Report "Unit worked satisfactorily for a couple of years. Now when it is charged and turned on (or connected in the car), all that can be seen is the first screen that shows a picture of the world and the words: "AMCOR" and "Amcor...wherever you go!" No action, including using the reset, menu or start buttons in any combination will get the unit to go beyond this screen. Should I just discard the receiver?"
