I am not aware of a kit. You have a lot of checking to do, you need to establish. If your existing mirrors have the motors fitted and the loom in place you will need the drivers door master switch witch includes the mirror operating button. The complete mirror assemblies are horrendous in cost (even on Ebay) With any luck all the wiring is there by default but I am not sure. If it is then it's mirror motors and micro switches and the master switch. Then with BMW 1.4.0 or INPA you can code them to work Good Luck let us know how you get on
