My 09 Charger factory radio will sometimes default to displaying the RDS Dynamic PS message on the screen. It might work for several weeks and then start only displaying the clock time. I can always press the Info button to see the RadioText RDS message but can no longer see the DPS message. I cannot seem to figure out what is causing it to decide to stop/start working but the DPS is very helpful, especially since I work in radio and need to test the RDS feed at various time. I've tried pressing various button combinations to see if I am accidentally enabling/disabling the DPS but to no avail. I've also Googled but cannot find any support info on the issue. Thanks for any helpful feedback!
