Hello! Today we are in Volkswagen Polo with this small radio unit. And I’m going to show you how to enter the hidden menu …in this radio. So turn the radio on. Then press and hold the SETUP button. Wait few seconds. And we have the service mode (the hidden menu) over here. First option is to update your software version. The second on is the radio tuner status. You have your frequency, what’s the RDS radio name, what’s the signal quality. And few other values that will help you diagnose and troubleshoot some issues with your radio reception. and to exit it just press the arrow in the upper-right corner. Turn off the radio and that’s it.
