DIN stands for "Deutsche Industrie Normen" which the Germans starting using to standardize radios in Audis, BMWs, Mercedes, and VWs in the mid 80’s. It has since become the industry standard.

These kits enable you to mount a RetroSound® Laguna, Hermosa or Long Beach radio into vehicles that have been either altered to a modern DIN opening (7-inches x 2-inches) or originally came equipped with a DIN-sized radio.
