Radio head unit with dynamically updated tunable channel listing

A computing system configured for performing a set of acts comprising:

• encountering a trigger to update a list of currently tunable radio stations for a media playback device of a vehicle;
• based on encountering the trigger to update the list of currently tunable radio stations, updating the list of currently tunable radio stations using a location of the vehicle and radio station contour data stored in a local database of the media playback device;
• and
• displaying a station list using the list of currently tunable radio stations, wherein the list of currently tunable radio stations identifies one or more radio stations that are:
• receivable at the location of the vehicle without interference from other radio stations broadcasting on a same frequency as a frequency on which the one or more radio stations broadcast, receivable at the location of the vehicle with a signal strength that satisfies a threshold condition, or both.

A non-transitory computer-readable medium having stored thereon program instructions that upon execution by a processor, cause performance of a set of acts comprising:

• encountering a trigger to update a list of currently tunable radio stations for a media playback device of a vehicle;
• based on encountering the trigger to update the list of currently tunable radio stations, updating the list of currently tunable radio stations using a location of the vehicle and radio station contour data stored in a local database of the media playback device;
• and
• displaying a station list using the list of currently tunable radio stations, wherein the list of currently tunable radio stations identifies one or more radio stations that are:
• receivable at the location of the vehicle without interference from other radio stations broadcasting on a same frequency as a frequency on which the one or more radio stations broadcast, receivable at the location of the vehicle with a signal strength that satisfies a threshold condition, or both.
