Pioneer AVIC8000NEX deck no Audio

[tenkies]

I have a 2012 Sport with Bose no Navi. I tried installing my Pioneer AVIC8000NEX deck and got it to power, no problem but I'm getting 0 audio through the speakers. Tried getting sound via the HD radio and also from my phone which the head unit found and was streaming via BT. I tried swapping the RCA's on the harness to the front and rear outputs on the head unit and still nothing. Could it be a bad head unit? or did I wire something bad?

using the following:
Metra 70-7553 Harness
Scosche NAA2B 2007 - Up Nissan Versa Antenna Adapter
Axxess ASWC-1

I thought it might be issues with the ASWC so I unplugged the harness from the box and still no joy. Any advice is appreciated. Thanks.
