HD radios provide a clearer audio signal than the standard audio received by older AM/FM radio stations. Although these radios do receive the older radio signals the devices specialise in HD radio stations (just like a blu-ray player is capable of playing standard DVDs, but it specialises in HD movies). Of course, to make sure you obtain the best signal possible you must first move your vehicle to an adequate location to find the best signal.

Things you need
- HD radio
Drive up out of any underground parking structures or garages. The concrete blocks out the HD signal, reducing the quality of the radio stations.
Avoid large cities, if at all possible. The large buildings prevent the radio signal from reaching you and the glass of many tall buildings bounces the reception away from your vehicle.
Avoid using your cell phone if the radio begins to drop in and out. Sometimes the frequencies from the cell phone distorts the signal from the HD radio source.
Check the cable connection running from your car's radio to the attached HD radio (if the HD radio is an attachment and not built in). Make sure the cable is completely inserted into the back of the receiver. If not, the receiver does not get all the power it needs, reducing its range and bringing down the audio quality.
Remove anything stuck to the HD receiver's antenna. if there are any stickers, branches or leaves stuck to the receiver, audio quality drops off.
