Hi all.

I need help!

I have error message showing on PCM 2.1 ERROR CD CHANGER, NAVAGATION. When going into the diagnostic tool on PCM it shows no input from CD CHANGER, NAVAGAITION & AMPLIFIER. I have swapped over the PCM so i know its not that Swapped over AMP also.

I HAVE NO SOUND!!

CAR HAS BOSE AMP!

Optic light.
Now I'm not sure if I'm missing something here;

Light goes from PCM,
Into block connector before amp.
then into AMP (BUT NOT OUT OF AMP).
Light going into CD Changer not out
Light going into NAV drive not out.

I have brought the car with this fault and not sure on the history but could anyone shead any light on this.

AM I GOING MAD HERE?
