Here is the auction. It ends today no Visit My Website
it was taken out of my 530xi. You may need a $5 part from bmw to get this to work with your prewired e60. There is a part called the fiber optic sleave or envelope which allows you to insert the optic cables into the harness plug. Plus its 1-2 labor charge to program car at bmw. If you had a cd or ipod and you are replacing it with this then you are ready to go
