"MUTE" control function
If your radio head unit has a button on the right side of the station presets that has a printed "PTY and "RDS" on it this info is most likely useless.
If your radio head unit has a button on the right side of the station presets that has 2 horizontal slashes ( - - ), and a small display above that button seperate from the main dislay, then this info should work for you.
The reason for this seems to be that the slashes indicate variable/choosable functions for these button positions. Obviously, the printed ones have pre-determined functions only (PTY/RDS)
1) turn the radio off
2) turn it back on again & dont touch any buttons
3) hold down the 'M' on the right for 10 seconds, this will bring up the radio head serial #
4) depress the '+' key on the left under the volume knob 6 times until the word "AREA" displays it should say USA next to it
5) now depress the position #1 preset button until the words "AREA OC+RDS appear
6) turn the radio off and your new choices will be set
There is a small display to the right of the large display which originally should have displayed RDS*PTY
When your thru with this reset, it should display RDS*MUTE
When you press the slash under MUTE, it soft'fades out to just above silent, push again and it fades back up to the preset volume level
