Hello, I am new to this forum and new to these Pioneer AVIC Z2 units. I found a deal on a used AVIC Z2 thats been updated to a Z3 and I want to install this unit in my 2006 Dodge Ram that has factory navigation and infinity sound. Does anyone know if this will hook up and if so will I need any special instructions and/or wiring harnesses? Also I want to install Sirius satelite. What all will I need to make this unit work for me? Thanks in advance, Andy
