I am trying to hook up the z110bt in a 2010 Avalon. The wiring harness is Scosche TA07SR. http://www.scosche.com/products/sfID1/151/sfID2/159/productID/1447 The harness has red, orange and yellow wires which I have connected to the power plug of the Z110bt. But it has RCA cables to connect to the LF, LR, RF, and RR channel inputs. Where do I connect these RCA plugs on the Z110bt. Also, does anyone know where the VSS and the reverse light wires are in the Avalon?

Will the Z110BT interrupt audio from the radio or XM for verbal navigation directions? Or, can you program the unit to have the directions over the radio?
