XHACD-FM is a radio station on 92.1 FM in Acapulco, Guerrero, Mexico.
The 500-watt station, initially owned by Ruben Nava del Villar Sánchez, was sold to Radio Mundo de Acapulco, S.A. within five years.
The concessionaire name references the Radio Mundo standards format, similar to XEN-AM in Mexico City, that XEACD ran in its early years.
In 2017, the station changed from Los 40 to "Retro FM", a Spanish classic hits format, as part of a wider breakup between Audiorama and Televisa Radio.
On November 1, 2019, the station's Retro format ended and it began broadcasting the talk programming of Heraldo Radio.
