I took my car to an installer I have known for many many years. I used to have a show car back in the late 80's when car stero was just starting to get big, and all this guy does is design an install the massive car stero set-ups.

I bought my equipment elsewhere (so when I told you I paid just under $1600 bucks for the voice unit and head unit that was stand alone for those items less install) and had my installer put the stuff in. I did a bit more than just put the head unit in, if you go to the Topic "questions for you AVIC-N1 folks" that is the thread I started. You can read about what I did there. Cost to do the whole job for my sytem, and that included a speaker upgrade was $400 bucks, and I give him a $50 tip. Job took about 6 hours to do everything. If I just was doing the head unit and hooking up to the factory stuff he told me it would have taken him about and hour to an hour and a half.
