OMG, it's so easy and so simple... I was talking w/ albert about the setup process, splicing into wires and grounding them. I open up my box and well, there were no power wires so I'm like "wtf, am I missing parts?" Turns out, the entire signal... powerfeed, audio source, is all sent through the single wire that plugs into our stock HU, and after that, plug in your antenna, and after that, activate it and BAM, it works. Just that easy. No mess. No tapping into wires. 100% plug and play! Just thought I'd share my excitement, and get all those stragglers who haven't gotten Sirius yet to get it. Get it now!
