Replacing the Component

Before continuing with fault-tracing, the following must be checked:

All tests for the relevant symptom must have been carried out
No component, connector or wiring faults etc. should have been detected.

Try a new head unit/audio module.

CAUTION: New head unit/audio control modules are supplied without software. The head unit/audio control module must be programmed after it has been replaced.

Other information:

For information about programming and accessing or replacing the main unit and/or audio control module, see Radio/Carphone, Replacing (For -2004) and Audio Unit, Replacing (For 2005-).
