Looking to buy whatever it takes to play DVDs on my stock screen

Hey guys,
I have a 2005 Prius that is base (no navi and no reverse camera). I am wanting to be able to watch dvds on my screen though. I have heard lockpick and canview and am not sure what I need, but if anyone is selling whatever I need please let me know. I have heard that the canview gives many more options than I really need, so I guess the lockpick is better if it works on a base model 2005.
thanks
