A vehicle has a lighting control module and a HD radio receiver. The lighting control module provides an indication of daytime operation of the vehicle and an indication of night-time operation of the vehicle. The HD radio receiver is configured for selecting between outputting digital format audio content of a radio signal and outputting analog format audio content of the HD radio signal dependent upon a HD signal sensitivity threshold. The HD radio receiver sets the HD signal sensitivity threshold to one of a plurality of different night-time HD signal sensitivity threshold values as a function of a signal strength characteristic of the HD radio signal when the lighting control module provides the indication of night-time operation thereto. The HD radio receiver sets the HD signal sensitivity threshold to a daytime HD signal sensitivity threshold value when the lighting control module provides the indication of daytime operation thereto.
