Rolls-Royce: sound problems and electronic faults in the multimedia system

You own a Rolls-Royce and you suddenly come across a sound problem ?
No sound comes out of the loudspeakers, whether for music, alerts, parking assistance or the multimedia system?

This type of breakdown is unfortunately well known on certain Rolls-Royce models and is most often the result of an electronic malfunction.

Frequent causes of breakdown

On many Rolls-Royce models, the amplifier and a number of multimedia system components (TV receiver, radio, CD loader, video module, etc.) are also included.
are installed under the rear seats.

A recurring breakdown is linked to a water ingress, which could damage one or more of these electronic components.

Fibre optic communication (MOST loop)

On several top-of-the-range models, communication between the various multimedia modules is via a fibre optics (MOST loop).

Each module has a fibre input and output, and all the modules are connected to each other. in series.
As a result, if a single module fails, the flow of information is interrupted, resulting in a general multimedia system failure.

Specialist Rolls-Royce electronic diagnostics

From an electronic point of view, the Rolls-Royce multimedia system is very similar to that of BMW vehicles.

We have all the necessary diagnostic interfaces required, a fibre optic tester, and a ICOM B module,
allowing a precise diagnosis of the fibre optic loop and rapid identification of the faulty module.
