Hello,
I want to add a navigation unit in the form of a head unit with a lcd fold out screen. I am interested in the Pioneer AVIC-N1. I have a few questions.

What mounting brackets will I need to hook up the unit?

Where does the power for the unit come from; do I have to use the cigarette adapter power?

If I want to use my stock stereo but just use the navi unit; am I able to hook up the RCA outputs to my stock stereo and use the amp and speakers there?

If I choose to use the stock stereo, is there anyway i can change the front tweeters and woofers without having to change the amplifier? What ohms is the amplifier rated at? Is there a crossover hidden somewhere to the front component system or is it a direct feed from the amplifier?

If I goto a dealer and get this installed; which installers do you guys recommend in the DF/W area?

I'm looking to spend under 1k total to get navi in my car; any shortcuts are appreciated.

Thanks.
