I'm not a fan of aftermarket installs as the install is only as good as the shop itself. I know too many friends that have the roof type install and they have failed and are now left with a nice paper weight on the ceiling.
What CBR said! To add to this however, if money isn't much of an issue get the dealership to install a factory unit. I have one buddy that did this as he had a quality audio shop do one in his minivan that turned out to be junk. Sometimes the extra expense can be worth it in the long run.
I had a headrest system in my old truck and wasn't that happy with it. I have the factory system in my Ram and will have one in every vehicle I own from here on.
