DIN is an acronym for the roughly translated "Deutsche Institut fur Normung," a German standards and measurements organization. For our purposes, DIN simply indicates that a device complies with a generally accepted standard of dimension or configuration.

A DIN receiver, for example, is one that will fit in a dash opening having a width of 7.2 inches and a height of 2.11 inches, typically mounting with a rectangular metal bracket (DIN Sleeve) provided with the receiver.

• The DIN sleeve is designed to mount in the radio cavity of the vehicle. It features a flange on the front edge to allow the sleeve to flush-mount in the radio opening.
  Some DIN sleeves have a distinct top and bottom - check for "TOP" stamped on the sleeve!



• Once inserted, a series of "V" or "U" notches stamped in the top and bottom of the sleeve can be bent behind the vehicle's trim panel (or installation kit faceplate) with a flat-blade screwdriver or similar tool to secure the sleeve in place. Typically not all notches will be able to be used.



• Following the installation of the sleeve, the receiver slides into the sleeve where it locks in place. This is accomplished by a combination of small clips on both the receiver and sleeve. The location of these clips often vary based on model or manufacturer. It is important that you use your receiver's included DIN sleeve for proper mounting.



• Most manufacturers include specific removal tools to release the receiver from the sleeve. Be certain to keep these tools should removal be necessary.
