Hi everyone, I’m new to AVIC 411 but not new to car audio and video installation and this one defies explanation. Bottom line up front: I get no sound from AM/FM and Sirius! I get perfect sound from iPod, DVD/ CD, SD, phone, even thru Bluetooth. The details: I installed an AVIC Z120 BT in a 2005 Chevy Avalanche. The Avy has On star and has Bose. This is the second aftermarket HU installation for this truck. I installed it using a Metra GMOS-04 and “yep†the blue wire w/ white stripe from the HU is connected to the blue wire w/ white stripe on the GMOS-04. The wire has voltage when the HU is on, even when the radio or Sirius is playing. I used a test light and I can tell because the AMP powering my rear subs is powered up. Help!

UPDATE! I now have no sound from the iPod too. I did the parking brake bypass and now only have sound from DVD/CD and phone. anyone,????
