Land/Range Rover Infotainment System Fault diagnostics & fix (optical MOST Bus) L404 L405

In this video we take a look at fixing the problem with the Phone / Naviagation / Radio system on our Range Rover Sport L494. The problem was that these modules were greyed out on the touch screen and could not be accessed. As all these items are on the optical MOST bus ( Media Oriented Systems Transport ) it seemed to point to this being the problem. So in this video we show how to fault find the optical MOST bus looking at the signals to the Amplifier / DAB reciever / Instument Cluster / Touch Screen etc. This should be the same on many Jaguar models like the Jaguar XF For all your Land Rover / Range Rover Accessories
