well it depends what frontend you are using. i know that Centrafuse by default will not allow you to do a bunch of things while the car is moving, such as go into windows, watch movies, and some of the other that im not sure of are type in address and use the web browser. the reason im not sure is because i disabled that feature. i dont watch movies or anything but i hate being limited. the system works off of gps movement. if your going faster than 5 mph it disables those things. Im not sure if anyone else does it, but imo centrafuse is the best front end. i know its a matter of preference but ive never been able to get the clean oem look out of any other frontend, no matter what skin i use. also centrafuse really shows itself to be the complete all in one system, exemplified by this exact feature.
