New here.
Been searching the web hi and lo for information on swapping the head unit with a plug-and-play that is compatible with the sync system. I'm looking to have DVD and GPS capability and I want to install a monitor for passengers in the back. So I'm looking for a unit that is compatible for the Ford system without losing all the options that it currently has. Mine is a limited 2010. Thanks in advance for all the help fellas.
I've attached a picture of the head unit that my vehicle currently has in it and I'm wanting to swap.

I would recommend you talk to Crutchfield about your designs. They were very helpful to me when I changed mine out.

These people can help you a bit also, especially with OEM stuff:
