From what I've read, the cordless ones are in a different (worse) league. Just what I've read...if you agree, then maybe best to have a stereo shop install a line for the V1. It really isn't that hard, but experience helps to determine what pops out and what unscrews. I figure 2 hours max for that, maybe at $40/hour? I would think that you could pull a lead off the fuse compartment, which is closer to the pillar, but I liked having the extra room to work behind the stereo, and I already knew exactly which wire to splice into.
