Hello together!!! I dared it and can only recommend it to anyone. the installation is totally easy. you only have to remove the cover under the steering wheel (is a screw to release), the minus pole of the battery clamp, remove the high-bound plug, connect the lever (which you have previously ordered price approx. 190 öre brutto incl. new steering wheel cover) into the intended hold. fasten the new cover again with screw and finish. you can find pictures and installation instructions at:http://www.bertb.de/z4/tempomat_Z4/http://www.bertb.de/…/tempomat_Installation InstructionsZ4.pdf Greetings Norbert
