Thanks for the replies. It does have a phone and teleaid however no faults are showing. I pulled the comand unit and checked for the 4 light lock pulse. looked good and strong. Next I checked the 4 light pulse at the end of the fiber before the first D2B component. looked good. Then checked the light pulse after the first component. ok again. the next D2B component was the amp. I heard it click four times but no light exiting the amp fiber. I strongly suspect the amp is dead. I have reset the D2B ring through the head unit diagnostic menu. I ordered a nw amp from ebay. Ill let you guys know how it turns out.

Thanks
