      Tech Tips


      • As digital TV is a terrestrial broadcast, the digital TV antenna cannot receive the signal in places where the signal may not reach the vehicle, such as mountains or tunnels.

      • Even in areas where digital TV broadcasts for households can be received, the in-vehicle digital TV may not be able to receive the broadcast.

      Check the digital TV tuner reception level.

      Tech Tips


      • Do not depend solely on the reception level as a reference value as it may vary depending on signal conditions, such as wave interference.

      • If the result changes after turning the vehicle around, it is not due to a malfunction, but is caused by a local weak electric field.
