Guys I am Installing a Dashtop(Car-Pc) in a ford Flex 2009 Limited. I would like to keep the existing Single DIN Disply as it Displays the TEMP Control. I am going to remove the audio contorls and cd changer and fabricate the frame for my 7 inch touch screen.

While I do all of this i am not sure if the other car features such as temper control, Parking Assistance and all will still remain intact. Could someone please guide me out.

There is a device by www.Pac-audio.com that is used to replace radio with other oem car audio but i dont know how to connect these to a car pc.

Also can OBDII be used for AC controls and Parking assistance that already exists on the car ?

I have attached a pic of the Car Dash
