Don't know much about the other issues, but the radio station naming uses a feature called Radio Data System (RDS).
Hardly any of the stations in Canberra have the technology (surprise surprise!), but on a recent trip to Sydney, most of the stations I tuned into would show the station name. I don't know if this can be turned on and off in your system, but it might give you a starting point to look for in your manual.
