I was wondering if anyone has converted their 07 Grand Caravan to a Double Din and how much of a pain was it?

I am looking to install in dash nav/dvd/cd/bluetooth yadda yadda and need a double din unit to do so.

Is their a kit or a writeup?

Also i am going to be installing an overhead dvd player for the kids, Any writeups or how-tos out there?

Thanks for the help.
