How will I go about doing this because I want to add a DVD MP3 player to my setup. Do I just tap those wires into the stock adapter with my old HU?

 

Are you just adding a DVD player? or a HU with a DVD player? If a new HU then just use that, and toss the current one. If just a player than for sound an AUX input Or an Fm Modulator would be needed.

They are both HU's for the car. I would ditch the HU that doesn't play DVD's and what not but I like the way it gives my interior some character and the DVD HU is ugly and I just want to use it to play my dvd's. I am getting a separate screen so it's not indash.

 

why dont you get a pioneer dvd/mp3 player? its a DIN so it just goes below the HU and its all good : ) there is like a play and stop button on it, so the player isn't even a h/u. Then you dont have to be a weirdo with two hu : )
