Lil bro's got a beat 725 head unit with motorised/touch screen, although it didn't come with any installation instructions... I've put plenty of normal CD units in so plugged it all in with the normal connections that i know, but there are still connections there for, what i'm guessing, extra screens.. Although when we try to play a dvd, we only get sound and no picture so i'm not sure if these connections should be used? The only thing is, the screen works when playing a CD etc.
I'm not sure if theres a faulty connection or if theres something i should be doing different? If anyone knows of something to try it will be greatly appreciated!
