Newbie - Please Help - V1 Install & Nav/DVD in Motion

[KDD]

Hello All,
I finally discoverd this board after being a roadfly member for years. Getting rid of my '02 4.6is this month and getting an '08 4.8i.

I have two main questions if you could please help...

1) I had previously installed a V1 radar detector into the garage door opener/panel in my '02. Can I safely remove the splicing wire from the old car that came with the V1? Or should I order a new one? Also does anyone have step by step detailed install instructions with pictures for the new 07 or 08 model year? I am not very good at this stuff and it would really help. I just want to do the same thing and clip the V1 to my driver's sunshade and have the wire connected to the overhead console anywhere.

2) The 08 comes with a 6disc DVD instead of CD changer. You can actually watch DVD's while NOT in motion. Does anyone know how to override this or buy an add on to overide it so that you can watch in motion?

Thanks
KDD
