I'm installing a Pioneer F90BT in a 2003 G35 Coupe with the factory bose amp. I'm using the metra 70-7551 harness and I seem to have everything hooked up but there is NO audio. None whatsoever. The unit turns on, I can switch audio sources, see the nav, but nothing will play out of the speakers. Please any idea what's going on? Anybody?

you did connect the amp turn on wire (blue/white)correct?

its the wire that allows the AVIC to tell the Bose amps to turn on
