This is an '02 530i with wide screen monitor. When car is started a "Warning" page comes up on the Nav screen. Pressing the "Accept" icon (touch function) does nothing, "Warning" page stays on the screen. Radio works.

Is there a way to clear/reboot via battery disconnect? Can this page be made to go away forever? If I'm not mistaken this is the only "Touch" function on this screen, correct? So I don't know if any kind a reset will bring back touch respones.

Didn't have a Nav manual at first but do now and it mentions nothing about "Warning" page. When menu was accessed before this started happening the screen looked fine.
