Hey Brian,
Any user reviews of the nuvi, or are you so engrossed in camcorders at the moment that it's still in the box..?
Jason, a lot of the modern camcorders have dropped features like mic inputs and video inputs. I bought the DV Canon that I had before the HDV Sony I've got now just because it had the ability to record from AV inputs (this was before there was a TivoToGo solution for the Mac). The HDV Sony I have can't record from AV inputs (AFAIK) but it does have a mic input. It's the consumer level camera, so it's 1/8in plug, not XLR, but that's OK.
