THINKWARE / INAVI users, any feedback from you. Installed mine THINKWARE INAVI FXD700 some 3 weeks ago and was very happy with the unit. Have upgraded to the 'English' version and ha..ha..., missed the sweet Korean voices everytime switch on the unit. Think same voice used in 'English' version but wondering if it is the same girl. As it comes with a rear cam, I had also just installed a small screen to view what had been recording and using the rear cam to assist in reversing. Just curious to find out if there are any other problems users face.
