all you have to do is hook your playstation up to either the av1 or the av2. are you planing on useing another moniter? if you do that, you can either play the ps2 on one or both moniters orplay the ps2 on the external moniter and watch and listen to the d3. i have a ps2 and alot of times i watch and listen to vidios through the d3, and play the ps2 on one or all of the 3 other moiters in my car.its also usefull to watch dvds on the playstation and a seperate moniter and listen to it through the d3 and still bring up your nav. via the map button.
