my acura has no navigation system but i want to put the screen,but all i want is to play movie in the screen i dont want navigation,so i need to know what i have to when i buy the screen,all i need is play movies in the screen help,not to active the navigation

 

are you buying the screen that would come with the car?
or like an audio after market screen?

 

that is a giant pita and you are better off not messing with it

the radio controls the HVAC system and to change it over means big $$ and changing a lot of parts behind the dash
