I purchased my F900 a few days ago and had it installed by Best Buy. Everything works perfectly, however I noticed something extremely peculiar. My GPS menus and my DVD player do NOT lock out when the vehicle is in motion. I took my car onto the freeway and have successfully been able to watch a DVD disc and manipulate my navigation controls while driving 65mph+. I have not hacked, nor have I attempted the hardware bypass on the unit. Maybe Pioneer gave up and quit trying to protect us because we hated these safety features so much. I'm really curious to find out.
