It works fine on most of the stations in Myrtle Beach and some of the stations I can pick up from Charleston. B 92 shows their station name and song playing. Next Media stations just show the station name like Star 92.1, 96.1 KZQ, and Wave 104.1. Also the Quatam stations do the same. Only stations not using the RDS is the Cumulus stations. Anyone know why that is?
