The FAST 2.0 comes with a small computer touch screen that is used to set the system up and to let you monitor things when you're done. My son decided that he wanted to have easy access to it but he didn't want to leave it exposed all the time. It does come with a windshield suction cup mount but my son didn't feel that it would be convenient if he had to constantly pull it on and off. Despite my objection to doing it, he wanted the ashtray modified to accommodate the monitor. Because there was not enough space inside the ashtray to allow the door to close with the screen attached, I had to gut it and rebuild.
