so i tried to bypass my parking brake to watch movies and get full navi menu. it works perfectly fine when stopped but as soon as i start moving the video turns off, but then when i come to a stop sign or w/e it turns on again, the only thing i can think of is that the navi is seeing that i am moving and turns it off. does anyone know what wrong or can give me specific step by step instruction on how to get this bypass to work corectly, pics would be great if thats possible
