Hi, I'm trying to install a Sony Xav-68bt headunit into my Vx commodore. I'm new to car electrics and have a few questions. First, I have both the Aerpro VX commodore and Sony specific AV connectors. I get that this should be a simple plug and play install, but I'm unsure if the amp trigger wire has to be connected to anything (as I still have the factory amp). Second, does anyone know theeasiest way to connect the reverse in wire to the Sony harness? My last question, has anyone installed a Axxess aswc-1 in their car, there is no information on their website. Any help would be greatly appreciated, thanks.
