on our 2001 e 320 the navigation voice sometimes gets so quiet its almost impossible to hear. it goes back to normal then to quiet. we had a 200 s430 which did the same. does anyone know if its a certain part which is replaceable or is it a seperate speaker for it? in settings on the command system we set the volume to high, but its not enough to here it. it is so intermitant that you never know when it gets quieter.
thanks
