To insert deblocking скобу (sometimes enters into the complete set with built in autoradio) in four apertures on corners of the forward panel and to pull out autoradio from the central console. Or to insert four suitable nailing or a wire piece in apertures and them to deblock fixing springs. To pull out autoradio forward, if necessary in addition cautiously hooking a screw-driver. To remove wire and aerial sockets. At installation to watch that the fixing pin of autoradio has behind entered into the eye intended for it in the instrument panel. For this purpose it is necessary to hold autoradio absolutely horizontally. A few to press radio into an assembly aperture that fixing springs were latched. To type a number code at models of autoradio with the anticreeping coding according to the maintenance instruction.

 The help: the protective number code will be necessary for entering anew and in case of a detachment of the storage battery, replacement of a safety lock of autoradio or separation of wires of giving of a food for autoradio.

At the left: on an illustration removal of autoradio by means of two deblocking скоб (1 and 2) is shown. Deblocking скобы press on fixing springs (3), disconnecting them, thanks to it it is possible to take out radio from an aperture for embedding.

    Small screw-driver cautiously to lift a covering dynamics and to remove it. Itself динамик it is fixed by means of two screws with crosswise шлицем. At installation to press fixing pins in dredging on the instrument panel.

Back dynamics are located in a covering of doors.

At the left: after the detachment dynamics attached to an underside of a covering of a door (black arrows specify in fastening points), becomes accessible динамик (2). It also is screwed directly on a covering (white arrows show on fixing screws).

On the right: high-frequency динамик (2) it is established separately and fixed by a carving ring (1).

Dynamics in a covering of back doors

If back dynamics have been established at factory they are in a covering of back doors.


    To remove a covering of doors. To disconnect динамик on a covering underside. To weaken three fixing screws dynamics and to disconnect a wire. High-frequency dynamics: to turn away a carving ring behind on dynamics, to disconnect a wire.
