Hi Neil, Thanks for response. The problem with the volume seems to be intermittent. It is okay today - tomorrow?? Will see how it goes.
Where is the amplifier located? Please clarify what yo mean by "head unit". Thanks.
Have suddenly lost all volume from my GS300 [2005] audio system. Can rotate the volume knob any way but no volume scale/level shows [as would normally be the case].
The rest of the display seems normal - just no sound in any mode. Thoughts?
