Hi, I. New to pioneer. Just bought secondhand unit and connected it. Entered navigate and found that only can open poi's, recent places, favorites, and traffic further menus. All the rest just grey and inactive. Maps are installed and i can navigate through map scrolling zoooming etc. Went to settings and same there. Only can change Av video and Av audio settings.removed antitheft panel and placed back. Been asked would I like to setup the password. Pressed yes and all keyboard letters were also greyed and inactive.
