NAVIGATION SYSTEM RDS-TMC does not Function

INSPECTION PROCEDURE

Tech Tips


  • RDS-TMC function settings can be changed by the user.

  • Before troubleshooting, check the settings on the menu screen of the navigation system, and confirm that the relevant item settings are correct.

  • The RDS-TMC function of the navigation system operates in the same way as the radio, according to the signals received by the navigation receiver assembly. It is therefore necessary to also check that the RDS-TMC function of the navigation receiver assembly is normal.

  • A short period of time may be required to update RDS-TMC signals depending on the signal reception conditions.
