I am new to the site.....I appreciate any and all help I receive in this matter. I just got the F900 w/ update. This was an upgrade from the f700(i was told it plays dvd's) I had for a month. The disabling of whatever to allow for dvd viewing while driving was taken care of prior to the 900 install. Now the 900 is in and I cant watch dvd's while goin over 15 mph. ???? whats up with that
