I would love to see an upgrade radio chip that supports RDS (especially RDS-TMC) decoding.

RDS can carry all kinds of metadata that can be useful to people, especially while on the road:

• TMC: Traffic Message Channel
• CT: Clock Time
• AF: Alternate Frequency (when a signal is getting weak, an alternative frequency for the station can be indicated)
• PS: Program Service (station identification)
• RT: Radio Text (artist, title information, etc)
