Hey , why don't you give NAVTV a try? Its a US based company, and it is not NAVI-TECH. Its been more than a week, and I am happy with the performance and reliability thus far. But I would definitely pay for a pro installer to put it in. Instructions are provided on connections, and it just depends on the quality work of the installer. Go for it... you won't regret it.David, please let us know about your system, the install, costs, picture quality, resolution, etc. I am still interested in finding a good high quality system that works. I also feel a good system is a good investment for our cars. Thank you.
