TMC (Traffic) Status

This diagnosis checks the current state of the RDS-TMC reception.

  1. Provider Count: The number of providers that can be received.
  2. Frequency: Frequency receiving at this time.

To start the TMC status check, select the Provider Count and Frequency you want to check, then select Start.

There are two modes to check the TMC status. The modes cannot select manually

  1. Synchronous mode
  2. Asynchronous mode

This diagnosis checks the following status. Block Search Time, Uncorrected Blocks/min, and Message Counter are indicated at the Synchronous mode only.

  1. Field Strength: Displays reception sensitivity.
  2. Block Search Time: Displays the time until changing to the Synchronous mode.
  3. Uncorrected Blocks/min: Displays the number of block errors per one minute.
  4. Message Counter: Displays the number of message that is received.
  5. Error Status: Displays RDS error status; 0: No error 1: Cannot receive TMC 2: Bus error 3: Decoder error 4: Undefined error

USB Memory Info

This diagnosis displays the USB device status that is connected to the audio-navigation unit.

If the USB memory device is connected to the USB update port located in the passenger's dashboard area behind the glovebox, the screen displays the USB memory size, the Product ID, Vender ID, and connection status (Inserted/Not Inserted).
