i bought a avh-p5700 from an ebay store for my gf. the pic he had on there showed the backround graphics to be descent. the whole idea was that my gf wanted one with cool backround graphics so i whent along and bought it. to my supprise, its just plain blue no special graphics of any and just sucks to even show people. it doesnt even have any color except for when watching dvd. thats why i want to know if i can connect a seperate brain that has graphics, not the vehicle dynamics one either
