HD RADIO™ TECHNOLOGY

HD Radio™ systems provide digital radio broadcasts on AM/FM radio, alongside the analog radio signals. HD Radio™ technology is capable of providing improved audio quality compared to the analog broadcast.

HD Radio technology operates in a very similar way to the standard AM/FM system. For information on storing stations, waveband selection, etc., see RADIO CONTROLS.

When an HD Radio signal is detected and received, the tuner gradually blends automatically between the analog and the digital audio.

The HD Radio digital signal is transmitted at the same frequency as the analog signal and can also provide extra multicast channel services, where available.

In areas of poor reception, due to signal masking and transmitter strengths, the HD Radio system may switch between the HD Radio's primary signal and the corresponding analog broadcast. If tuned to a multicast service, the audio may mute.

NOTES

During this process, a change in volume levels may be experienced. The volume matching between the analog and digital signal is dependent upon the broadcaster.

NOTES

If poor reception and auto-switching becomes unacceptable, it is recommended that HD is switched off or the radio tuned to a HD Radio service with better coverage.

NOTES

Some types of body-mounted accessories (for example, roof rack and loadspace lid stowage devices) may affect the performance of this system.

To switch the HD Radio feature on and off:

  • Select Settings.

  • Select HD Off to deactivate or On to activate HD Radio.
