Radio Data Systems (RDS) is a sub-frequency of FM radio, sent along with a normal music signal. It allows text to be displayed on RDS-enabled radios. Song and artist names can scroll across the stereo screen plus other information like emergency road closures and parking lot structure vacancies.

The RDS FM Transmitter will digitize song information and send it via RDS to a car stereo (along with music). RDS is available in various vehicle models offered by leading automakers. 

The secret is you may have RDS but don't know it. It is not always activated automatically on your car stereo. Look at your car radio today and look for a button that says "RDS" or "Info."  Press it while you are tuned to the Zephyr KZYR 97.7.  Once it is turned on, you should begin seeing information that will help you like who is that band?  or is I-70 closed?

Don't try this with other radio stations in the Vail Valley though, It's a KZYR Exclusive.
