Hi my radio use to show me who sings the songs when on the radio is on. Now it doesn't show it. Is there a way to turn it on? please let me know. thanks

 

Did you Read your owner's manual ?
Just turn the RDS on.

 

Is there a way of making the default display the RDS information instead of it just appearing for a few seconds when you press the info button? In other words it would display the song title / artist as the default, rather than the frequency?

This is not covered in the manual.
