Note:
This TSB only applies if the vehicle has HD radio.

Technical Background
If a radio station is stored while the user is listening to the HD broadcast, the preset will be stored as an HD radio
preset (Figure 3). As a result, even if the HD Radio setting is turned off in the MMI, it will be automatically turned
back on whenever an HD Radio preset is selected. The user must store all FM & AM radio presets as analog
stations (Figure 4).
