thanks to all of the great contributions to this forum, i have been running 3.0 (x series image) on my f700 with the nav voice mute button. I accomplished this without problems and all has been running smoothly. Now that the official update is out and being used, i am considering buying and installing it. So i was wondering if anyone had done this and exactly how you went about it and how it worked out. would there be any problem going from the x series image to the official f series 3.0 if i just put in the SD and fired it up or will it think it is already updated and stop. thanks again.
