I have a Becker RB3 navigation/CD/Radio unit in my Grand Voyager. It will not shut down. All it says is "Please wait..." and nothing happens. Same thing when trying to set clock. "Please wait...". I suspect it also drains the battery. Anyone have any ideas?
Thanks!

 

Is the Nav disc in it? but it should still shut down with the key out. If not pull the IOD fuse wait for a minute and pit it back in and retry. You may need the code after

 

Thanks.
Same behavior with or without Nav disc. And I had the radio demounted for several days to save the battery - still the same when remounting it in the car.
