Radio Data system i think, i know what it does though, its what lets you view the song artist and title, when using F.M. radio, this depends on the radio station too though.

Radio Broadcast Data System is the official name used for the U.S. version of RDS, though the "RDS" name seems to be at least as common in usage. The two standards are nearly identical, with only slight differences, mainly in which numbers are assigned to each of 31 musical and other programme formats the RBDS system can identify. RBDS was approved by the NRSC, RDS by the EBU.

Both use a 57kHz subcarrier to carry data at 1187.5 bits per second. The 57kHz was chosen for being the third harmonic (3×) of the pilot tone for FM stereo, so it would not cause interference or intermodulation with it, or with the stereo difference signal at 38kHz (2×).
