Ultimate Lock Pick

Hello, I have a 2005 Prius w/ JBL 6cd changer and I am interested in the Ultimate Lock Pick. I have seen the website on it but wasn't able to gather all of the info. Was wondering if someone who has it with their prius (preferably an 05) can give me some more clearer info on what exactly it does. I know it disables the i agree screen and allows you to input destinations while in motion. I have seen videos of it playing dvd's as well. Do the DVD's only work in the DVD player under the driver seat, and is there only one DVD slot (can't use maps at same time)? Also, will the JBL 6cd changer take DVD's (probably not)? Any one who has some experience with this, if you could give me some input, I'd appreciate it. Thank you!
