The pri­ma­ry pur­pose of portable nav­i­ga­tion sys­tems is to pro­vide dri­ving direc­tions, but man­u­fac­tur­ers are adding oth­er fea­tures such as audio, video, pho­tog­ra­phy and lan­guage guides. Most of the enhance­ments are for enter­tain­ment, sup­ple­ment­ing AM/FM radios and CD play­ers.
