Does Non-Nav Prius JBL or Blu Logic Bluetooth Support Your Custom Ringtones?

If you have contacts with custom ringtones, do you hear those customized ringtones over the sound system when connected handsfree or does the bluetooth speaker just play a generic ringing sound?

If your custom ringtone works, it would allow you to identify the caller without looking at your cell phone screen just by the ring sound when your JBL radio displays the useless "INCOMING CALL" text or if you have the dealer installed Blu Logic.
