toyota LandCruiser 200 Series (2016–2021 GXL, Altitude) with a VHEDIA Head Unit but the steering wheel controls aren't working, you're in the right place. This guide covers what might be going on and how to fix it.

While most vehicles use CANBUS to communicate with steering wheel controls, some Toyota LandCruiser models—especially in the GXL range—may require a different setup or a specific harness to get the buttons working properly with your VHEDIA head unit.

We'll help evaluate your vehicle’s setup and determine if a specific harness is needed for your steering wheel controls to function correctly. In most cases, once we confirm your vehicle’s configuration, we’ll send out the correct harness if required.

2.  Install the New Harness (If Provided)

• Disconnect the wire labelled "AD" → Then connect it to the plug labelled "AD2"
