RDS AF (Alternative Frequency) is not working for me.
Should I have to turn on somewhere?

Nothing to change in new firmware  
Why?

And why forget the name of the memorized radio stations in a few hours?

n some car's the 12V ACC and 12V from Battery are exchanged in the ISO harness cable. Change the red cable with the yellow cable in the ISO harness cable and look.
