Guys, I noticed that all the new vehicles that I saw in the Manila Motor Show have BUILT-IN HEAD UNITS. Pati yung 06 GV ko built-in na rin. Bakit ganon? Is it more economical for the manufacturers? Di ba mas mahirap or impossible na palitan yung head uni? Does anyone in the Philippines do modifications?
